There is no universal heat pump: an apartment, an older terraced house and a new villa have neither the same constraints nor the same emitters. This guide helps you identify the technology suited to your home, then routes you to the page dedicated to your case for a grant-deducted quote.
The right choice depends first on three things: the space available for an outdoor unit, the insulation of the fabric and the emitters already in place (radiators or underfloor heating). Here are the main cases we come across in Belgium.
Little space outside and sometimes a co-ownership: we steer towards an air-to-air heat pump (split or multi-split) or a compact air-to-water unit. The installation is planned around façade and neighbour constraints. → "Heat pump in apartments" page.
A home over ten years old, often gas- or oil-heated with radiators: the air-to-water heat pump replaces the boiler and benefits from 6% VAT and the grant. The insulation and the emitters dictate the flow temperature. → "Heat pump in renovations" page.
Well-insulated fabric and underfloor heating: ideal ground for a low-temperature air-to-water unit with a high COP, or even geothermal on a villa or a farmhouse with land. This is where efficiency is highest. → "Heat pump in new builds" page.
Apartment, terraced, detached, villa or farmhouse: the space available for the outdoor unit and the neighbour constraints already rule out certain technologies.
A recent, insulated fabric allows a very efficient low-temperature air-to-water unit. An older home means looking first at the insulation and the emitters in place.
Underfloor heating favours low-temperature operation at the best COP. With old radiators, we check whether a high-temperature heat pump or add-ons are needed.
Theory points the way; the thermal assessment decides. We calculate the heat losses at your home and validate the technology and the output, with no obligation.
Even before comparing technologies, two factors determine the real efficiency: the quality of the insulation and the flow temperature your emitters demand. Underfloor heating in an insulated home gets the best out of an air-to-water unit; old radiators in a leaky fabric require a high-temperature heat pump or works first. It is this diagnosis, not the type of home alone, that guides the choice.
Describe your home to us: we steer you towards the right technology and the dedicated page, then come and run the thermal assessment.
In an apartment, space and co-ownership are the first constraints. We most often steer towards an air-to-air heat pump (split or multi-split), discreet and without major works, or towards a compact air-to-water unit if a heating circuit exists. The installation is validated with the co-ownership rules and the location of the outdoor unit. The dedicated "Heat pump in apartments" page details the solutions.
For a home over ten years old heated by gas or oil, the air-to-water heat pump is the most common solution: it replaces the boiler, reuses the radiators or underfloor heating and qualifies for the regional grant and 6% VAT. The key point is the flow temperature: depending on the insulation and the age of the radiators, we choose a standard or high-temperature heat pump. See "Heat pump in renovations".
A new home is well insulated and often fitted with underfloor heating: it is ideal ground for a low-temperature air-to-water unit with a high COP. On a large villa or a farmhouse with land, geothermal becomes relevant for even higher efficiency, despite a larger investment. See "Heat pump in new builds" and "Heat pump for large homes".
No. The type of home rules out certain options (space for the outdoor unit, co-ownership), but the final choice depends on the insulation and the emitters. Two identical detached houses can call for different heat pumps depending on whether they have underfloor heating or old radiators. That is why the thermal assessment remains the decisive step.
No: it is an orientation page. It helps you understand which family of heat pump suits your home and routes you to the page dedicated to your situation. The quote itself is drawn up after an on-site thermal assessment, with the grant deducted and the VAT applied.

« Châssis, panneaux et pompe à chaleur en une seule fois : on a eu un seul devis, un seul planning et zéro paperasse pour les primes. Le résultat est impeccable et notre facture d'énergie a chuté. On ne pensait pas que ce serait aussi simple. »
« Passage du mazout à une pompe à chaleur air-eau. Chantier propre, anciens radiateurs conservés. La maison est mieux chauffée pour bien moins cher. »
« PAC air-air réversible installée avant l'été. Confort été comme hiver, et le SAV répond vite. Très satisfait du suivi. »
