To heat a country house or cottage, perfect gas boiler. He is one of the popular teploagregat, which are used for space heating. An important advantage of this equipment is that it runs on gas. Currently this is the most economical fuel used for space heating. In addition, gas has a lower cost than other fuels. To avoid confusion in various heating equipment, it is necessary to study the structure of the gas boiler and its components. Only then can you make the correct choice of the heat source. The device of the gas boiler each species is approximately the same.

Components

The Main elements are as follows:

  • Gas burner is a rectangular structure, in which is located the nozzle. They serve for supplying gas into the combustion chamber and provide a uniform flame, and thus a uniform heating.
  • As the heat exchanger is the box with the radiators. Inside it are tubes with coolant generally is water. When burning gas generates heat, which is transferred to the liquid. Device Combi gas boiler is equipped with two heat exchangers - primary and secondary.
  • To provide pressure on the highway use the heating circulation pump. This technical element can be in all types of gas boilers.
  • If there is an intensive heating of the coolant, it is necessary to take him for a while. For this is the expansion tank.
  • The Important point is the tap of products of combustion. They must be removed from boilers using natural draft or internal fan.
  • In the system control system includes a control unit gas boiler, which is carried out using various sensors.

Gas valve

In wall and floor units provided these items. The valve of the gas boiler is designed to regulate the flow of gas to the burner. That is, opening and closing items at the right time.

Outdoor gas boiler

Set this teploagregat must, subject to the availability of funds for its purchase, as well as sufficient space.
the device is wall-hung gas boiler

The Room must meet all technical requirements. Device outdoor gas boiler is quite simple. The only difference from other types is the presence of two-circuit heat exchanger.

The advantages and disadvantages of outdoor boilers

Among the advantages of such structures are the following:

  • No need to make zasypku combustible material, as the boiler runs on gas;
  • Efficiency is quite high compared with the cost of fuel;
  • Thorough heating a large area.

The negative aspects include the following:

  • To install this type of gas boiler is necessary to collect the relevant documentation, which takes a lot of time;
  • Inability to install flush with the walling;
  • The need of furnishing a premises with special ventilation for removal of products of combustion.

Wall-mounted gas units

While Remaining compact, such an installation may perform the functions of a boiler. Device wall-mounted gas boiler is no different from the outdoor type, except for the dimensions.

Pros and cons of wall units

Among the advantages of this type of gas boiler are the following:

  • Compact size that allows it to be installed together with other appliances or furniture elements;
  • The package boiler includes all the necessary elements, installation of additional cumbersome equipment is not required;
  • If a long time there was no gas, the device can be easily reconfigured through the use of gas cylinders.

Like every unit, wall-mounted boiler has its drawbacks:

  • Gas boiler allows heating a large area of the room.
  • Having sensitivity to chemical properties of the coolant. If not installing the optional fabric softener, a heat exchanger will fail. And its replacement is quite expensive.
  • If the device heating the gas boiler provides the presence of a dual-circuit system, it is necessary to install additional tap. In the open position it serves to ensure that the coolant is cooled. The water flow starts 10 seconds after opening the valve.

device outdoor gas boiler

Unlike the wall from outdoor equipment

The Device is a gas boiler floor type different from wall-mounted products. This is reflected not only in the cost, installation conditions, and technical parameters. Them determine the type of boiler. In addition, outdoor models have a longer service life. This characterization depends on the material of construction of all structural elements. As a rule, the boilers are made of thick layer of cast iron, thankswhat they long time are not subject to corrosion.

The design of the unit provides several types of burners: atmospheric and ventilation. The first type is an inexpensive and easy to operate and does not cause much noise. The second type of burner is often found in hanging pots. They are more expensive but have more power.

Security System

Security System is an important issue when choosing of such equipment. When you turn off the electricity, modern gas-fired boilers stop and continue to work automatically when the power returns, the. In case of disconnection of gas supply automatically close only burners. After this the system startup is done manually because the automatic method does not exist.

The Device is a gas boiler AOGV involves the installation of frost protection and energy saving equipment. Thanks to the sensors to control the temperature of the coolant.

When it falls to 5 ºgas boiler switches on to heat. As you know, the heating in the summer is not required. So, that's not broken rotor, you must turn on the pump. For this boilers provided for a special function.

In modern devices establish a diagnostic system. They can independently perform analysis of all elements and give information about the overall state of the system. Such model checking up to 90% of all equipment. Thanks to this, the experts quickly perform the replacement or repair of a specific device.

Cost boiler

As mentioned earlier, the price of wall hung and floor standing boilers is different. Thus, the cost of wall-mounted models ranging from 28 000 to 150 000 rubles, and outdoor — from 30 000 to 40 000 rubles. Do not forget that the installation of outdoor unit, you should collect a package of necessary documents and to arrange a special room that will result in additional financial costs.

Design and operation of the gas boiler

To Start with, in the room there is a thermometer that measures the temperature of the air. If it crashes, then trackedby valve will be switched to "heating". Then starts the circulation pump and the water begins to move by the heating system.
the structure and operation of the gas boiler

Then opens the gas valve and the burner ignited. Heating the coolant comes at the expense of energy release during the combustion of fuel. For measuring pressure and temperature the design includes the thermostat and the pressure gauge. When the temperature reaches the required parameters, the pump automatically switches off. Over time, this heating process is repeated. At a constant pump operation happens round the clock heating of the coolant, which transfers its heat to the radiators.

Automation

A Huge role in the functioning of a gas boiler plays an integrated automation system. It controls the operation of the unit in all modes and comprises the following elements:

  • Sensors, control the flame height at the burner, and temperature;
  • The system on and off the boiler in the event of failures in the power grid;
  • Sensors regulating the gas pressure in the event of problems with gas supply;
  • Devices used for protection from freezing, it is important for the cold period of year, when it is necessary to dismantle the boiler;
  • Hardware to activate the circulating pump when unused for long periods of the system;
  • Self-diagnostic system and identify errors in the individual elements.

If you know the device is a gas boiler, then you can easily choose the right model, thus saving money when buying and service.

Reviews

The views of users of wall and floor standing boilers are divided. Because these structures have a number of differences. So the wall Assembly can not heat a big area of the room than the outdoor counterpart. So people choose gas-fired boilers, starting from this principle.

So, users of wall-mounted devices emit a number of advantages. So, in their opinion, these units are of small dimensions that allows installation along with other elements. The negative side is the sensitivity to coolant. If the water is of poor quality, the heat exchanger can quickly be broken. Its replacement is quite expensive.

Boilers its technical characteristics superior to wall-mounted styles and are used for heating a large area.

gas boiler AOGV

The Only negative, which was a favourite of many users is the installation process. For installation of equipment necessary to provide a separate room, because it is quite overall. You also need to gather certain documents which takes a lot of time. Another important point is the withdrawal of products of combustion. In the room where you will install the unit, should be provided with natural or mechanical ventilation.

Conclusion

The Gas boiler is an important element of the heating system. He carries a heating fluid, which further flows in the pipes and radiators. Work on this type of fuel, as gas, isthe best option for creating a comfortable environment in the room. So, we found the device a gas boiler. I hope that this information will help you select the right device.
