Establishes a market incentive program for individual homeowners, businesses, and municipalities, allocating subsidies for the use of renewable energy. Funding is provided for private consumers who decide to have their heating system retrofitted to run on renewables. Funding is provided for the installation of solar thermal installations (with a collector area of up to 40 square meters), biomass-based heating systems (with a nominal heating capacity of up to 100 kW), and heat pumps (with a nominal heating capacity of up to 100 kW). The funding program places a special focus on setting up new installations in existing buildings. In the case of new buildings, funding is only available for certain innovative types of installations. Market Incentives Program
