Method and system for using the waste-gas heat of domestic heating boilers

摘要

Method and system for using the waste-gas heat of a domestic heating boiler (11), in which, by transferring the high-temperature heat of the flue gases 12 to heating water 18 and the remaining sensible heat together with the heat of condensation to air 19, the entire chemically bound heat of the fuels is extracted at the level of their upper calorific values, the specific combustion values, from the combustion gases 12 via two media 18, 19, and converted into useful heat in full measure.
