Local heating sites represent the most important source of air pollution in the South Moravian Region. These are mainly technologically obsolete and non-ecological boilers belonging to the 1st or 2nd emission class according to ČSN EN 303-5, which allow to heat uncertified fuels or household waste without any possibility of controlling the combustion process. The aim of the project is to improve the quality of the environment, human life and health in the region through the exchange of these non-ecological boilers to solid fuels.
