Which heat pump for your Braine house?

The choice of the type of heat pump depends on the configuration of your home and the existing heat distribution system.

Air-water heat pump: replacing the boiler

The air-water heat pump extracts energy from the outside air and delivers it via the hot water circuit of the central heating. It is compatible with underfloor heating, low-temperature radiators, or fan-coils. It is a favorable replacement for the boiler in Braine homes equipped with an existing hydraulic circuit. Good envelope insulation is recommended before installation to optimize performance.

Air-air heat pump: warm and cool comfort in one unit

The air-air heat pump distributes heat and cold through indoor units similar to air conditioning. It is reversible and particularly suitable for homes without a hydraulic network or as a complement to existing heating. It is also the solution for rooms that overheat in summer in well-exposed Braine homes.

Geothermal heat pump: maximum performance

Geothermal energy extracts energy from the ground via buried sensors. The ground temperature being constant throughout the year, its efficiency is higher and more stable than air heat pumps. It requires available land for horizontal sensors or drilling for vertical probes: large Braine properties in Lillois often have the necessary space. This is the option for the most ambitious projects, often associated with solar panels for maximum autonomy.

The Avenir Rénovations method for installing a heat pump in Braine-l'Alleud

Proper sizing ensures comfort in the middle of winter and an optimal COP throughout the device's lifespan. It's the preliminary work that matters.

Heat pump and regulations in Braine-l'Alleud

The installation of a heat pump is subject to certain administrative and technical requirements that are useful to anticipate.

Declaration for the outdoor unit

The outdoor unit of an air-water or air-air heat pump is subject to neighborhood rules regarding noise and setback. In Braine-l'Alleud, four-sided houses with gardens generally offer locations that easily meet the minimum distances from property boundaries. In denser areas (terraced houses, neighborhoods close to the center), special attention must be paid to the noise level of the chosen unit. Avenir Rénovations selects models whose acoustic power level is compatible with the neighborhood and Walloon regulations.

Grants and financial incentives

The Walloon Region offers grants for the installation of a heat pump as part of energy renovation. The amount depends on the performance of the heat pump (seasonal COP SCOP), the type of housing, and the household income. These grants must be requested before the start of the work. Avenir Rénovations informs you about the conditions in effect at the time of your project and can integrate this process into the overall support.

What is the price of a heat pump in Braine-l'Alleud?

Indicative price ranges in Belgium, complete installation, VAT included.

Type of work	Price indication including VAT
Reversible air-air heat pump (120 m² house)	8,000 to 14,000 €
Air-water heat pump (150 m² house)	12,000 to 22,000 €
Geothermal heat pump with vertical probes	20,000 to 35,000 €

A precise quote is established after a free thermal study of the home. For an air-water heat pump installed in a 150 m² Braine house with existing hydraulic circuit, expect between 13,000 and 20,000 € before deducting Walloon grants.

Heat pump and existing building: compatibilities

Many homeowners in Braine are wondering about the compatibility of their existing home with a heat pump. The answer depends on several technical factors.

Existing insulation

An air-water heat pump is more efficient when the home is well insulated. In a non-insulated house, it will have to compensate for significant thermal losses and will be oversized or less efficient. For Braine houses from the seventies without insulation, it is often relevant to couple the heat pump project with a wall and roof insulation program to optimize the return on investment of both works.

Existing heat emitters

Radiators sized for a boiler operating at 70 or 80 degrees are not optimal for a heat pump that ideally operates at 35-45 degrees. In this case, there are two options: replace the radiators with low-temperature models or slightly oversize the heat pump to work with the existing emitters. Underfloor heating, if your house is equipped with it, is the ideal emitter for a heat pump.

Recent or well-renovated homes

In Braine homes renovated with recent insulation and high-performance frames, the air-water heat pump performs excellently even with the original radiators. Seasonal COPs easily reach 3 to 4 (for 1 kWh of electricity consumed, 3 to 4 kWh of heat produced), which directly impacts the energy bill.

Maintenance and longevity of a heat pump in Braine-l'Alleud

A properly maintained heat pump lasts fifteen to twenty years. Annual maintenance is mandatory for heat pumps containing more than 5 kg of CO2 equivalent in refrigerant: it consists of checking the state of the refrigeration circuit, operating pressures, filter condition, and regulation. This annual check is carried out by a certified technician and can be covered by a maintenance contract. Avenir Rénovations offers this follow-up for the installations we carry out.
