To create comfortable conditions inside a building, it undoubtedly needs to be heated in winter and cooled in summer. The supply of heat to apartment buildings is ensured by the operation of the central city heating system.
In the absence of one, residents use an electric or gas boiler. The latter can only be installed if there is natural gas within walking distance of the premises. Typically, the choice of equipment brand and its installation occurs at the design stage and depends on many factors. And the dimensions of a gas boiler are determined based on the area of the room in which it will be installed.
How to choose?
Experts and installers call the area of the house the main initial parameter influencing the purchase of equipment. It is believed that the power of the unit should be selected at the rate of 1 kilowatt per 10 square meters of space. Here the size of the gas boiler is important, but is perhaps of secondary importance.
Professionals advise you to take note:
- number of residents in an apartment or private house;
- building materials from which the walls and roof are constructed;
- presence or absence of a basement;
- installation of heated floors or light floor coverings;
- weather conditions in the building area;
- number of window openings and quality of installation of double-glazed windows;
- type of window glazing;
- number of floors
Recommendations for choosing a model and its power
According to the installation method, there are 3 types of boilers: floor-mounted, wall-mounted and parapet. Floor-standing ones are rarely used in apartments because they are less compact, require more area around them, and are not so convenient for connecting communications. The best solution for an apartment is a wall-hung gas boiler; most of these models correspond to the size of wall-mounted kitchen cabinets, have an excellent design and fit harmoniously into the kitchen. We recommend choosing a wall-mounted model.
One of the best modern wall-mounted models is Baxi ECO4S 24 F.
Parapet boilers are installed anywhere below the plane of the window sill and are distinguished by the fact that they simultaneously serve as a radiator, at the same time heating the room in which they are located. The chimney for parapet boilers is exclusively coaxial and, as a rule, is included in the kit.
There are single-circuit and double-circuit models. The former are focused only on heating, the latter are equipped with an additional hot water supply circuit. Therefore, if the apartment already has or is planning to install a hot water boiler, a single-circuit model is sufficient. If you want to heat hot water using a boiler, you need to study all the advantages and disadvantages of dual-circuit models.
The power should be chosen after deciding on the model, since in most cases the same model is produced with different thermal power. Calculating the minimum required power is simple: for every 10 m2 of apartment area, 1 kW of boiler power + 15-20% reserve is required. For example, for an apartment with an area of 120 m2, 16-20 kW will be quite enough. If the boiler is not equipped with a modulating burner (with the ability to adjust the flame), you should not go overboard with the boiler power, as this will lead to frequent clocking and faster wear.
How to accurately calculate the required boiler powerIndividual calculation, formula and correction factors
Boiler room area
According to regulatory documents, the size of the room for a gas boiler is determined depending on the power of the equipment. This is the indicator that determines the degree of heating of the room. Therefore, it is better to entrust its calculation to professionals. For the smooth functioning of the heating system, a specialized company develops a design and technical specifications. You can independently select the room for installing the boiler and its brand, but you cannot connect the boiler without agreement with the necessary structures.
Depending on the power of the gas boiler, the overall dimensions of the room should provide the following area:
- 7.5 m2 - with the main characteristic of 30 kW;
- 13.5 m2 - with a power within 60 kW;
- 15 m2 - more serious boilers with an output of up to 200 kW.
Controls, automation, protection levels
The boiler must be fairly easy to use, have clear controls, be equipped with the necessary functions to optimize operation and several degrees of protection against emergency circumstances.
Leading manufacturing companies are constantly improving their models, thereby creating competition between brands, so new developments are constantly appearing.
Thus, modern boilers can be equipped with the following options:
- Flame modulation in heating and water heating modes. The flame level is electronically regulated, ensuring smooth starts, which is especially important for models with instantaneous heating of DHW water. The automation independently selects the height of the flames depending on the set temperature and the specific current water flow. In some models, the last 5 degrees to the set heating temperature of the heating system are gained at a reduced combustion intensity. This allows you to make the operation of the device smoother, reduce the number of starts, and therefore increase the service life of the equipment.
- The smooth electronic ignition system pursues similar goals. When, after the minimum flame appears on the burners, it gradually grows to the specified combustion intensity within 30 - 40 seconds. When the boiler operates as a water heater, this option does not apply - what is important here, on the contrary, is the speed of heating the water to a given level.
- Weather-compensated boiler automation. This innovation, when installing an external street sensor, allows the equipment to monitor the level of external temperature and make adjustments to maintain an optimal microclimate in the apartment. More advanced equipment of this type also has an automatic self-adaptation function. Electronics not only compares graphs of changes in external and internal temperatures, but also conducts an analysis, making adjustments to the operation of the boiler, which leads to maximum comfort and significant gas savings.
- Pump post-circulation. A useful function that, when a room thermostat is installed, can significantly reduce energy consumption. Once the required heating temperature has been reached in the heating system, the boiler turns off and the pump continues to operate for another three minutes. When it is necessary to resume operation, both the boiler and the pump are started simultaneously.
- Naturally, all modern electronically controlled boilers allow you to accurately set the temperature in both the heating circuit and the DHW. In addition, some models provide two switchable ranges in heating mode - for conventional radiators and for heated floors.
- The electronics allow programming of the boiler operation for a certain period of time, with the programs being stored in memory for reuse.
- Any gas equipment has several degrees of protection - in case of insufficient draft, in case of heater extinguishing, in the absence or insufficient water pressure in the circuits, etc. In addition, modern models are equipped with other safety functions. So, if the temperature in the circuits drops to +5 degrees, the boiler will start on its own to bring the heating level of the coolant and water to a safe value, in order to avoid freezing. In addition, some control systems also monitor the condition of the boiler elements. If the device has not been used for more than a day, the processor will turn on the pump for a short time or switch the position of the three-way valve back and forth. This allows you to avoid blocking or “sticking” of these units and extends their service life.
- Control panels can have push-button, touch or electromechanical control, and are equipped with dial or digital indicators of temperature and pressure in the system.
Product installation requirements
The main indicators that determine the possibility of installing a heating device in a particular room are:
- preventing combustion products from accumulating in the room;
- no smoke;
- prevention of emergency situations including fires.
When a gas boiler is operating, the dimensions of the boiler room or other room with equipment are regulated by SNiP. The same standards establish fire safety, which is ensured during installation in compliance with the following rules:
- The distance from floor to ceiling should not be less than 2.5 meters.
- The installed hood carries out three air exchanges.
- It is necessary to have a window with an area allowed by the standards.
- The door must be equipped with a lower grille or replaced with another sample with a gap to the floor of 0.025 m2.
It is not permitted to dismantle a previously installed door and replace it with arches or curtain structures.
How much gas is needed for heating?
Experts in the field of heating equipment calculate the gas consumption for a specific room and recommend a suitable gas boiler. The size of the unit, of course, affects the power, but does not always affect the amount of gas processed. According to the existing formula, the required parameter is determined as:
V = Q / (Hi x ƞ), where
Q—calculated thermal power, kW/h;
Hi—heat of combustion, kW;
Ƞ—efficiency factor.
Thus, if:
- the average boiler power, usually taken as power divided in half, is 5 kW per hour;
- the specific heat of combustion per 1 m2 is determined to be 0.1 kW (for example, for a house with an area of 100 square meters it will be equal to 10 kW);
- The efficiency, according to the equipment passport, is 95%,
then V = 5 / (10 x 0.95) = 0.53 m3/h.
If we calculate that the heating season is 200 days, and more specifically, 4800 hours, then the amount of gas will be calculated as follows:
0.53 x 4800 = 2544 m3.
Fuel type: electric, gas, solid fuel or liquid fuel
For a home of about 100 square meters, any of the fuel types described below may be suitable. The choice should be made based on whether gasification was carried out in your area of residence, how accessible this or that type of fuel will be, whether there is enough space in the house for a large boiler or whether a compact one is required.
Gas.
The most affordable and popular type of fuel. It can be mainline or liquefied. Gas fuel is inexpensive, produces high heat transfer during combustion, and produces a relatively small amount of combustion products. Gas boilers are widespread. Many manufacturers have several series of such heating equipment (for example, Protherm Bear or Jaguar, Vaillant turboTEC or ecoTEC). There are floor and wall variations. Gas heating boilers for a house of 100 sq.m. have different prices (from 30,000 rubles and above), economy class, middle class and premium boilers that have additional functions and an increased service life are available for purchase. The efficiency of such boilers is on average 88-93%. Many service organizations and craftsmen service gas boilers, which simplifies repairs and finding spare parts.
Electricity.
Electric boilers are often used as a boiler for heating a house of 100 m2. Electricity is more expensive than gas, but it is an excellent option in areas where there is no gas supply. Modern electric boilers are affordable, but fuel costs can reach 5-10 thousand per month. Also, electric boilers for a 100 m2 house are very compact and low noise. As a rule, electric heating boilers are used for temporary residence in a country house.
Solid fuel.
These are coal, fuel pellets, firewood. Today, the share of houses heated with solid fuel is only 5-15% (in different regions). This heating equipment has a number of disadvantages: the need to prepare and store fuel, unstable heat transfer, the inability to work without the constant presence of a person, rapid contamination of the boiler, etc. In remote areas, solid fuel boilers for heating 100 m2 houses are still successfully used, since there is no gasification and stable electricity. To operate a solid fuel boiler, you need to systematically add fuel, but many modern models have an automated supply.
Liquid fuel (diesel, kerosene, fuel oil, etc.).
Quite efficient floor-standing boilers with good efficiency, which are not very common (about 10% of all boiler units) due to the need to install a separate boiler room. Also, liquid fuel heating boilers require a supply of fuel, which must be stored in a special tank.
Classification of gas boilers
Heating equipment is divided into five types according to the raw materials used: gas, electric, solid fuel, liquid fuel and combined.
Whether it is a gas boiler of minimal size or a large, advanced model, it is classified according to many parameters:
- Installation location: floor, wall.
- Functional purpose: single- and double-circuit.
- Burner type - atmospheric, turbocharged, diffusion, complex.
- Ventilation - forced or natural.
Small-sized wall-mounted gas boilers, which are mounted within the kitchen, are suitable for apartments. When building private houses, it is better to separate a small room, use it as a boiler room and purchase floor-standing devices.
Power control function and burner type for a boiler for a house 100 m2
This opportunity is relevant for gas boilers.
- Single-stage
is the simplest option, allowing the heating unit to operate only at 100% power. - Two-stage
- provides two modes: 100% and 50% power. - Modulating
is the most modern and economical type of burner. Makes it possible to regulate power in steps of several kW (for example, switching occurs at 20%, 40%, 60%, 80% and 100% of power). In this case, the boiler operates constantly, no clocking occurs. Optimal gas consumption is achieved.
Baxi Nuvola-3 Comfort 240 Fi
The Italian-assembled model has a lot of positive aspects, including:
- wall mount;
- the area of a residential building or apartment allowed for heating is up to 220 m2;
- presence of a display;
- possibility of removing the control panel;
- operation on natural gas supplied through a main pipe or from a cylinder in a liquefied state;
- closed combustion chamber type.
In terms of overall dimensions, a gas boiler of this brand is considered quite large and heavy. After all, its weight is 70 kg, its height is close to a meter, its depth is half a meter, and its width reaches 60 cm.
A special feature of the model is 2 separated heat exchangers: the primary one is made of copper, and the secondary one is made of stainless steel. The temperature of the heating system is regulated by the Baxi boiler from 40 to 85 degrees. Net power starts from 10 kW and can increase by 2.4 times.
Since heating equipment from this manufacturer has a high price, buyers usually ask for clarification of the advantages of this product over others. In this case, experts note:
- Adaptation of the model to pressure surges in a gas pipe.
- Convenient ignition.
- Availability of storage boiler and expansion tank.
- Complete with an energy-saving circulation pump.
- Setting up operating parameters for a weekly period.
- The presence of automation that connects to an external temperature sensor and regulates parameters.

Wall-mounted gas boilers: detailed description, technical characteristics, varieties and manufacturers
A wall-mounted gas heating boiler is perhaps the main purchase when supplying gas to a private home. Due to its light weight and compact size, this device will fit into any environment, be it a kitchen, bathroom, pantry, attic, basement or separate boiler room. As a rule, due to restrictions on size and power, wall-mounted gas boilers are capable of heating a living area of up to 500 square meters, which is enough for most urban and suburban housing projects.
Characteristics of wall-mounted gas boilers
All gas boilers can be divided into several groups depending on their inherent features according to various parameters:
Number of circuits
There are wall-mounted gas boilers with one or two heating circuits. Single-circuit heating boilers are capable of heating only one branch - the heating branch, while double-circuit wall-mounted boilers allow you to simultaneously heat the house and heat water.
Combustion chamber view
Wall-mounted gas boilers with an open combustion chamber provide energy independence, but require a separate room with good ventilation for air intake. This problem can be avoided by devices with a closed combustion chamber, which require a coaxial chimney and a network connection to operate.
Total heating power
As a rule, single-circuit wall-mounted heating boilers have less power than double-circuit heating boilers, and their efficiency can be calculated using the formula 10 square meters of room per 1 kW of boiler power. For double-circuit wall-mounted boilers, the planned volume of hot water consumption must be added to the calculation formula.
Gas consumption
The more powerful the wall-mounted boiler, the more gas it will consume. Do not forget that in the spring-autumn period the heating can be turned on only at night, which allows you to reduce consumption by 3-4 times compared to winter.
Performance
The performance of wall-mounted gas boilers is characterized in volumes of water heated to a certain temperature in one minute, and is measured in liters per minute. No less important is the maximum heating temperature and the ratio of gas costs to the volume of heated water.
Dimensions
Typically, wall-mounted gas heating boilers are quite compact and are no larger in size than a washing machine. So, the height of the boiler is from 65 to 85 centimeters, and the weight is in the range of 30-40 kg.
Installation of wall-mounted gas boilers
All wall-mounted gas boilers consist of:
- Control and automation unit
- Circulation pump
- Expansion tank
- Gas-burner
- Heat exchanger
- Fan for forced removal of combustion products
- Safety group - safety valves, thermometer and pressure gauge
Of course, manufacturers strive to make improvements and modifications to the design, so it’s worth sorting out all the elements in order.
Control and automation unit
In wall-mounted gas boilers this is one of the most important elements. He is responsible for the operation and safety of all equipment. Pressure, draft, temperature, network voltage - all these parameters are measured and adjusted by controllers. We can say that the control unit is the brains of the heating boiler.
Circulation pump
The pump creates conditions for the free flow of water in the heating system. Usually, up to two pumps are installed that have a post-circulation mode - after the boiler is turned off, hot water continues to circulate for some time to avoid boiling inside the pipes.
Expansion tank
The main purpose is to retain excess water when heated and thereby reduce pressure in the pipes. A very important component of wall-mounted gas boilers, responsible for the overall safety of the system.
Gas-burner
The gas burner is the heart of a gas boiler. It is she who is responsible for igniting and maintaining the gas combustion process. There are different types of burners:
- Single position – always operates in “one position” at 100% power
- Two-position - there is an option to operate at 100% and 50% of maximum power
- Modulated - allow you to precisely adjust the desired power, thereby saving gas.
Heat exchanger
The heat exchanger of a wall-mounted gas boiler performs the function of transferring heat from the burner to the coolant - water. Typically made of copper or stainless steel. Each heating circuit requires a separate heat exchanger.
Fan for forced removal of combustion products
Performs the function of taking in fresh air and removing exhaust gases. Installed only in turbocharged wall-mounted gas boilers.
Safety group - safety valves, thermometer and pressure gauge
Safe use of gas equipment is impossible without systems for measuring and adjusting temperature and pressure. The collected information is transmitted to the front panel and to the automation unit, from where commands are sent to the automatic safety valves.
Advantages and disadvantages of wall-mounted gas boilers
Advantages of wall-mounted gas heating boilers:
- Compactness. Wall-mounted gas boilers take up significantly less space than floor-standing counterparts.
- No need to clean the boiler from soot and soot
- No need for a separate brick-lined chimney
- The most economical models are wall-mounted
- Does not require a separate room
Disadvantages of wall-mounted gas heating boilers:
- The quality of the fuel and coolant is very important. When using low-quality gas or water, the entire unit may fail
- Limited in maximum power by its size
- It is extremely difficult to repair on your own. Due to its complex and compact design, a wall-mounted gas heating boiler can only be repaired by a specialist with tools and training.
Choosing a wall-mounted gas boiler
When choosing and purchasing a gas boiler for the wall, you need to evaluate the following parameters:
- Device power.
You can calculate it using the formula 10 sq.m. premises = 1 kW boiler power. - Number of gas boiler circuits .
See above for the number of circuits. - Boiler requirements for water and gas.
Each manufacturer has its own standards for the fuel used; you can find out from them directly upon purchase. - Availability of a smart thermostat.
Timely blocking of the boiler in the event of a malfunction is the key to safety in the house.
Schemes of heating systems with natural and forced circulation
Manufacturers of wall-mounted gas boilers
We invite you to familiarize yourself with the equipment of market leaders, namely:
- Navien
A proven Korean equipment supplier, whose history dates back to 1978. Today the company has representative offices in the USA and Russia. A distinctive feature of wall-mounted boilers of this brand is their unpretentiousness in operation (lower requirements for the quality and pressure of water and gas).
- Arderia
Arderia is a brand resulting from the joint work of Russian and Korean engineers. Taking the line of wall-mounted gas boilers from the Daesung company as a basis, the Russians modified the design, adapting it to the Russian climate. The main feature of the products of this campaign is high efficiency and efficiency when burning fuel due to the features of heat exchangers (one boiler contains two heat exchangers made of different materials) and direct current charging.
- Bosch
The famous Bosch brand from Germany, which has become famous for producing a wide range of high-quality household appliances. Wall-mounted gas boilers of this brand are characterized by increased comfort and safety of operation. These silent and powerful wall-mounted boilers of the AAA segment can even cope with gas heating of a large private house.
Bottom line
We hope we have helped you with advice on choosing and purchasing a wall-mounted gas heating boiler. Finally, we’ll give you a couple more tips:
- “The miser pays twice” - this rule also applies to gas equipment. It is better to spend a little more money when purchasing to avoid problems and unplanned expenses in the future.
- You can only trust trusted manufacturers that have certificates of compliance with safety standards.
- Always keep on hand the telephone number of the service that repairs wall-mounted heating boilers of your brand. Being left without heating for a long time in winter due to equipment failure is an extremely dubious pleasure.

Buderus Logamax UO72-18K
One of the budget options for German double-circuit gas boilers. The dimensions of this sample are much smaller than the previous Italian bestseller. Dimensions of 700x400x300 mm reduce the weight by 2 times, which allows you to look at the boiler from a different angle and find additional advantages in it in the form of:
- Safety systems that prevent emergencies due to a drop in pressure or an extinguished flame.
- Power 18 kW.
- Heating temperatures from 40 to 82 ˚С.
- Economical.
- Ease of use and settings.

Some consumers complain about the poor quality of the plastic latches and the insufficiently detailed instructions for the unit regarding the recognition and repair of minor breakdowns.
Ariston
This is perhaps the most popular foreign brand, which has two possible options for installing a gas boiler. The manufacturer's floor-standing models are larger in size than wall-mounted ones. The same trend can be seen in the cost of equipment.
Thus, a copy from the expensive Unobloc GPV 24 RI Met series must be installed on the floor. Of the main technical characteristics you need to take into account:
- open combustion chamber;
- atmospheric burner;
- electronic ignition;
- heat exchanger made of cast iron;
- power 26.6 kW;
- presence of an expansion tank;
- possibility of connecting a boiler;
- dimensions 850x450x665 mm.
The cost-effective wall-mounted sample CLAS X SYSTEM 15 CF NG is tuned to Russian realities both in terms of fruitful work and in terms of cost.
If we simply characterize the product, we can note its reliable operation for the time declared by the manufacturer. After the end of the warranty period, it is quite difficult to achieve uninterrupted operation from an unsuccessful model. However, many buyers do not encounter problems for a long time, and therefore recommend a budget boiler to friends and acquaintances.
Step-by-step instructions for obtaining permission to install
We go to the local gas supplier, fill out and submit an application there for the installation of a gas boiler in the apartment. After some time, they must issue a conclusion on the technical feasibility of installing and connecting the boiler unit. Now it is necessary to obtain a conclusion about the proper state of ventilation. The address of the organization involved in checking ventilation ducts can be found in the fire inspection authorities or in the housing and communal services (you can usually find out the addresses of other necessary organizations here). If the ventilation is in order, we get a permit; if it does not meet the requirements, we get a conclusion on the required list of works, carry them out and again submit them for inspection to specialists who will issue a permit. We order a project from the local Gorgaz or any design bureau that has the right to carry out such work. At this stage, it is already necessary to decide on the model of the gas boiler and meter, since the project is drawn up in accordance with their technical characteristics. It is quite difficult to make changes to the project, and after it is signed, it is completely impossible (a new one is created). It is not necessary to buy a boiler and meter yet. We head to the local heating network and submit an application to refuse central heating (and, if necessary, hot water supply). You need to come here with a ready-made renovation project (installation of a gas boiler). You will also need: title documents for the apartment; technical certificate of the premises; written consent to disconnect all family members. We turn to gas workers (“Gorgaz”) and conclude an agreement for boiler maintenance. We also submit the project for approval; after its approval, you can carry out the installation of an individual heating system yourself or entrust the work to Gorgaz. At this stage, disconnection from the heating network is carried out, a boiler and gas meter are installed
Please note that the work is carried out outside the heating season, since it is necessary to drain water from the heating system of the entire house. The boiler is installed without connecting to the gas main. After completing all the work, you must contact Gorgaz to obtain an acceptance certificate for the conversion work
Gas workers will also connect the boiler to the gas main, carry out the adjustment and first start-up of the gas boiler, and put the appropriate stamp in the model passport (without this, the warranty on the boiler unit will be invalid).
Viessmann Vitogas 100-F 29
This sample is considered the cheapest of the expensive models of the Viessmann brand. The price in this case is reflected in the quality and provides reliable heating in any conditions.
Non-volatile boiler type, floor installation, high efficiency, noiselessness, low fuel consumption - this is the minimum of the many advantages available. The manufacturer positions the boiler as a good option for providing heat with a long service life and full automation of most processes.
The average dimensions of a floor-standing gas boiler allow its installation not only in a separate boiler room, but also in the kitchen, of course, if there is free space. Professionals call weather-adjusting automation, an electronic control system and an additional electronic cascade control unit the advantages of the unit.
Efficiency - efficiency factor
Efficiency directly depends on the type of boiler and the fuel it consumes. The higher this indicator, the better.
Electric boilers have the highest efficiency - up to 99.5%. Gas models on average produce 88-95%, liquid fuel 85-90%, and solid fuel ones take last place - their average efficiency is 81-88%.
You might have seen on sale with efficiency above 100%. They do exist, but in this case the efficiency is shown relative to standard models of similar power. Condensation models, which also receive thermal energy from condensate, have an efficiency above 100%. Such boilers are expensive, but they are economical in terms of fuel consumption.
Navien
When the brand is important to the consumer, and the price is high enough, Korean heating equipment will come to the rescue.
The advantages of the Navien product line, in addition to the affordable price, are:
- A specialized device in the form of a chip that monitors and regulates voltage drops.
- Possibility of working with low pressure.
- Remote control with display.
- Automatic power control.
- Compactness.
- A two-circuit system that allows, in addition to heating, hot water supply.
Interesting models include wall-mounted gas boilers for a private home, the size of which does not exceed 240 m2. Installers call Navien Deluxe 24K one of the most attractive examples in terms of cost. Unlike more expensive models, the boiler mostly performs the same functions as branded devices, but for less money. Technical characteristics that can evoke positive emotions are:
- dual-circuit operation of the device;
- closed combustion chamber;
- temperature inside the system up to 80 degrees;
- electronic control;
- the presence of a circulation pump;
- ability to accept natural liquefied gas.
Comfortable operating conditions are achieved due to automatic ignition, the presence of a thermometer, remote control and room temperature meter. Security is ensured by 6 additional options. The compact size of the gas boiler - 440 x 695 x 265 and low weight make installation and subsequent maintenance of the presented model easier.
"Conord"
The manufacturer talks about the competitiveness of its product and at the same time warns buyers about special installation rules:
- On mandatory approval of the project with specialized organizations.
- During installation work, it is necessary to achieve uninterrupted water circulation by placing the lower pipe below the level of the radiators.
- When connecting to a heating system by welding, it is recommended to leave the threaded connections for subsequent dismantling for repair purposes.
- The equipment must be installed on a fireproof covering that exceeds the dimensions of the gas boiler by 50 cm in all directions.
- It is necessary to ensure the removal of combustion products through vertical risers or maintaining a slope when they are horizontal.
In addition, the general installation rules approved for all types of heating equipment cannot be neglected.
Experts call the floor-mounted single-circuit boiler KSts-G10 a popular model of domestic production. Among the advantages of the model, experts call the low cost and note a number of additional bonuses in the form of:
- Efficiency 90%;
- thermal power from 10 kW;
- maximum gas flow 1.2 m3/h;
- light weight;
- the presence of automation capable of modulating the flame;
- permissible pressure up to 5 atmospheres;
- ease of installation and maintenance.
A special feature of this specimen is also called the acceptable dimensions of a gas boiler for a private home. However, installation of equipment of this kind in an apartment is not permissible due to the impossibility of hanging the sample on the wall.
ZhMZ
The plant produces 5 series of gas boilers: “Beetle”, “Comfort”, “Universal”, “Economy” and “Economy Plus”. The last two series are represented by 3 options, and the popularity of the AOGV-17.4-3 model is very high due to the excellent combination of affordable equipment cost and long-term reliability. As the name suggests, the power of the unit corresponds to 17.4 kW, and the area to be heated should not exceed 150 m2. A floor-standing single-circuit boiler does an excellent job of heating a small private house. The boiler's weight of 47 kg and dimensions of 1200 x 456 x 458 mm do not cause any particular difficulties during transportation and installation of the product.
The brand has proven itself due to its use in boilers:
- technology for seamless welding of the heat exchanger tank;
- automation units that ensure safety and ease of use;
- a simple burner that can be replaced and is not difficult to clean;
- overheating sensor;
- room thermostat.
What is a single-circuit heating boiler?
A single-circuit heating boiler is equipment with a built-in heat exchanger, designed for stable heating of non-residential and residential premises of any size.
The design is compact, has good efficiency and is easy to maintain, which is explained by the design features of the unit.
A high degree of automation allows the device to be used in various modes.
