Boiler equipment for the heating function is considered to be the most productive and effective. In contrast to the classical home heaters, these units are mostly unable to form the main heating system, not just auxiliary. But there is a flip side of such equipment. It is more expensive and requires a lot of energy. From the point of view of economic expediency, the optimal solution would be a gas boiler with a closed combustion chamber, which also has a high degree of safety. It is a modern variation on a traditional flue system, but with a number of structural modifications and improvements.

The equipment

The General structure of the Assembly is generally similar to models for working with open fires. In the simplest modification of the single-circuit gas boiler with closed combustion chamber is composed of three components. It directly the camera and its infrastructure, two of the expansion tank and a holding tank. It should be added and pipeline infrastructure, which provides the link between these elements and at the same time can act as a conductor of heat around the house.

The Foundation of a boiler unit is the burner that works not from the oxygen in the room and air supply from the outside. This explains the high reliability of this equipment. Depending on requirements, can be an effective double-circuit gas boiler with closed combustion chamber, is further provided with a node for providing hot water. Such models are more expensive and problematic to install, but performance and functionality. To ensure a similar problem of hot water due to the single-boiler will need to install an additional boiler will be more expensive.

Working Principle

gas boiler wall-mounted single-loop

Most of these boilers are used to maintain two systems. First and foremost is the heating function that is performed and one-and two-loop system. The second option can also work on providing domestic hot water. In both cases, the basis of the boiler acts as a flare gas burner. It works from the main pipeline or tank filled with liquefied fuel. Modern gas boiler with closed combustion chamber solenoid valve element that automatically stabilize the function of the unit. Since the gas equipment is considered the most dangerous from the standpoint of everyday usability, the developers of the models with a sealed burner seek to minimize risk in all aspects, and the presence of valves is one of the main protective devices. After the burner finishes the task of heating water is sent to the circuits in the respective tanks or distributed for circulation around the house.

Flue gas

In the boilers with traditional combustion system and natural smoke extraction provides for removal of their gas-burning device through the inner surface of the heat exchanger. This feature to some extent regulates the stabilizer associated with the channel of the chimney. In the latest version machines this mechanism has been improved. So, even budget gas single-circuit wall-mounted boiler can be fitted with a powerful fan exhaust fan with the pressure sensor. Protective gear can stop the flow of fuel to the burner, if there were violations of ventilation function.

Automation

Automatic system implemented to provide the functions of two types – control and security. In the first case, sensors and controllers set optimal from the point of view of user programs, system parameters. In particular, they establish the desired mode of ignition, control capacity of the burner, adjust the volume of water in the circulation, etc. as for security system, gas boiler with closed combustion chamber in this part mostly protected from dangerous situations that can arise in the process of operation. For example, special sensors can turn off the burner if the flame is lost. Even the detection of abnormalities in the control system torch protective sensor may disable the operation of the boiler. The same applies to cases of insufficient coolant flow, disorders in smoke, overheating of the unit, etc.

Varieties

Already dealt with the differences between single - and dual-circuit models, but the equipment varies according to the type of placement method. In particular, a popular floor and wall units. If you intend to purchase powerful and efficient assistant for service hot water and heat a large house, it is better to choose a floor gas boiler with a closed combustion chamber with a volume tank. Installation on a solid floor or other Foundation-based involves the physical stability of operation of the device – so makes no sense to save at the working potential of the technology.

Wall-mounted model is advantageous in that, saveplace, although in terms of installation, some versions can also create problems. It all depends on model and materials for local finish. In addition, wall mounted gas boiler with closed combustion chamber rarely has high power – most often it is single-loop model. Therefore, this option would be best in the heating infrastructure of a small private home or a single room.

The manual

single-circuit gas boiler with closed combustion chamber

For starters, it should be noted that the boiler should be located only in rooms designed for this kind of equipment. It doesn't have to be a technical room – the unit can be installed in bathroom, kitchen, utility room or garage. Importantly, the conditions in this place are not contrary to the rules of fire safety. To use a gas boiler with a closed combustion chamber is possible when all connected heating circuits and water supply. The user interacts with the equipment is realized through the special relay and control panels. Typically, these parts are supplied with ergonomic controls sensors and indicators the operating parameters of the boiler. For example, indicating the volume of coolant, temperature, mode of operation of the burner, etc.

Manufacturers and prices

In the domestic market are a lot of decent offers from Bosch, Baxi, Protherm, Vaillant, etc. For the most part this wall model characterized by modest dimensions and at the same time high performance. For example, modification Gaz 7000W from Bosch has a power capacity of 35 kW, which is enough to service buildings with total area of 350 m2. In terms of cost, of course, this equipment is not the most attractive. For example, a gas boiler with a closed combustion chamber, which price is 20-25 thousand rubles., the budget is considered. Solid versions of major brands estimated at 40-50 thousand But the production practice shows that these costs are justified in the long term.

Conclusion

gas boiler with closed combustion chamber price

The Use of the gas equipment gives several significant advantages. First, the consumption of gas if you have access to the Central supply line inexpensive cost – at least compared to electric equipment. Secondly, even a low power gas boiler wall-mounted single-circuit when the competent organization of contour diagrams can provide a warm home is medium in size. Again, if you correctly calculate the circulation, and obviate the need for additional point sources of heating. But for larger houses it is desirable appeal to the two-loop complexes with ample storage. This is a multifunctional equipment, which will solve several tasks in the maintenance of a private household.
