The project aims to promote the exchange of non-compliant heating sources to solid fuels in family houses to reduce pollutant emissions in the region. The eligible end-users of the funds will be natural persons/households of the Moravian-Silesian Region. The aim of the project is to replace at least 8654 boilers for solid fuels that do not meet classes 3, 4 or 5 according to ČSN 303-5 for new, more environmentally friendly heating sources until 2019.
