A non-chimney boiler is a heating device that does not require a chimney and draft to operate. Air intake and exhaust gas outlet is carried out through a special device - a coaxial pipe.
Chimneyless gas boilers are an excellent solution when it is necessary to install a heating device in a small room. They will also help to get out of the situation when it is impossible to equip housing with a stationary chimney. Such a heating system has a special smoke exhaust design, the main advantage of which is its compactness and location. It is located directly above the apparatus.
Equipment device
Chimneyless boilers are designed to perform the same function as conventional ones. They are able to heat the room and prepare hot water, but their combustion chamber is arranged somewhat differently and there are differences in the principle of operation. If a conventional gas apparatus operates at the expense of a chimney and draft, then this model takes air and discharges exhaust gases through a coaxial pipe. Equipment of this type can be connected to the system from one or two sides. In this case, gases are removed through the inner part of the coaxial pipe, and air is taken into the boiler through the outer system.
The design of smokeless gas boilers is very convenient to use, and besides, it is fireproof. The high temperature of the combustion products is extinguished by the cold air coming from the street. Another plus is that the boiler is undemanding to the presence of draft and air flow - all these operations are performed forcibly due to the fan built into the equipment.
Types of boilers
Chimneyless boilers can be wall-mounted and floor-standing. The most effective are wall-mounted, single-circuit, smokeless gas boilers. This model performs its main function not only due to the combustion of gas, but also due to the use of the residual heat of the condensate obtained from the vapors of the air discharged into the atmosphere. Particularly good results can be achieved with low-temperature operation, in particular, if a certain section of the heating system is made according to the underfloor heating principle. Since the temperature of the coolant in the "warm floors" system is only 45-50 ° C, this makes it possible for water vapor to condense more strongly in the exhaust gases.
Condensing units have the highest efficiency, environmental friendliness and minimum fuel consumption. The disadvantage of such equipment is the need for a special drainage of condensate obtained during operation. Such moisture should not be discharged into surface water or soil, as it is saturated with acids and can disturb the bacterial microflora. For wall-mounted condensing boilers, the chimney must only be made of high-quality plastic that is resistant to acid fumes.
