The aim of the project is to improve air quality in SČK, namely to reduce emissions from heating in local furnaces mainly by solid fuels, which by their emissions represent a decisive source of pollution load (suspended PM 10, PM 2,5 , benzo(a)pyrene). The target will be met by replacing at least 1,350 stationary solid fuel combustion sources in households in the Central Bohemian Region. Ecodesign and at least energy class A+ heat pumps and biomass boilers will be supported.
