Bonus for a solar water heater

The City of Brussels gives its inhabitants (postal codes: 1000, 1020, 1120, 1130 Brussels) a bonus for a solar water heater.

It is possible to reduce the amount of the energy bill by reducing dependence on fossil fuels (fuel oil, gas) and by using alternative energy sources. Even with our climate, a solar water heater makes it possible to provide 60% of the energy required for the production of hot sanitary water in a home for free. In addition, there is a direct environmental benefit with such an installation through a reduction in atmospheric pollution and a reduction in greenhouse gas emissions.

The bonus is increased by 10% for works carried out by social economy companies, tailor-made companies or social integration companies.
