Almost €43 million paid to residents who replaced inefficient boilers

Almost €43 million in grants have been paid out so far to people who have replaced polluting and inefficient heating equipment in their homes. In total, more than €49 million of public support has been granted to more than 14 800 residents.

The seventh call for proposals has been launched on 2 January 2026. An additional €3.3 million in grants is foreseen for this round. The calls for proposals are planned to be published every quarter of the year.

Nearly 13,000 inhabitants have already installed renewable heat generation units. Almost €43 million in support has been paid out to them.

The support is granted to residents who have installed new, unused Class 5 certified biofuel boilers or heat pumps (ground–water–water–water–water– air–water–and air–air) to heat their homes. The application must be accompanied by a payment application and documents certifying the installation of the heating installation. Applications must be submitted using an electronic form.

An average reimbursement of around €3,500 can be made when replacing an inefficient boiler with a heat pump and around €1,500 when installing a Class 5 biofuel boiler. The amount of the grant is calculated using fixed rates and taking into account the capacity of the installation.

According to the approved funding conditions, the grant is available to residents who have installed a new heat production unit in a one- or two-apartment dwelling house or a garden house heated by a water-based system no earlier than 26 July 2023. Also eligible are residents who, not earlier than 16 December 2024, have upgraded their heat generation equipment if an air source heat pump has been installed, or if the heating installation has been replaced in an apartment in a block of flats or other building previously heated by a wood-burning stove or fireplace.

One application per household per dwelling is allowed. There is no limit to the total number of applications if the heating installations are replaced in different dwellings.

More than €112.4 million of public funding is foreseen for the replacement of inefficient heating installations until 2029. The plan is to replace 20 504 inefficient and polluting heating installations and to create 166.3 MW of additional renewable energy generation capacity.
