To make this measure more effective and tailored to the specific context of your company, we recommend that you first perform an overall analysis of your energy situation.
Installation of heat recovery extractor hoods
The project involves fitting professional kitchen extractor hoods with heat recovery systems on the exhaust air fan. This recovery can be performed in three different ways:
- via an air-to-air recuperator integrated into the hood which propels the preheated air into the kitchen (integrated compensation).
- via a separate air-to-air recuperator which also allows the make-up air to be preheated through a plate heat exchanger.
- via an air/water heat recovery unit to pre-heat domestic hot water
The company will be able to save an estimated 70-100% on heating consumption in the kitchen, and around 50% on domestic hot water production, by installing this technology, which has been on the market for over 5 years. However, implementing this measure can be complex with a medium-to-long-term return on investment, and requires the temporary shutdown of production during the technical installation stage.
Energy and environmental impact
Energy savings are achieved at the level of:
- kitchen heating that normally needs to warm up the new make-up air to room temperature (1 and 2)
- domestic hot water production (3)
The environmental gain stems from the two energy savings because there is waste heat recovery (fuel and/or electricity savings).
State subsidy application
State subsidies
Please note: any application for government or non-government subsidies must comply with the “incentive effect”, subject to compliance with the subsidy conditions.
To ensure that the ‘incentive effect’ is respected, no binding commitment (signing a quotation; paying an advance) may be made BEFORE submitting the application file or receiving the agreement in principle from the State or the electricity and natural gas supplier following an application for subsidies.
Temporary environmental impact aid
Extended “SME Packages Sustainability” aid scheme, to give companies greater incentives to invest in measures that significantly improve their environmental impact. Investments under this climate protection measure amount to 70% for small enterprises, 60% for medium-sized enterprises and 50% for large enterprises, for projects costing more than €7,500, with a maximum subsidy of €100,000.

N.B. State subsidies cannot be combined for the same project
Subsidies from electricity and natural gas suppliers
Since 2015, natural gas and electricity suppliers are required to make energy savings for consumers under the obligation scheme. Since then, energy suppliers have been offering support and advice, as well as subsidy programmes for consumers to implement energy efficiency measures.
The following suppliers offer this service for companies:
N.B. Supplier subsidies can be combined with any state subsidies for the same project.
