Heat pumps: the criteria for receiving the « heating boost » premium are changing

The « heating boost » bonus allows you to finance the replacement of a gas, coal or oil boiler with a more energy-efficient installation. Thus, you can use this financial aid for install including:

• one air/water type heat pump ;
• one water/water or glycol/water type heat pump ;
• one combined solar system (a system combining a solar panel and a storage tank).

Since 1^er September 2026, for the installation of a heat pump, the premium may only be granted if the chosen model has received an approval by the State. This approval shall be granted to heat pump models which have both:

• obtained a European certification, guaranteeing their quality;
• have been manufactured in EEE (for monobloc heat pumps, the final assembly of the refrigeration system must have taken place within EEE; and for split heat pumps, which consist of at least 2 separate units, the final assembly of at least one subassembly of the refrigeration system must have taken place within EEE).

The list of heat pump models currently approved has been established in an order of 2 July 2026.

Moreover, since the 1st^er September, with regard to After the installation of a combined solar system, the « heating boost » bonus is conditional on the complete decarbonization, after works, of the heating system and/or for the production of domestic hot water. In other words, the works carried out must not lead to the install or maintenance of a heating and/or domestic hot water production system incorporating at least one piece of equipment capable of using fossil fuels.
