Field help: (2021) Renewal of the heating system

Renewal of the following heating systems is eligible for tax incentives:

• solar collector systems
• biomass systems
• heat pumps
• gas condensing technology ("Renewable Ready")
• hybrid systems
• fuel cells
• mini combined heat and power (CHP) (combined heat and power plants)
• connection to a heating network

As a rule, the eligible expenses can be taken from the statement of the specialist company.

The tax reduction cannot be claimed if the expenses have already been taken into account as business expenses, income-related expenses (e.g. in the case of double household maintenance), special expenses or exceptional costs.
