Boiler specifications

Looking at the owners' reviews of gas water heaters Zhitomir

, it becomes clear why this manufacturer’s equipment stands out so much, why it is so in demand and important.

The equipment is distinguished by a large number of characteristic positive properties when compared with similar competitors. Yes, like any other devices, boilers of this brand also have disadvantages, but in comparison with the large number of advantages, any inaccuracies are insignificant.

Let us note the main positive qualities that Atem gas water heaters have:

A heat exchanger made of steel, which makes it possible to transfer to water the maximum heat energy that is generated when fuel is burned.
Full compliance with all Western standards.
Good and reliable burner design. Thanks to it, the heating unit is considered highly efficient and emits a minimum of substances that are harmful to health during gas combustion.

Technical parameters of Atem gas water heaters

Atem company produces:

gas boilers for floor Zhytomyr ;
wall devices (parapet).

Units installed on the floor are also divided into single-circuit and double-circuit. Devices with 2 circuits heat water for two or three consumers at low costs. See the technical properties of all Zhytomyr floor-mounted gas water heaters all together.

The productivity of the hot water circuit for floor-standing installations with 2 lines is from 175 to 1400 l/h with a temperature difference of the heated liquid of 35 °C. The device can be equipped with a circulation pump, which is mounted as a function. Parameters of a number of models of double-circuit Zhytomyr parapet type in the table.

Parapet 2-circuit units provide warm water flow from 160 to 345 l/h with a liquid temperature difference of 35 °C.

From the tables we conclude and make sure that the wall-mounted and floor-standing boilers of this manufacturer are adapted to the conditions of low gas pressure in pipelines, and this is their big advantage. A significant disadvantage is the maximum coolant pressure in the heat exchanger, which is possibly very low. For boilers installed on the floor, this is up to 2 kgf/m2, and for suspended boilers, up to 0.7 kgf/m2. Then how can foreign analogues operate at a system pressure of up to 3 kgf/m? Thanks to this, you can make sure that Atem gas equipment is more suitable for gravity systems and small houses with one or two floors.

Professionals do not recommend purchasing wall devices for two-story cottage buildings, since the pressure simply will not be enough for the system to work well.

When, in addition to heating, you also want to receive warm water, it is better to choose models with 2 circuits.

Range of gas parapet boilers

The parapet-type gas boiler “Zhytomyr” is an inexpensive device for organizing water heating of a small country house with an area of up to 150 m². It successfully combines elements of turbocharged and atmospheric boilers - a closed combustion chamber and a coaxial chimney in the absence of a blower fan.

The movement of gases through the coaxial chimney of a parapet heat generator occurs naturally, without a fan or smoke exhauster

Principle of operation. The heat generator, suspended from the wall near the floor, burns natural or liquefied gas without pressurization. Combustion products are thrown out through an internal short pipe passing through the wall. Air enters the firebox through the external channel (outer pipe) naturally. New versions are equipped with 2 separate pipes - smoke and air.

The line of parapet models "Zhitomir-M" includes 5 single-circuit and 4 double-circuit boilers, designated by the abbreviation AOGV-SN and ADGV-SN, respectively. Thermal power of the devices is 5, 7, 10 and 15 kW. Let's reveal the design features of heaters:

the material of the main heat exchanger is steel, the secondary heat exchanger for hot water supply is copper;
combustion chamber – completely closed;
burner - tubular type, safety automatic - gas valve SIT 630 made in Italy;
ignition – piezoelectric, from a button on the valve;
4 fittings DN40 for connecting the heating system - two on each side of the housing.

The boiler comes complete with a gas-air unit (otherwise known as a coaxial pipe), a flexible pipe for connecting to the gas main, fasteners and an asbestos sealing cord. The cost of a single-circuit unit with a power of 5 kW (heated area - 50 m²) is 270 USD. e., double-circuit 15 kW - 475 USD. e.

New version of wall heat generator with separate pipes for air and flue gases

Reference. Up-to-date information on the pricing policy and offered models of heat generators can be found on the official resource at: shop.atem.ua.

Specifications

The Zhitomir-M parapet boiler has the following operational parameters:

fuel efficiency (EF) – 90%;
minimum inlet gas pressure – 6.4 mbar, maximum – 17.6 mbar;
operating pressure in the heating system – 1.5 Bar, maximum permissible – 2 Bar;
coolant temperature at the outlet of the heat exchanger – no more than 90 degrees;
the amount of water in the boiler jacket is from 5 to 19 liters;
maximum pressure from the cold water supply – 6 Bar;
The dimensions of the largest device in the line are 360 x 495 x 825 mm (LxWxH).

Natural gas consumption, hot water output and the size of the chimney duct depend on the power of the heater. The specified characteristics are presented in the table, in more detail on the manufacturer’s website.

Advantages and disadvantages

The most important advantage of Zhytomyr parapet boilers is the price that is affordable for people with average and low incomes. Heating installations can be freely purchased in Ukraine and the CIS countries.

Let us list the other advantages of chimneyless heat generators:

Energy independence. The boiler does not require electricity, although it can work in conjunction with an external circulation pump.
Small size and simple design.
Reliability and safety provided by proven gas automatics from the EuroSIT brand.
A full-fledged smoke channel is not required.
The double-sided arrangement of the fittings expands the possibilities for connecting heating network pipes.

Important point. You should not perceive the listed nuances only in relation to Zhytomyr devices. The market is saturated with parapet clone boilers with similar pros/cons.

Design diagram of a double-circuit version of the heater
Despite the low threshold of permissible coolant pressure (2 Bar), wall-mounted boilers can operate as part of closed systems with a membrane expansion tank. The main thing is to maintain the specified threshold when filling with water and adjust the pressure inside the air chamber of the tank according to the instructions.

Since we profess the completeness and reliability of the published information, we will reveal the shortcomings of the Zhitomir-M heaters:

The degree of automation of the boiler is minimal and includes only a set of safety functions - protection against attenuation, overheating and a critical decrease in pressure in the gas pipe.
If the wall faces a windy passage, the burner may periodically go out. The problem is solved by installing an additional screen on the windward side of the chimney.
The performance of the hot water heat exchanger is enough to serve 2 consumers with low consumption. If you turn on the shower and the kitchen faucet at the same time, the water temperature will become uncomfortable for washing.
A constantly burning pilot light wastes fuel. This fact is critical for residents of Ukraine and other countries with high prices for main gas.
Manual ignition mechanism.

All safety, heating control and gas supply functions are concentrated in the 630 SIT valve.
The disadvantages of heat generators are not critical and are a consequence of the maximum simplification of the design and cost reduction. At the same time, the service life of inexpensive Zhytomyr boilers reaches 15 years, taking into account minimal maintenance.

Design features

You can take a look at the general structure of the Zhytomyr unit.

Installation of a gas boiler Atem Zhytomyr

The design features of the heat generator provide independence from electrical energy for absolutely all models of the company. The burner is atmospheric and single-stage, with a simple system, brand POLIDORO, bought in Italy, very reliable and durable.

The automation for Zhytomyr gas water heaters is also reliable; it is also manufactured in Italy. The EUROSIT valve is considered automated, does not depend on energy, is more common among manufacturers of heat-generating equipment; production leaders in domestic and foreign countries install it in their devices.

To transfer heat energy in the heating system of the boiler, a fire-tube heat exchanger made of steel is used. This means that high-temperature smoke gases pass through several pipes immersed in a water jacket. They transfer their heat to the liquid and come out at a temperature of 110-150 °C. The pipes have a cross-section with right angles, and this creates a larger exchange surface area and makes the boiler work more effectively. In models with 2 circuits, there are copper coils around the heat exchanger pipes to heat water for domestic needs.

Movement of smoke gases

To slow down the movement of smoke gases in flame tubes, in pipe coils of mounted and floor-mounted units, turbulators are used. Their backup function is to collect soot deposits remaining on the planes of these parts, which are placed perpendicular to the gas flows, and soot deposits almost do not stop on the walls of the pipes.

In the future, soot can be easily removed from the turbulators, just as when dismantling a heating device, they are removed from the flame tubes. A similar characteristic provides a chance for the surfaces of the flame tubes inside to remain clean and transfer heat energy well to the water jacket. Otherwise, the soot layer that settles on the walls can greatly reduce their thermal conductivity, and the temperature of the outlet gases will become higher, and the heat will go outside.

Gas water heaters Atem Zhytomyr will work well with chimneys with low draft. For this purpose, the equipment has a direct damper, which opens the way for smoke gases to escape without affecting the heat exchanger.

It works like this:

Before ignition, the damper is opened. There is insufficient draft in the chimney.
The valve adjustment wheel and the piezo ignition button are pressed in stages, the ignition wick lights up.
The wheel is turned a couple of times, gas is supplied to the burner and it lights up.
High temperature gases (up to 200 °C) begin to flow directly into the chimney. Due to the temperature difference in the chimney, the draft increases and the boiler enters operating mode.
After approximately 6 minutes, the damper is closed and the liquid begins to heat up, but the high traction force remains.

A mounted gas Zhytomyr boiler without a chimney is almost similar to the design of floor-standing equipment. The difference is in the design of the chimney; in suspended units it is coaxial. This is a double-walled pipe through which gaseous, liquid and solid substances move, and street air moves towards them between the walls of the inner and outer pipes.

The burner takes oxygen for its operation not from the room, but from the street, and the combustion chamber is of a closed type. In similar foreign units, a ventilation device is built in for air circulation; in Atem boilers, the overall process is independent of energy and operates with natural draft.

Owner's review of the Zhytomyr heating boiler

Floor-standing boilers "Zhytomyr-3"

The reliability of the stationary units of the model range has been tested by many years of practice. Heaters “Zhitomir-3” are among the most popular; they are recommended to be purchased by gas service technicians.

Explanation. Gas workers really “love” the floor-standing boiler models of the Zhytomyr brand. The design is simple and reliable, malfunctions occur extremely rarely, and accordingly, the technician has less work to do.

The line includes 18 devices - 9 single-circuit models KS-G-SN and 9 heat generators KS-GV-SN with an additional water heating heat exchanger. Main characteristics of boilers:

range of covered powers - 7...60 kW, efficiency - 92%;
the material of the main heat exchanger is carbon or stainless steel, the secondary coil is copper;
burner – tubular micro-flare from Polidoro, combustion chamber – open type;
there is a constantly burning igniter, which is ignited by a piezoelectric element button;
operating coolant pressure – 1.5 Bar, maximum – 2 Bar, permissible pressure in the water circuit – 6 Bar;
recommended temperature schedule - 60...80 °C, maximum - 90 degrees, at 95 °C the overheating sensor is triggered;
removal of combustion products through a traditional chimney with natural draft.

Note. The KS-G-045SN and KS-GV-045SN units with a power of 45 kW are designed for higher coolant pressure: operating pressure - 2 Bar, maximum - 3 Bar.

Design Features

According to the requirements of the regulations, the Atem floor-standing boiler is equipped with an automatic safety system that interrupts the fuel supply to the igniter and the main burner based on four factors: a drop in gas pressure below 6.4 mbar, spontaneous extinguishing of the flame, lack of chimney draft and overheating of the coolant. The shutdown function is performed by an automatic gas valve, whose model depends on the performance of the unit:

7…16 kW devices are equipped with 630 SIT automation.
Heat generators with a capacity of 22.5…31.5 kW are equipped with 710 MINISIT valves.
Boilers with a power of 40 kW and more are equipped with automatic gas blocks SIT 820 NOVA.

Reference. The latest series of Italian valves 820 NOVA is equipped with a connector for connecting weather sensors and room thermostats. You will find more information on the operation of gas boiler automation in our separate review.

The second important feature of domestic heaters is the design of the DHW circuit. The heat exchanger is a copper coil immersed in the water jacket of the apparatus. Therefore, the temperature of the water going to the hot water supply depends on the degree of heating of the coolant in the boiler tank.

In the summer, the operation of the water supply circuit is ensured by piping the boiler - a pipe jumper with a tap is placed between the supply and return. When the heating of the house is turned off, this tap opens, and the heating system is cut off by other fittings. The coolant begins to circulate in a small circle, as shown in the diagram.

For summer operation of the DHW circuit, the manufacturer suggests looping the supply with the return, maintaining the connection between the boiler and the expansion tank

Advantages and disadvantages

The main advantage of floor-mounted heat generators “Zhitomir-3” remains high reliability at low cost of equipment. A single-circuit boiler with a thermal power of 7 kW will cost approximately 300 USD. e., with a water circuit – 340 USD. e.

The remaining advantages of water heating devices look traditional for the Atem brand:

simplicity of design and unpretentiousness in operation;
non-volatile – the boiler does not require power supply;
long service life;
models with automatic SIT 820 NOVA can be connected with external control devices - thermostats and weather sensors.

Addition. The new generation of KS-G-SN models with a power of 10...30 kW is equipped with an Atem-Start lightweight ignition system. The start button is located on the front panel of the boiler.

The units are adapted to work in open-type gravity and pump heating systems. Use as part of a closed circuit with forced circulation is allowed, provided that the operating pressure of the coolant does not exceed 1.5 Bar (short-term - 2 Bar). Let us remind you: the KS-G-045SN modification can withstand 2 and 3 Bar, respectively.

The disadvantages are similar to those of parapet boilers, except for blowing the burner through a coaxial chimney. If the flue pipe is built correctly - the cross-section (diameter) and the height of the rise of the channel are maintained, then problems with draft will not arise.

Model Atem Zhytomyr 3

Undoubtedly, the company’s assortment includes many models with different parameters. However, the sales driver is considered to be gas boiler Zhytomyr

3, so we need to analyze it in more detail.

The model stands out not only for its good price, but also for its excellent technical parameters.

on
gas Zhitomir 3 are usually good. Almost all customers note the small size, convenient operation and reasonable price.

How to light a gas boiler Zhytomyr

There is a regulator with divisions on the boiler, which must be set to zero. Then open the gas supply on the pipe in front of the boiler and press the regulator like a button and light the wick with a match. After the wick is lit, you need to hold it for 10 seconds and slowly release it. Then set the regulator to the desired compartment (approximately 2).

If you are unsure of your own actions, call the gas service. They will tell you in detail and explain how to turn on a gas boiler in Zhytomyr.

Breakdowns

Let's consider the possible breakdowns of gas water heaters in Zhytomyr, which may appear during use, and options for solving them.

All breakdowns of gas communications and gas boiler valves must be repaired only by authorized professionals.

Disruption of water movement

If the movement of water along a closed circuit is difficult or there is no water in the heating system at all, the reason may be hidden in:

insufficient amount of fluid in the system;
presence of air in the heating system;
water leakage from the heating system;
significant scale deposits.

This damage can be removed by taking the following steps:

Refill the heating system with water.
Release the air by filling the heating system with coolant from below.
Identify and clean up fluid leaks.
Clean and flush the system.

Reduced heating efficiency and increased gas consumption

If such a problem occurs, then the reason is most likely the following:

the heating system is installed incorrectly;
a lot of scale was deposited.

To get the system working, you need to:

Correctly install the heating system.
Clean and flush the boiler.

Condensation forms

If drops of water appear and flow onto the key burner, then most likely the reason is the low temperature of the coolant. To remove this nuisance, you need to warm up the boiler.

The burner goes out

Gas boiler Zhytomyr

does not ignite, and this means the acceptable reasons are:

not overheating the thermocouple;
low gas pressure in the system;
damage to the safety automatics or gas valve;
loosening of the thermocouple.

This breakdown can only be resolved by calling a gas service professional.

Cotton when igniting

If a pop is heard when the boiler is ignited, then most likely this indicates a poor fire connection between the ignition and key burners. Gas pressure is too low.

In this case, only a master can help.

Burner extinction

If the boiler is on gas Zhytomyr

If both the main and pilot burners go out, then the reason is poor draft. How to fix this problem? Insulate the chimney and remove air suction.

These are the main reasons why breakdowns may occur with a domestic unit.

Now gas water heaters Atem Zhytomyr

are top sellers in their own position. Good technical parameters, excellent quality and budget price make the brand’s products extremely popular. Having decided to purchase a Zhytomyr device, the consumer remains satisfied with the purchase. Due to the fact that such equipment makes it possible to organize reliable and stable heating of the house.

Reviews about the operation of boilers

As you might guess, the vast majority of reviews are positive. When purchasing a heat source in a budget price category, the owners clearly understand the goal - to ensure reliable heating of the home with a minimal investment. Here are a number of statements from real users.

Azalea, Nikolaev Ukraine

We moved into a private house 8 years ago and immediately began repairing the heating. The old boiler, left over from the former owners, was replaced with “Zhitomir-3”. What I would like to note is that the device functions without interruption, the burner does not go out in strong winds. We wash and clean it every year, there are no problems in operation. We are happy with the boiler.

Layout of the universal device “Zhitomir-10” with independent heating of coolant and water

Alexander, Krasnodar, Russian Federation

I use a 25 kW Atem double-circuit boiler, floor-standing version. Fuel - main gas. Automation and heating work at a solid five, the hot water supply circuit is worthless. To wash properly, you need to set the regulator to 6-7, the batteries get unbearably hot.

Nikolay, Republic of Belarus

Since the heating system of the house is gravitational, I selected the appropriate 16 kW Zhitomir-3 boiler to replace the old Lemax. When starting up, I encountered a problem - the uninsulated chimney began to “cry” with condensation, with the old unit the gases heated up more strongly and a similar effect did not occur. 6 heating seasons have passed since installation, a malfunction occurred only once - the igniter went out. The gas worker advised over the phone to wipe the contacts of the traction sensor with alcohol, and that settled the issue.

Larisa, Perm, Russian Federation

The Zhitomir water heating boiler has been operating in our house for five years, no serious deficiencies have been found. The unit is simple, reliable and unpretentious; it does not need to be serviced by a service organization. We cannot install an open expansion tank, so we made a closed system. Until the gas pipeline was installed, 80 square meters of the house was heated with propane cylinders. True, we had to hire a specialist to switch the boiler to liquefied gas.

How to start a gas water heater for the first time

When arranging a heating structure, many homeowners prefer installing double-circuits. These heating units, when installing the newest models, are distinguished by their reliability, they are economical and allow you to provide hot water in the house, but you need to know how to start a gas water heater correctly the first time.

In order for the device to work for a long time and without repairs, it is necessary to properly organize the first start-up of the gas boiler, during which the system is filled with water and the air that has entered them is removed from the pump and heating radiators. To facilitate this process, specialized devices - air vents - are used for heating devices. They should be unscrewed until water comes out of them. To prevent air from remaining in the pump, first remove the front panel of the unit and make the necessary adjustments. Air pockets are quickly removed, and the equipment is put into operation on its own.

How to start a gas water heater: preparation

There are simple instructions explaining how to start a gas water heater , which is shown in the photo. The initial start-up is performed when the installation and wiring of all components of the heating equipment is completed, and the accuracy of the work has been verified by the relevant authorities.

The location of the heating unit must be selected in accordance with safety standards and regulations that do not allow the occurrence of fires. Boiler

must be at a certain distance from the wall surface, which depends on the manufacturer’s advice. By the way, for certain models of gas appliances this requirement is not considered important. You also need to make sure that there are no flammable materials or objects nearby.

Plus, it is not allowed to place boilers near windows, because their operation is disrupted. The even placement of the device body is of great importance - even slight distortions are not allowed. After installation is completed, they begin to connect the equipment to a source of cold water: remove the plugs from the pipes, and place a filter with a tap with a round hole at the entrance. Such a device protects the heating structure from a variety of contaminants that cause problems. Valves with a spherical shut-off element must be built into all pipe sections used for piping.

Solving the problem of how to start a gas

water heater, great attention should be paid to the pipe connections from the gas main. These installation works are not carried out with one’s own hands, but rather involve professionals from the relevant services who are involved in connecting, sealing and, if necessary, installing a gas meter.

Before turning on the gas water heater , a separate power line should be installed specifically for the heating unit. The equipment must be equipped with an electrical cable and plug, and a socket must be installed next to the device, separating it from the rest. After which the boiler is connected to the chimney pipe, in which the draft and its performance are checked. She should go outside. The installation work to install a chimney depends on the type of heating device.

Having completed preparations for startup, the boiler is disconnected from the electrical supply to fill it and the heating system with cold water. Then they check that there are no leaks, turn on the thermostat to the maximum value so that the operating mode toggle switch lights up in automatic mode.

Rules for filling the system with water before turning on the gas water heater

Before lighting a gas water heater

, and turn on the heating system, first of all it is filled with cold coolant, which, after heating, will circulate through the pipes and heating devices. When performing the first launch, everything is carefully checked so that subsequent work is trouble-free and the equipment does not require repairs.

In the body of the unit there is a specialized tap, located near the pipe section, to supply coolant into the system. During the filling process, the system pressure is monitored due to the presence of sensors and instruments for determining the pressure value. Modern boilers already have them, and there is no need to buy them additionally. When the device is filled with water, the mark on the meter rises. When it reaches 1.5-2 atmospheres, the water supply is shut off and filling is completed.

These pressure parameters can be changed because they depend on the manufacturer's requirements for the operating pressure in the heating system. But filling with cold water does not end there entirely, because replenishment will be needed after the structure is freed from air pockets.

Boiler Zhytomyr

Heating equipment of the Zhytomyr brand “Atem” is widely known in the countries of the former USSR. The plant's products are famous for their reliability, simplicity and affordable price tags. Let us highlight another important advantage - the manufacturer is as honest as possible with the buyer. The documentation for the Zhitomir solid fuel or gas boiler reflects the real operating parameters of the equipment, no overestimation of efficiency or other marketing techniques.

We decided to collect all the heat generators of the Atem model range in one publication and make a detailed review of each line of boilers. The task is to lay out the technical characteristics, identify the strengths and weaknesses of the units. At the end we will attach reviews from owners who use this equipment for heating private houses and apartments.

Range of gas parapet boilers

The movement of gases through the coaxial chimney of a parapet heat generator occurs naturally, without a fan or smoke exhauster

the material of the main heat exchanger is steel, the secondary heat exchanger for hot water supply is copper;
combustion chamber – completely closed;
burner - tubular type, safety automatic - gas valve SIT 630 made in Italy;
ignition – piezoelectric, from a button on the valve;
4 fittings DN40 for connecting the heating system - two on each side of the housing.

New version of wall heat generator with separate pipes for air and flue gases

Reference. Up-to-date information on the pricing policy and offered models of heat generators can be found on the official resource at: shop.atem.ua.

Specifications

The Zhitomir-M parapet boiler has the following operational parameters:

fuel efficiency (EF) – 90%;
minimum inlet gas pressure – 6.4 mbar, maximum – 17.6 mbar;
operating pressure in the heating system – 1.5 Bar, maximum permissible – 2 Bar;
coolant temperature at the outlet of the heat exchanger – no more than 90 degrees;
the amount of water in the boiler jacket is from 5 to 19 liters;
maximum pressure from the cold water supply – 6 Bar;
The dimensions of the largest device in the line are 360 x 495 x 825 mm (LxWxH).

Advantages and disadvantages

Let us list the other advantages of chimneyless heat generators:

Energy independence. The boiler does not require electricity, although it can work in conjunction with an external circulation pump.
Small size and simple design.
Reliability and safety provided by proven gas automatics from the EuroSIT brand.
A full-fledged smoke channel is not required.
The double-sided arrangement of the fittings expands the possibilities for connecting heating network pipes.

Important point. You should not perceive the listed nuances only in relation to Zhytomyr devices. The market is saturated with parapet clone boilers with similar pros/cons.

Diagram of the dual-circuit version of the heater

Despite the low threshold of permissible coolant pressure (2 Bar), wall-mounted boilers can operate as part of closed systems with a membrane expansion tank. The main thing is to maintain the specified threshold when filling with water and adjust the pressure inside the air chamber of the tank according to the instructions.

Since we profess the completeness and reliability of the published information, we will reveal the shortcomings of the Zhitomir-M heaters:

The degree of automation of the boiler is minimal and includes only a set of safety functions - protection against attenuation, overheating and a critical decrease in pressure in the gas pipe.
If the wall faces a windy passage, the burner may periodically go out. The problem is solved by installing an additional screen on the windward side of the chimney.
The performance of the hot water heat exchanger is enough to serve 2 consumers with low consumption. If you turn on the shower and the kitchen faucet at the same time, the water temperature will become uncomfortable for washing.
A constantly burning pilot light wastes fuel. This fact is critical for residents of Ukraine and other countries with high prices for main gas.
Manual ignition mechanism.

All safety, heating and gas control functions are concentrated in the 630 SIT valve

The disadvantages of heat generators are not critical and are a consequence of the maximum simplification of the design and reduction in cost. At the same time, the service life of inexpensive Zhytomyr boilers reaches 15 years, taking into account minimal maintenance.

Floor-standing boilers "Zhytomyr-3"

Explanation. Gas workers really “love” the floor-standing boiler models of the Zhytomyr brand. The design is simple and reliable, malfunctions occur extremely rarely, and accordingly, the technician has less work to do.

The line includes 18 devices - 9 single-circuit models KS-G-SN and 9 heat generators KS-GV-SN with an additional water heating heat exchanger. Main characteristics of boilers:

range of covered powers - 7...60 kW, efficiency - 92%;
the material of the main heat exchanger is carbon or stainless steel, the secondary coil is copper;
burner – tubular micro-flare from Polidoro, combustion chamber – open type;
there is a constantly burning igniter, which is ignited by a piezoelectric element button;
operating coolant pressure – 1.5 Bar, maximum – 2 Bar, permissible pressure in the water circuit – 6 Bar;
recommended temperature schedule - 60...80 °C, maximum - 90 degrees, at 95 °C the overheating sensor is triggered;
removal of combustion products through a traditional chimney with natural draft.

Note. The KS-G-045SN and KS-GV-045SN units with a power of 45 kW are designed for higher coolant pressure: operating pressure - 2 Bar, maximum - 3 Bar.

Design Features

7…16 kW devices are equipped with 630 SIT automation.
Heat generators with a capacity of 22.5…31.5 kW are equipped with 710 MINISIT valves.
Boilers with a power of 40 kW and more are equipped with automatic gas blocks SIT 820 NOVA.

Reference. The latest series of Italian valves 820 NOVA is equipped with a connector for connecting weather sensors and room thermostats. You will find more information on the operation of gas boiler automation in our separate review.

For summer operation of the DHW circuit, the manufacturer suggests looping the supply with the return, maintaining the connection between the boiler and the expansion tank

Advantages and disadvantages

The remaining advantages of water heating devices look traditional for the Atem brand:

simplicity of design and unpretentiousness in operation;
non-volatile – the boiler does not require power supply;
long service life;
models with automatic SIT 820 NOVA can be connected with external control devices - thermostats and weather sensors.

Addition. The new generation of KS-G-SN models with a power of 10...30 kW is equipped with an Atem-Start lightweight ignition system. The start button is located on the front panel of the boiler.

Solid fuel units

In recent years, the Zhytomyr plant has mastered the production of boilers operating on solid fuel. There are 2 lines of heat generators available for the buyer to choose from:

Classic heaters of the AOTV and AKTV series, designed for burning coal, anthracite and firewood.
Pure wood-burning long-burning boilers “Zhitomir-D”.

The first line includes 18 models with a heat output of 12...25 kW with a steel fire-tube heat exchanger. The AKTV series is equipped with a cast iron hob, while the AOTV-V modifications are equipped with a copper coil that heats water for household needs.

Let us list the features and operating parameters of traditional coal boilers:

combustion of fuel and emission of flue gases occurs due to natural draft in the outlet channel;
the air supply and combustion intensity are adjusted manually with a special screw on the ash pan damper or with an automatic draft regulator on a chain (optional);
the secondary copper DHW coil is located in the boiler tank;
the manufacturer declares an absolutely real efficiency indicator - 78%;
operating coolant pressure – 1.5 Bar, in versions with a round body – 1 Bar;
the weight of the device is from 88 to 208 kg, the volume of the fuel chamber is 44–69 liters, depending on the power of the specific model;
burning duration of 1 load of anthracite – 8 hours, firewood – 6 hours;
The highest permissible supply coolant temperature is 90 °C.

Note. The heat generator comes with a poker and a scoop for scooping and cleaning the ash chamber.

In the operating instructions, the manufacturer directly states: solid fuel units are designed to operate in heating networks with natural circulation of water and an open expansion tank. In fact, adding a circulation pump is quite acceptable provided that the coolant pressure does not rise above 1.5 Bar.

The circulation pump in the gravity system is placed on the bypass

In closed heating systems, TT boilers must be used with a buffer tank (heat accumulator). Otherwise, in case of overheating, the pressure in the pipeline network will reach 3 bar, which is why the water jacket of the unit may swell and crack. The warning equally applies to long-cycle heat generators “Zhitomir-D”, whose characteristics are presented below:

the line includes 3 thermal units with a capacity of 12, 16 and 20 kW, the main fuel is wood;
the minimum duration of work from 1 full bookmark is 8 hours;
the firebox volume is increased to 140, 195 and 250 liters, respectively;
boiler tank capacity – 78 l;
unit weight – 200, 250 and 290 kg;
other parameters are identical to heaters of the AOTV series.

Important point. The manufacturer strongly recommends using long-burning boilers in conjunction with an accumulating buffer tank that can hold 0.35–1 m³ of coolant.

The long-burning boiler "Zhitomir-D" has an enlarged firebox, which makes it high

Positive and negative aspects of operation

In terms of ease of use and reliability, Atem TT boilers differ little from other heat generators in the budget segment:

the heat source operates without electricity;
combustion duration and efficiency strongly depend on the quality of the fuel (wood, coal) and operating mode;
cleaning the firebox and ash pan is not difficult; access to the fire tubes is through the front door;
If the operating rules are followed and there is no overheating, the device will last 10-15 years;
you can cook food on AKTV series boilers;
burning wood is a priori more economical than using other energy sources (excluding natural gas in the Russian Federation).

The most important advantage of Zhitomir-D heaters is the large volume of the fuel chamber, which determines the combustion duration. It is very difficult to find boilers of similar capacity among equipment from other brands. The real competitor is the Lithuanian Stropuva 20 kW with a firebox volume of 260 liters, which is significantly more expensive.

For piping a unit with a large firebox, the manufacturer recommends a classic scheme with a buffer tank (heat accumulator)

There is no point in listing the disadvantages inherent in all wood and coal boilers. Let us note the specific disadvantages of Zhytomyr devices:

The low threshold of the maximum coolant pressure does not allow the TT boiler to be safely operated as part of a closed heating system, where the water pressure can reach 3 Bar.
According to the manufacturer's recommendations, the temperature in the return pipeline should not fall below 45 degrees, otherwise condensation will form in the firebox. With natural circulation, it is unrealistic to use a classic piping scheme with a bypass and a three-way valve that protects against cold return.
Manual air supply control does not allow you to implement the optimal operating mode and maintain the desired temperature. The draft regulator only partially solves the problem. Request for the manufacturer: equip 2-3 models with an automation unit and turbocharging.

Video: operation of the Zhytomyr TT boiler

However, the Zhytomyr solid fuel unit can be connected to the closed system of a one-story house, where low water pressure is maintained. In case of overheating, we suggest installing a thermal relief valve, as shown below in the diagram. Read more information on safety valves in the corresponding topic.

When heated to a critical temperature, an additional valve begins to discharge coolant from the system, regardless of pressure. Cold water automatically flows into the boiler

Combined models

In addition to traditional heating equipment, it produces 3 combined series of boilers:

Electric gas heat generators KS-G-SN / KE with a heat output of 10-12 kW.
Units "Zhytomyr-9" burning coal and natural gas. Designation - KS-G-SN / AOTV, power - 10, 12 and 15 kW.
Heating and hot water installation “two in one” KS-G-SN, otherwise – “Zhitomir-10”. The range of models covers the range of 7…30 kW.

Clarification. All types of combination boilers are produced in a floor-standing version.

The line of gas-electric boilers is built on the basis of Zhytomyr-3 units and does not differ in appearance from conventional floor-standing units. The design is complemented by a control unit and an electric heater placed inside the water jacket. 2 types of heating elements are installed - with a power of 4.5 and 9 kW. Important feature: both heating methods can be turned on one by one or simultaneously.

Electric-gas (left) and coal-gas (right) boiler

The coal-gas heat generator “Zhytomyr-9” has the following parameters:

on the left side of the body there is a firebox with a volume of 47 or 70 liters for storing anthracite or firewood;
to the right of the solid fuel chamber there is a gas firebox with a Polidoro burner and an SIT 630 automation unit, a common heat exchanger, and separate smoke exhausts;
efficiency on gas – 92%, solid fuel – 78%, operating water pressure – 1 Bar (Max 1.5 Bar);
work in a closed system is allowed, condition - installation of a safety group with a 1.5 bar safety valve;
duration of 1 coal combustion cycle – 6…8 hours;
There are modifications with a DHW water circuit.

Comment. When operating on coal and wood, the boiler produces less heat than on gas, which is noticeable in terms of efficiency. Example: the KS-G-016SN / AOTV-12 unit in the first case develops a power of 12 kW, in the second - 16 kW.

The operating algorithm is simple: while the coolant is heated by coal, the gas burner does not ignite. When the sensor detects a drop in temperature, the gas supply will open and the right side of the heat generator will start working. The main thing is that the pilot light is lit.

The gas installation “Zhytomyr-10” consists of two separate sections - a boiler furnace and an instantaneous water heater. Burners, safety devices and heat exchangers are completely separated. In fact, the gas water heater and the boiler are combined in one housing. The goal is to increase water consumption for hot water supply to a comfortable level without compromising heating efficiency.

Conclusion

The range of heat generators of the Zhytomyr plant continues to be supplemented with new water heating devices - geysers, atmospheric and turbocharged boilers. It is unrealistic to consider each unit in detail within the framework of one publication, so we limited ourselves to a review of the most popular models. We hope that the brand will continue to maintain its reputation by supplying users with reliable heating equipment.

Removing air pockets before lighting a gas water heater

Before lighting a gas water heater

, it is necessary to fill the heating structure with liquid cold coolant. But just filling with water is not enough. It will either not work, or the degree of heating of the room will be insufficient. A real first start is impossible without releasing the air accumulated in the system. Often modern gas water heaters have a specialized system that automatically releases air when filled. However, its effectiveness is often insufficient: you will still need to manually reset the air jams. Only after this can you launch.

Remove air pockets before turning on the gas water heater

, it is necessary not only from the heating unit, the circulation pump, but also from all heating radiators. The process must begin with batteries - for this, as mentioned above, they are equipped with air vents. They are opened by placing a container underneath. First of all, a light whistle will be heard, which means that air is gradually leaving the system. After removing the plugs, water begins to flow. Then the taps are closed. A similar operation should be done with each of the heating devices.

Valuable advice

To start the boiler , power must be supplied and the heating regulator must be set to the desired operating position. The presence of a weak hum indicates that the circulation pump has started working. Using a screwdriver, you should lightly unscrew the cover of the detected part. However, this must be done before the water starts flowing. If the liquid begins to break through, screw the cap into place. These actions are done a couple of times and after which the air pockets will be completely removed from the system. The gurgling sounds will also disappear and the pump will run quietly.

Specifics

The ATEM brand has invested all its efforts in the development and production of a good device for individual heating. For more than 27 years, the company has been providing heat to its own consumers in the form of gas water heaters “ Zhitomir ”. Since the inception of the first boiler, a very large rebranding has been carried out, the device has received changes from the internal base of spare parts to the external design. Nowadays, the Zhitomir boiler

"is a neat, small-sized block with switching instructions that even a child can handle. The main quality characteristic of boilers of this brand is the reliability and quality of the device. The technical properties of products have also changed with the emergence of recent technologies. Not only these components, but also other facts made it possible for the ATEM brand to acquire the “European Quality Level” award.

But the company did not stop there, the Zhitomir received the “Golden Mark” and “Highest Standard” awards, proving to everyone that they occupy first place in the world market.

Characteristics

Nowadays, products represented by Zhitomir are recognized as the most modern and popular. To understand why this brand itself has gained consumer recognition, we should consider a number of models in more detail. Each individual equipment has a great advantage in comparison with similar devices from other manufacturers. There are disadvantages in Zhitomir boilers, as in any product, but the presence of advantages outweighs the importance, showing that the equipment has many more good qualities.

Gas water heaters “Zhitomir” have a number of advantages, thanks to them they are in great demand on the market.

The heat exchanger of the device is made of steel. Because of this, the water receives the maximum heat that is generated when the gas burns.
The design of the burner is thought out to very small details. Actually, this characteristic helps to increase the productivity of the device, and the level of release of bad impurities is minimal.
Imported automation of each boiler makes it possible to achieve the best characteristics.

Ease of device management. There are no unnecessary buttons or toggle switches.
The design of the equipment is developed according to the latest fashion. The boiler
does not take up much space, and in appearance it is similar to a small bedside table, which fits into any setting.
During the manufacturing process, each individual model goes through several stages of testing according to Western standards. And after completing all tests, he receives a quality document.

Many settings in the Zhytomyr boiler system make it possible to choose a suitable and convenient state for yourself. Specialized sensors, which are also equipped in the system, monitor the device’s safety and trouble-free operation. Taking into account all the positive qualities described above, we can safely say that Zhytomyr

» are perfect for heating privatized houses, and will cope well with their own work in the apartment and in other rooms. It should be noted that not only the bright design and ease of use attract consumers, but also the price issue.

Cost of the boiler " Zhitomir"

"meets the condition "price - quality", and this quality will not hurt your pocket.

How effective are gas boilers Zhitomir and their advantages

Autonomous heating systems are relevant if it is not technically possible to connect an apartment or house to a centralized system.
Gas boilers Zhitomir are quite popular among residents of our country. The products have excellent technical characteristics, are of high quality, and adapted to Russian conditions of use.

In addition, if you look at reviews on the global network, you can understand that many users are attracted by the reasonable price.

Under the brand in question, heating boilers were born 27 years ago. Since then, the products have undergone many upgrades. In order to meet modern requirements and not lose its leading position, the manufacturer is constantly improving and finalizing its product.

General information

The modern gas heating boiler ATEM Zhytomyr has high performance and compact dimensions. The use of foreign automation allows us to achieve optimal performance.

The user has access to many settings, which allows him to maintain the desired temperature in the room. Sensors will ensure that everything works without interruption. Consumers love Zhytomyr boilers, and reviews emphasize the optimal price-quality ratio.

Advice! The cost of a Zhitomir boiler today is 12-45 thousand rubles. Moreover, products at the upper price range have high performance and are capable of heating large areas of premises, suitable for heating multi-storey private houses. For heating a small house or apartment, a modification in the middle price range, up to 20,000 rubles, is suitable.

Floor standing boilers

In turn, a floor heater is divided into:

single-circuit,
double-circuit.

A single-circuit floor-standing gas boiler only powers the heating system. It is extremely economical, thanks to the use of imported automation, which switches the system to energy saving mode as soon as the installation reaches the set temperature.

And at the moment when the temperature drops below a predetermined level, the single-circuit unit lights up at full strength. High-quality components allow you to withstand multiple on/off cycles throughout the heating season.

If you need to not only heat the premises, but also get hot water, you should buy not a single-circuit, but a double-circuit boiler Zhitomir. It has a higher cost, but can perform two options at the same time.

To connect the device, you will need to connect two additional pipes. In the product, the heating circuit operates independently of the hot water preparation circuit.

When choosing a floor-standing boiler in Zhytomyr, you should pay attention to the technical characteristics. So, all floor-standing models have:

Efficiency 92%,
maximum coolant temperature 90 °C,
minimum operating gas pressure 635 Pa.

Moreover, each specific model has:

power, ranging from 7 to 60 kW.
the amount of coolant in the boiler ranges from 14 to 70 liters.
natural gas is consumed in the range of 0.76 - 6.8 cubic meters per hour.
If we consider a double-circuit floor-standing boiler, then its DHW capacity is in the range of 175 - 1400 l/s.

Wall boilers

Just like a floor-standing boiler, a hanging boiler can have one or two circuits. The entire model range has the same efficiency characteristics, maximum coolant temperature and minimum operating gas pressure - 90%, 90 °C, 635 Pa, respectively:

The power range of wall-mounted boilers is from 5 to 15 kW.
The amount of coolant in the boiler is from 5 to 17.5 liters.
natural gas is consumed in the range of 0.56-1.67 cubic meters per hour, depending on the specific model.
The suspended double-circuit boiler has a capacity for the hot water preparation circuit ranging from 160 to 345 l/h.

As you can see, the wall-hung and floor-mounted single-circuit boiler Zhitomir can operate in conditions where the gas in the mains has low pressure. The disadvantages of the products of the brand in question include the low permissible coolant pressure in the heat exchanger:

floor-standing versions have an indicator of up to two kgf/m2,
wall-mounted – up to zero point seven kgf/m2.

For comparison, foreign boiler models can operate with pressures of up to three kgf/m2. This indicates that Zhitomir gas units are more suitable for independent heating systems of a small house, the number of which is no more than two.

Varieties

Nowadays, several types are used Zhitomir For their part, floor products also have divisions into single-circuit and double-circuit.

If a gas water heater

needed only for heating purposes, you need to pay attention to single-circuit models.
They are undemanding, convenient and economical. Equipping a single-stage boiler " Zhitomir " first of all involves foreign components.
Thanks to them, the device can be turned on and off if necessary. And if there is a need, in addition to heating, to have hot water in direct access, you will need to select from dual-circuit options. Due to price demand, double-circuit units are a little more expensive, but they also provide double pleasure to the consumer in their work.

According to their own characteristics, floor-standing boilers mostly have the following similarities:

the highest temperature limit is +90 degrees;
Efficiency is 92%;
gas pressure – 635 Pa.

However, when selecting exactly the model you like, you need to consider its specific characteristics and capabilities.

The same zoning as for floor-mounted boilers is also found in wall-mounted boiler models. They can also be single-circuit or double-circuit. The efficiency of all devices is similar. The same applies to gas pressure.

But it is still necessary to consider their characteristics in more detail:

the power of chimneyless boilers must be at least 5 kW and less than 20 kW;
the thermal fluid in the device is no more than 17.5 liters;
depending on the model that was selected, the network gas consumption is considered; standard – 0.56–1.67 cubic meters per hour;
economy due to imported automation.

For its part, the manufacturer provides a wide range of boilers to choose from, but the Zhitomir -3 KS-G-020 SN model is still in incredible demand. This device differs from its counterparts not only in terms of affordability, but also has clear technical data. The design of the device is designed in a minimalist style; the outside of the boiler looks like a cabinet. It must be placed exclusively on the floor. On the front of the model there is a small flap, behind which the button for turning on and adjusting the device settings is hidden. In this part there is a control window, thanks to which you have to monitor the boiler productivity indicators.

The key package includes a housing, which also includes parts of the heat exchanger. On the outside it is covered with thermal insulation material and a casing made of steel. There are two burners shown: one is the main burner, and the second is the pilot burner. The kit includes a gas duct and an automated gas valve; it is responsible for safety during operation.

If the temperature becomes more than +95 degrees, the shutdown meter breaks the circuit to the valve, and the valve itself automatically closes the gas supply.

Solid fuel units

In recent years, the Zhytomyr plant has mastered the production of boilers operating on solid fuel. There are 2 lines of heat generators available for the buyer to choose from:

Classic heaters of the AOTV and AKTV series, designed for burning coal, anthracite and firewood.
Pure wood-burning long-burning boilers “Zhitomir-D”.

Let us list the features and operating parameters of traditional coal boilers:

combustion of fuel and emission of flue gases occurs due to natural draft in the outlet channel;
the air supply and combustion intensity are adjusted manually with a special screw on the ash pan damper or with an automatic draft regulator on a chain (optional);
the secondary copper DHW coil is located in the boiler tank;
the manufacturer declares an absolutely real efficiency indicator - 78%;
operating coolant pressure – 1.5 Bar, in versions with a round body – 1 Bar;
the weight of the device is from 88 to 208 kg, the volume of the fuel chamber is 44–69 liters, depending on the power of the specific model;
burning duration of 1 load of anthracite – 8 hours, firewood – 6 hours;
The highest permissible supply coolant temperature is 90 °C.

Note. The heat generator comes with a poker and a scoop for scooping and cleaning the ash chamber.

The circulation pump in the gravity system is placed on the bypass

the line includes 3 thermal units with a capacity of 12, 16 and 20 kW, the main fuel is wood;
the minimum duration of work from 1 full bookmark is 8 hours;
the firebox volume is increased to 140, 195 and 250 liters, respectively;
boiler tank capacity – 78 l;
unit weight – 200, 250 and 290 kg;
other parameters are identical to heaters of the AOTV series.

Important point. The manufacturer strongly recommends using long-burning boilers in conjunction with an accumulating buffer tank that can hold 0.35–1 m³ of coolant.

The long-burning boiler "Zhitomir-D" has an enlarged firebox, which makes it high

Positive and negative aspects of operation

In terms of ease of use and reliability, Atem TT boilers differ little from other heat generators in the budget segment:

the heat source operates without electricity;
combustion duration and efficiency strongly depend on the quality of the fuel (wood, coal) and operating mode;
cleaning the firebox and ash pan is not difficult; access to the fire tubes is through the front door;
If the operating rules are followed and there is no overheating, the device will last 10-15 years;
you can cook food on AKTV series boilers;
burning wood is a priori more economical than using other energy sources (excluding natural gas in the Russian Federation).

For piping a unit with a large firebox, the manufacturer recommends a classic scheme with a buffer tank (heat accumulator)

There is no point in listing the disadvantages inherent in all wood and coal boilers. Let us note the specific disadvantages of Zhytomyr devices:

The low threshold of the maximum coolant pressure does not allow the TT boiler to be safely operated as part of a closed heating system, where the water pressure can reach 3 Bar.
According to the manufacturer's recommendations, the temperature in the return pipeline should not fall below 45 degrees, otherwise condensation will form in the firebox. With natural circulation, it is unrealistic to use a classic piping scheme with a bypass and a three-way valve that protects against cold return.
Manual air supply control does not allow you to implement the optimal operating mode and maintain the desired temperature. The draft regulator only partially solves the problem. Request for the manufacturer: equip 2-3 models with an automation unit and turbocharging.

Operating instructions

at the beginning of using the Zhitomir equipment, you need to make a high-quality installation of the product, check the pipes, especially if the boiler is a double-circuit one. Next, the first launch is performed. And then the boiler

part of normal operating procedures. According to the typical scheme, you need to turn on the device, light the wick, then adjust the heat supply. After these steps, you can change the settings to decrease the heating or, conversely, increase it.

At the end of the cold season, the boiler must be turned off for the warm period , because there is no need for it, which will make it possible to eliminate additional waste of the device’s potential. In most cases, after a warm period during the connection period, it is not possible to light the boiler

, the ignition fuse goes out. This may be due to weakened draft, weak gas pressure, or breakdown of the valve responsible for the gas supply.

To correct equipment errors and put the system in order, you should insulate the chimney, check the gas pressure and change the gas valve.

It’s not often that the gas valve fails to start during use. The reasons for this may be broken contacts, poor quality of the pilot burner, or an incorrectly installed thermocouple. Removing damage is simple - you just need to check the contacts. It is worth paying attention to the height of the flame. It must be at least 2.5 cm. You can try reinstalling the thermocouple or changing it completely. After this, check and light the boiler the first time.

As for a number of boiler models “ Zhitomir

", in general, you can hear only the best reviews. Excellent heating and the ability to regulate temperature conditions make it possible to feel comfortable during all cold weather. The simplest mechanism for switching on and setting is just a few knobs and pointers that tell you what needs to be done.

Another special quality that is mentioned in all reviews is the safety of the boilers. If the gas is unexpectedly turned off or the burner goes out, the magnetic block of the gas valve device closes the supply.

Moreover, Zhitomir boilers have a protective system against lack of draft in the chimney system, as well as protection against overheating of the device. In any situation, the gas supply is shut off, which is considered a big difference in the process of troubleshooting. Otherwise, gas water heaters " Zhitomir " are an excellent example of quality and reliability. They are in incredible demand on the world market. Technical properties of boilers " Zhitomir"

“They allow you to make a connection in almost any designated place.
Boilers “ Zhytomyr
” are, first of all, a concern with which you don’t have to think about the costs of heating your home using electric heating devices, and also excellent quality at a price that is affordable for everyone.

Design Features

The main elements of the Zhitomir boiler are:

a housing in which the main components and equipment are installed;
gas burner unit located in the firebox. Here gas combustion occurs and heat flow is released;
recuperative heat exchanger, in which heat exchange occurs between combustion products and coolant;
gas exhaust system, its responsibilities include removing combustion products outside the boiler and releasing them into the chimney.

Construction of the Zhitomir boiler In order to increase the efficiency of heat transfer, the gas boiler Atem Zhitomir 3 has the following design features.

The heat exchanger pipes made of heat-resistant steel have a rectangular cross-section; this device allows you to increase the contact area of the flue gas and the coolant.
The counter movement of coolants was organized, this solution made it possible to increase the efficiency of the heat exchange device to 92%;
To increase the area of interaction between combustion products and the coolant, as well as to prevent the accumulation of soot on the surface of the steel pipes of the ATEM boiler heat exchanger, turbulators are installed. Soot accumulates on the lower surface of the turbolizers, while the pipe walls remain clean. To remove soot, you need to periodically remove the turbolizers and clean them of soot.
Gas double-circuit turbocharged boilers in Zhitomir have a coil of copper pipelines around the heat exchange heating pipes.

Double-circuit gas unit Zhytomyr Atem To organize a stable gas combustion process, a POLIDORO gas burner device is used. Its distinctive feature is a single-stage atmospheric burner. The edges of the burners themselves are made of heat-resistant steel, which allows you to maintain the combustion mode at different gas supplies to the firebox. Even at low gas consumption, the heating of the edges is sufficient to maintain stable combustion.

The gas supply mode is regulated by the EUROSIT gas valve. This device automatically switches the gas supply to the burners depending on the temperature of the coolant. The user independently sets the temperature of the coolant, focusing on the temperature in the open air. As the ambient temperature decreases, the temperature of the coolant increases.
