Why choose a heat pump in Wavre?

The heat pump has several advantages that make it the preferred solution for ambitious energy renovation projects.

Exceptional energy efficiency

Where a gas boiler produces one kilowatt-hour of heat for each kilowatt-hour of gas consumed, a heat pump produces two to four for the same kilowatt-hour of electricity. This coefficient of performance (COP) translates into a real reduction in the energy bill, the extent of which depends on the electricity rate and the insulation of the home. This is why the heat pump performs best when combined with good insulation and solar panels that cover part of its electricity consumption.

A device that heats and cools

Most air-water heat pumps can operate in cooling mode in summer. Coupled with suitable emitters (fan-coils or reversible underfloor heating), they provide comfort in both winter and summer in a single device. For Wavre homes without underfloor heating, air-air models ensure this reversibility with indoor units similar to those of air conditioning.

Eligibility for Walloon grants

The installation of a heat pump entitles you to grants in the Walloon Region, the amount of which depends on the type of equipment and the household income. The overall energy renovation can combine grants for insulation and grants for renewable heating equipment. We inform you about the available schemes during the diagnostic visit.

Our method for installing your heat pump in Wavre

The installation of a heat pump is a technical project that requires a serious preliminary study.

The types of heat pumps we install in Wavre

Each housing configuration calls for a different type of heat pump.

Air-water heat pump

Extracts energy from the outside air and delivers it via the heating circuit water
Compatible with underfloor heating, low-temperature radiators, or fan convectors
Operates down to outdoor temperatures of -15°C
Outdoor unit to be placed in the garden or facade depending on the configuration

The air-water heat pump is the most suitable solution to replace a boiler in a home with hot water distribution. It is compatible with existing emitters if they are low temperature.

Air-to-air heat pump

Extracts energy from the outside air and distributes it via indoor units
Reversible system: heats in winter, cools in summer
Installation without hydraulic network: ideal for homes without underfloor heating
Quick implementation and lower investment than air-water heat pumps

Geothermal heat pump

Extracts energy from the ground via buried sensors (horizontal or vertical)
Higher and more stable efficiency than air heat pumps due to the constant ground temperature
Requires available land or drilling depending on the technique
Higher investment but longer lifespan and superior performance

What is the price of a heat pump installation in Wavre?

The budget depends on the type of heat pump, the power, and additional work. Indicative ranges in Belgium, VAT included.

Type of work	Price indication including VAT
Reversible air-to-air heat pump (120 m² house)	8,000 to 14,000 €
Air-to-water heat pump (150 m² house)	12,000 to 22,000 €
Geothermal heat pump with ground sensors	18,000 to 30,000 €

A precise quote is established after a free thermal study of the property. For a well-insulated 150 m² house in Wavre, an air-to-water heat pump of 9 to 12 kW is generally sufficient. The return on investment is between eight and twelve years depending on the electricity rate and initial heating consumption.

Switch to heat pump in Wavre

A heat pump lasts twenty years or more. It should be perfectly suited to your home from the start. The free thermal study produces this serious calculation that underpins everything else: power, model, compatible emitters. Avenir Rénovations sizes and installs your heat pump in Wavre.

Heat pump in Wavre: compatibility with the existing distribution network

The most common challenge when replacing a boiler with a heat pump is compatibility with existing radiators. An air-water heat pump operates at lower temperatures than a conventional boiler (35 to 45°C compared to 70 to 80°C). If the current radiators are oversized (which is often the case in houses from the seventies and eighties in Wavre), they can work with the heat pump without being replaced. We calculate the necessary emission power before recommending the replacement or retention of existing emitters.

Underfloor heating and heat pump: the ideal combination

Hydraulic underfloor heating is the heat emitter most compatible with the heat pump. It operates at low temperatures (28 to 35°C), which precisely corresponds to the optimal operating range of a heat pump. If your home in Wavre already has underfloor heating, the heat pump is the ideal replacement solution for the existing boiler. If you are considering renovating your floors, the installation of underfloor heating combined with a heat pump can be planned in the same project.

Noise and placement of the outdoor unit in Wavre

The outdoor unit of an air heat pump produces operational noise that must be taken into account in its placement. In Wallonia, acoustic standards govern noise nuisances at property boundaries (40 to 45 dB(A) depending on the zones). Avenir Rénovations analyzes the placement of the outdoor unit to respect these limits concerning neighbors and reduce noise nuisances perceived from inside the home.

Solutions exist for difficult placements: vegetated or mineral acoustic screens, increased distance from windows and terraces, ultra-quiet models for constrained environments. These choices are integrated into the proposal before installation.
