Field help: Renewal of the heating system

Enter the costs for renewing your heating system.

The renewal of the following heating systems is tax-supported:

  • Solar collector systems
  • Biomass systems
  • Heat pumps
  • Fuel cells
  • Mini combined heat and power systems (mini CHP)
  • Connection to a heating network

As a rule, no tax reduction is possible for new gas heating systems. Special rules apply only to certain "Renewable Ready" systems whose installation began before 01.01.2023.
