The German Federal Office for Economic Affairs and Export Control (BAFA) has launched a subsidy programme for heating optimisation. The aim of the subsidy programme is to motivate homeowners to renew their heating systems with attractive, non-repayable subsidies to avoid an excessive energy consumption. Among other things, this is intended to make an important contribution to the environmentally friendly supply of heat in Germany. As of January 2021, the grant for individual measures in the Federal Support for Efficient Buildings (BEG EM) was introduced.
