Why choose Avenir Renovations?
Our heat pump solutions in Brussels
There are several types of heat pumps, each suited to a particular housing configuration. Our specialized technicians guide you to the most relevant system according to your needs, budget, and building configuration.
Air/water heat pump
This is the most common solution in Brussels:
- it captures heat from the outside air to heat the water for your radiators or underfloor heating,
- it can also produce your domestic hot water (bi-block or monobloc model),
- compatible with low-temperature radiators or underfloor heating.
It is particularly suitable for renovations in Brussels homes with outdoor space for the outdoor unit.
Air/air heat pump (reversible air conditioning)
Ideal for apartments or homes without a water heating network:
- heats the indoor air in winter and cools it in summer,
- works room by room via wall units or consoles,
- quick installation and affordable price.
This type of heat pump is often chosen in Brussels buildings or for targeted renovations.
Geothermal heat pump (ground/water or water/water)
Rarely used in Brussels due to technical and administrative constraints:
- captures heat from the ground via buried probes or a borehole,
- very high efficiency but significant installation cost,
- requires suitable land and specific permits.
We advise you if you are considering this solution as part of a comprehensive renovation.
The 5 steps of a heat pump project with Avenir Rénovations
Avenir Rénovations installs your heat pump in Brussels in 5 steps: thermal study, solution choice, quote, complete installation, and assistance with procedures.
Why choose a heat pump in Brussels?
In Brussels, the heat pump reduces your bills, replaces fossil fuels, improves the energy performance certificate, and can evolve with solar panels or double flow ventilation.
A heat pump consumes 3 to 4 times less energy than an electric or gas boiler. It allows for a reduction in the annual heating bill.
The Brussels Region encourages the abandonment of fossil fuels. The heat pump is a clean alternative, valued in the energy performance certificate.
It can be combined with solar panels, a thermodynamic balloon, or a dual-flow ventilation system to optimize comfort and autonomy.
