Chimney systems designed to work in hypertension <200PA
Chimney systems designed to work in overpressure <200 Pa
Overpressure chimney systems are intended for heating devices with a closed combustion chamber. Closed combustion chambers are those in which the air needed for combustion is taken from the outside of the building, which is different than in the case of vacuum chimney systems.
Closed combustion appliances are generally safer than other types of appliances. Condensing boilers are currently produced on the market. They recover heat from the exhaust gases, which makes the heating device more efficient, and at the same time allows you to save a lot on the amount of fuel used to fire the heating device. The exhaust is ejected as a result of the use of a special fan that releases the exhaust fumes outside the building.
Regardless of the choice of the heating device, one should also remember about the appropriate system of chimney inserts. An important aspect is the selection of the system in terms of the type of fuel used to fire the boiler. A suitable system is a guarantee of failure-free operation of the stove and the correct chimney draft.
The most popular fuel used to fire heating devices is gas or heating oil. Specially dedicated chimney inserts for this type of fuel are also intended for condensing boilers. This is undoubtedly the KK - Single-wall SPS system for condensing and overpressure boilers.
You can also choose insulated chimney systems, such as KKD - insulated KK system or KPD - insulated KP system.
For users interested in connecting several boilers to one flue gas duct, the KP - coaxial air-flue gas duct is designed.
