• High cost of equipment and spare parts.

NOTE!

All users note the high cost of equipment from European manufacturers, which can be considered a common feature of such products.

Varieties

It was already mentioned above that boilers from this manufacturer can be chimney and turbocharged. In addition, they are divided according to several other criteria. Boilers can be double-circuit or single-circuit. Their fundamental difference lies in the number of contours, as the name implies. That is, a single-circuit boiler is responsible primarily for heating the room, and a double-circuit unit heats water for both heating and domestic needs. But if you have a single-circuit boiler, the problem of hot water can be solved by installing an indirect heating boiler.

Boilers can also be of a traditional type or condensing type. The principle of operation of a traditional boiler is quite simple - combustion products heat water and evaporate through the chimney. But the principle of operation of a condensing boiler is much more complicated - in this case, the combustion products condense, that is, turn into liquid. The design of such a boiler itself is much more complex. Also, such a boiler has a coaxial chimney, which consists of two pipes of different diameters that are inserted into one another.

One of the most famous is the Viessmann Vitopend 100 WH1D 263 boiler model. This option has quite decent power - about 32 kW. This is a double-circuit boiler, which is used both for heating the house and for supplying hot water for domestic needs. The combustion chamber of this boiler is closed. The tank of the device has a large volume - 10 liters, as well as a powerful circulation pump with a safety valve. Such a boiler is guaranteed to heat the water to almost 80 degrees, and in a very short time. The price for this boiler varies within 45 thousand rubles.

Another gas boiler is the Viessmann Vitopend 100 WH1D 513. The heat exchanger of this boiler is divided into two parts. One of them is made of high quality copper, and the second is made of stainless steel. Such separations are called “primary” and “secondary” heat exchangers. The power of this unit is high - 33-35 kW. This is a single-circuit boiler that is designed for heating. The approximate price will be 36-38 thousand rubles.

The next model is the Viessmann Vitopend 100-W A1HB boiler, which has a power of 24 kW. The boiler is single-circuit. This is a simple and convenient model with a high-quality chimney system, small dimensions and low noise level. The boiler is capable of heating water up to 80 degrees. The chimney diameter is 60/100. This is an excellent choice for heating a private home with a decent level of efficiency. The price for such a boiler will be approximately 39-40 thousand rubles.

Peculiarities

The Viessmann Vitopend 100-W A1JB010 model has the following overall dimensions - 400x725x340 mm (WxHxD), while the weight is 32 kg. Installation is carried out on the wall, which saves space in the room.

Principle and main operating parameters.

The convection type of device involves the generation of heat from gas combustion, while the boiler operates on natural gas (methane, consumption 2.77 cubic meters per hour) and liquefied gas (propane-butane mixture, consumption 2.09 kg/hour).

To obtain the declared power of 24 kW, the pressure of natural gas must be at the level of 13-20 mbar, and the permissible pressure of liquefied gas - 37 mbar; when these parameters decrease, the thermal power will also drop. ExpertKotel.ru reminds that most often in domestic networks the pressure is 12-20 mbar. The efficiency of the heater, with such indicators, is at an excellent level and equals 91%.

Heating of water, coolant in pipes

. This boiler is capable of producing 11.2 l/min of hot water (t=30°C). The coolant temperature is 40-80°C, and in the hot water supply circuit - 35-57°C.

Circulation pump

necessary for the circulation of coolant (water, antifreeze) through the heating circuit, it is a mandatory component of a closed heating system; in our case, the pump is included in the kit.

Expansion tank

compensates for the expansion of the coolant in the pipes during heating and releases it back into the system during cooling. This maintains constant pressure in the circuit.

Fuel economy

Burner flame modulation

makes it possible to smoothly regulate the intensity of the fuel supply and reduce/increase the flame, which allows you to reduce gas consumption.

Auto-ignition (or Electric ignition)

allows the Viessmann Vitopend 100-W A1JB010 to start and extinguish the burner according to an algorithm when necessary, which saves fuel.

Gas consumptionValueNaturalLiquefied

Management and control

The Viessmann Vitopend 100-W A1JB010 gas boiler is electronically controlled, equipped with a display and has a port for connecting additional devices (most often thermostats, programmers, room remote controls, etc.). The advantage of the electronic system is that it does not require the constant presence of a person and allows significant fuel savings (as described above), the disadvantage is that it is more complex than a mechanical one and depends on voltage drops (it can fail during surges).

Thermometer and pressure gauge

. A thermometer is necessary to monitor the temperature of the coolant in the boiler, and a pressure gauge shows the pressure of the coolant; this is an important parameter, because exceeding it can lead to breakdown of individual parts or the system as a whole.

Protection systems

Gas control

- a useful and necessary function of the burner; if the flame goes out for any reason, it stops the gas supply automatically.

Safety valve

"Viessmann Vitopend 100-W A1JB010" protects the system from excess water pressure in the circuit in excess of the maximum permissible norm.

Air vent

. An important element of the safety group, when the pressure in the heating system increases, the air vent automatically releases excess air, most often working together with a safety valve.

Coolant freeze protection

independently turns on the burner for a short time, provided that the water temperature drops to a critical level and there is a risk of heating defrosting. It is worth remembering that for this there must be gas and electricity.

Pump blocking protection

activated when the boiler installation is idle for a long time, in this case the pump turns on for a while and turns off itself. This is necessary in summer when the heating circuit is not activated.

Coolant overheat protection

turns off the burner if an abnormal water temperature value is detected.

Connection

• The connecting size for the gas pipe is 3/4″.
• Hot water supply - 1/2″.
• To connect the heating circuit - 3/4″.
• The diameter of the coaxial chimney is 60/100 mm.

To connect the power supply, a 220 volt network with a pure sine wave and grounding is required.

Turning on the gas boiler, first start: instructions

Do you want to install individual heating in your home? Have you already installed and connected gas equipment? Great, then all that remains is to figure out how to turn on the gas boiler. Do you think it’s enough to insert the plug into the socket and select the temperature? No matter how it is. Before this, it is necessary to bleed the air and fill the system with water. You will find instructions with the sequence of actions in our article.

Other information

Note! Hot water capacity – up to 14 liters per minute. Gas freezing during cold periods is prevented thanks to new chimney designs.

A water heater with a volume of up to 50 liters complements the design of the Vitopend 222 model. Such products operate at a power of up to 10.5–24 kW, this is a kind of technical standard.

The most economical of all water heating boilers is the 100-F. The surfaces responsible for heating are made of special gray cast iron of the highest quality. Addition – lamellar or flake graphite. The thermal intensity of the boiler itself remains small.

The equipment is used to heat small rooms and water, since the power will be only from 29 to 140 kW. This option is also relevant for installation in utility rooms. The main thing is to remember which code is assigned to which error.

What series and models are floor-standing

There are 4 main series of Viessmann floor standing boilers:

• Vitogas. Extensive series of boilers with power from 29 to 420 kW. All models have a cast iron sectional heat exchanger and an atmospheric burner with partial mixing.
• Vitocrossal . A series of boilers with a total power from 2.5 to 1400 kW. Equipped with a heat exchanger having a smooth inner surface with a self-cleaning function. can be connected to a long chimney, allowing them to be used in tall buildings.
• Vitola . Heat exchanger with self-cleaning capability. The boiler power is 18-1080 kW. It is possible to replace the burner and switch to diesel fuel.
• Vitorond . Boilers that are similar in design to the Vitola series with minor differences.

IMPORTANT!

The ability to operate on liquid fuel does not increase the capabilities of the boilers, since for a full conversion it is necessary to organize the correct supply and storage of diesel fuel, which is very difficult and costly.

In addition, there is a line of floor-standing boilers of the Vitodens 222-F series, the remaining models of which are wall-mounted .

The cost of these models is very high, so only Vitogas series boilers are common.

Overview of Viessmann Vitopend boilers with closed and open combustion chambers

If you have an atmospheric boiler with an open combustion chamber, then its operation will be characterized by natural draft. Some consumers deliberately refuse such equipment, and here's why. For fuel combustion, air will be taken from the room where the equipment is located. Exhaust gases will enter the chimney under the influence of natural draft.

Such boiler equipment Viessmann Vitopend 100 requires intensive ventilation of the room, which is not always possible or profitable. The closed chamber is complemented by a smoke removal system. It has a built-in fan-exhaust fan, which is responsible for removing combustion products and draws in air, which is so necessary for the functioning of the boiler.

The operating principle is built around a coaxial chimney. The Viessmann Vitopend 100, which has a closed combustion chamber, has one important advantage in that the device does not burn oxygen in the room. Additional air from outside is used to burn the fuel. For such boilers, there are coaxial chimneys, for which you will have to make a hole in the wall. This, in turn, can become a stumbling block when choosing such equipment, especially for consumers in the northern regions.

Summary and evaluation

Let us list once again the key features of the Viessmann Vitodens 100-W WB1C110 that are worth noting: excellent efficiency of 108.4%, electronic control, thermometer, pressure gauge, connected underfloor heating, there is a circulation pump. The boiler is mounted on the wall, and the protection systems include, as described above: overheating protection, freezing protection, gas control and a safety valve. The heat exchanger is made of stainless steel, the combustion chamber is closed.

Design options

There are different designs of Viessmann Vitopend 100-W boilers:

• Single-circuit. They are designated by the letters A1HB (for example A1HB001). They only heat the coolant for the heating circuit.
• Dual-circuit. These settings are designated A1JB (eg A1JB010, A1JB009). In parallel with heating the coolant, hot water is prepared for domestic needs.

All single-circuit boilers have the ability to connect an external boiler, which allows not only to heat the coolant, but also to supply hot water. At the same time, the volumes of hot water are much greater than what a standard plate heat exchanger of a double-circuit boiler can provide.

This is convenient if the room size is relatively small and the need for hot water is large.

Types

There are different types of Viessmann floor-standing boilers, which differ in design and method of transferring thermal energy.

Offered:

• Convection boilers . Their work uses a traditional heat exchange method, the efficiency of which has been brought to a high limit.
• Condensing boilers . They are equipped with an additional unit - a condensation chamber, in which water vapor is deposited from the flue gases. In this case, a significant amount of thermal energy is released, which is transferred to the coolant. Preliminary preparation allows you to reduce the heating temperature in the heat exchanger, which automatically reduces gas consumption.

Almost all models of floor-standing boilers are single-circuit, except for the only Vitodens 222-F line, equipped with a built-in boiler.

The absence of a DHW module does not mean that it is impossible to supply the premises with hot water. All models have pipes for connecting an indirect heating boiler, in which a hot coolant circulates through a copper coil, heating the water.

Models of floor-standing boilers have different capacities, usually quite large, designed for operation in larger areas.

Technical characteristics of Viessmann Vitopend 100-W boilers

Gas equipment has the following parameters that distinguish it from analogues:

• Stainless steel is the main construction material. The body and burner are made precisely on this basis. In wall-mounted devices, the heat exchanger is also made of steel, which helps to increase the service life for those who have a Vitopend 100 W gas boiler.
• Use of a large number of additional sensors. They help control the operation of the device remotely. This is a simple, convenient option.
• The design includes a special modulating burner. These are special designs that save up to 92% of gas. The effect is especially noticeable in the summer, when the device itself is not used.

For hot water, the boiler productivity will be from 10 to 14 liters per minute. It all depends on which model is chosen in a particular case. From a 220-volt power supply, energy consumption will be up to 120 W. Experts advise purchasing an additional voltage stabilizer for the Visman Vitopend 100 gas boiler to avoid additional breakdowns.

Note! With low fuel consumption, the equipment runs on natural and liquefied gas.

Device

The design of wall-mounted boilers Viessmann Vitopend 100-W is in no way inferior to the most advanced modern developments of the most advanced manufacturers.

Main components of the boiler:

• Atmospheric type gas burner.
• Heat exchanger.
• Diaphragm expansion tank.
• Fan for removing combustion products.
• Hydraulic group consisting of a three-way valve, a secondary heat exchanger, a circulation pump and connecting pipelines.
• Electronic control board, sensor system, external panel with display.

The coolant enters the boiler from the heating circuit. As it passes through the heat exchanger, it heats up, after which it immediately goes to the secondary plate heat exchanger, where it transfers part of the thermal energy to heat hot domestic water.

Then, in a three-way valve, it acquires the temperature specified by the program, for which the hot and cooled return flows are mixed. After this, the liquid again enters the heating circuit.

The operation of all elements is constantly monitored by a system of sensors connected to the control board.

How the device works

The operating principle of the gas boiler pressure switch is as follows. The sensor is equipped with a pair of contacts that are connected to two control circuits. In operating mode, one pair of contacts is closed; in standby mode, the other is closed.

Electrical resistance depends on gas pressure, and as pressure increases, resistance decreases. Since an increase in pressure characterizes either a violation of draft or overheating of the coolant, this parameter determines the possibility of normal operation of the boiler and, therefore, the need for its immediate shutdown. In the work of this type of indicator, two stages are clearly distinguished.

1. Ignition of gas. The heating system microprocessor supplies operating voltage to the air supply fan to the combustion zone. At the same time, the flame control function is turned on and the boiler goes into operating mode.
2. After the fan starts, the temperature drops, which triggers another pair of control contacts. If for some reason this does not happen, then when you try to re-ignite, only the fan will turn on, and the flame control function will not be activated. Thus, the boiler will not turn on. The launch will only take place when the air pressure is within the required limits.

Unlocking the emergency state of the boiler

1. Use the heating temperature control knob on the boiler instrument panel to set the temperature to maximum.
2. Then sharply turn off the temperature regulator to zero.
3. We repeat the procedure 2-3 times, turning the sensor either to maximum or to minimum.
4. We leave the regulator in the maximum temperature position and wait for the boiler to automatically unlock. The system should start automatically.
5. We wait until the emergency stop light of the device goes out.
6. After such manipulations, set the regulator to the desired temperature.

Characteristics

Among the gas double-circuit boilers of this manufacturer, two main types can be distinguished: chimney boilers and turbocharged boilers. A special feature of chimney systems is that they can only be installed in rooms that have adequate ventilation and chimney removal. The second model is characterized by the possibility of installation in almost any room and even in an apartment, since such devices do not require special ventilation, and combustion products are removed thanks to a fan.

The standard model is a chimney, and it is purchased much more often. This version of the heating system has the boiler itself, a mounting frame and corresponding pipes for installing the ventilation system.

In general, the Viessmann chimney boiler has the following technical characteristics:

• The power parameters of the heating device can be set independently depending on individual preferences. On average, the minimum rating for boilers of this type is 10 kW, and the maximum is 23 kW.
• The boiler has an expansion tank with a capacity of 6 liters.
• Temperature indicators are also set independently. Typically, the maximum water heating value is 85 degrees, and the minimum is about 30 degrees.
• The dimensions of the boiler are 40x72.5x34 cm, and the weight is about 35 kg.

The boiler has a control panel with an electronic indicator of the set values. This will not be particularly difficult, since all the controls are marked and understandable. A convenient display can show the temperature of the water in the system, the level of gas combustion, and if a malfunction occurs, it issues a special code, the designation of which can be found in the accompanying operating rules. There is also a pressure gauge on the panel (round scale with an arrow).

It is intended to indicate the pressure level in the heating circuit. After installing the entire system and starting to fill it with water, you must carefully monitor the pressure gauge readings. The manufacturer Viessmann indicates that the pressure should not exceed 1.5 bar. Also on the panel there is a button to turn the heater on and off.

Room thermostats are sold separately, on which the required temperature value is simply set, and the thermostat itself controls the heating device. Some thermostats have set temperature values ​​that should change throughout the day. For example, during the day the boiler may heat less, but at night more. There are also devices that allow you to control the boiler remotely.

Series models

The Viessmann Vitopend 100-W series has two model lines:

• Single-circuit boilers are designated by numbers from 001 to 004.
• Double-circuit boilers are designated by numbers 009-012.

Numbers 001, 002, etc. indicate the boiler power.

Each model is marked with its own digital code:

• Number 001 is assigned to a single-circuit boiler with a capacity of 24 kW.
• 002 - single-circuit boiler, power 29.9 kW.
• 003 - power 34 kW.

Double-circuit boilers start with number 009:

• 009 - 12 kW.
• 010 - 24 kW.
• 011 - 29.9 kW.
• 012 - 34 kW.

Codes 004 to 008 are assigned to ready-made solutions, sets of single- or double-circuit boilers and external water heaters.

Digital marking is convenient in that it allows you to shorten long symbols to three digits, which accurately indicate a specific boiler model. This is convenient for both technical personnel and retail chain workers, speeds up model identification and simplifies document flow.
