The project will contribute to reducing emissions and improving air in the Pardubice Region by exchanging existing boilers to solid fuels in family houses with new heat sources. In the project we plan to replace at least 1180 pieces of boilers and the implementation of microenergy measures that will contribute to reducing the energy performance of buildings. As part of the calls announced, the staff of the boiler subsidy section will receive applications for subsidies from final applicants and pay subsidies after successful implementation of partial projects.
