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.

Waste heat recovery in oven exhaust system (baking ovens)

The project consists in installing a heat exchanger to capture the waste heat from the oven to heat the bakery store and to produce domestic hot water.

Installing this technology, which has been available on the market for more than 5 years, will allow the company to save up to 20% on its electricity consumption as well as reduce its carbon footprint by up to 20%. This measure is rather complex to implement, would entail a medium-to-long term return on investment, and requires a production shutdown during installation.

A heat exchanger can be used to recover waste heat from the flue gases from a gas, oil or pellet burner and/or from the vapours from the furnace. In a conventional operating mode, these fumes rise to temperatures of about 300°C and are usually discharged, along with the heat energy they contain, into the atmosphere through the flue.

Energy and environmental impact

Waste heat from gases is used to reduce:

  • electricity or gas consumption for the generation of domestic hot water
  • energy consumption to heat the store.

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 of the aid is respected, no binding commitments may be made (acceptance of a quote; advance)

  • SME Packages – Sustainability
    • Flat-rate subsidy of €5.000 for small and medium-sized companies for projects to reduce their environmental impact, costing between €5.000 and €6.650 excluding VAT
    • For any questions:

N.B. While several state subsidies cannot be granted for the same project, they can be combined with assistance from energy suppliers.

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 amount of the premium is proportional to the annual energy saving (in MWh). The following suppliers offer this service for companies:

N.B.: Supplier subsidies can be combined with a state subsidy for the same project.
