Installation of a heat pump
We size, install and commission your heat pump from A to Z. Thermal assessment, choice of technology, hydraulic and electrical connection, control: an installation designed for real efficiency and a clear quote with grants estimated.
A complete installation, from assessment to commissioning
A high-performance heat pump is not just about the equipment: it is the right sizing and careful connections that make the difference on your bill for fifteen years.
Thermal assessment & sizing
Calculation of your home’s heat losses to choose the right power. An oversized heat pump wears out in short cycles; an undersized one struggles in severe cold.
Choice of technology
Air-to-water, air-to-air or geothermal: we compare according to your home, your emitters and your budget, aiming for the best real COP.
Hydraulic connection
Connection to the existing heating circuit — radiators or underfloor heating — with a decoupling tank and balancing if needed.
Domestic hot water tank
Installation and connection of a hot water tank sized for your household, with safety devices and back-up, for reliable hot water all year round.
Electrical connection
Dedicated supply, protections and bringing the panel up to standard. We check compatibility with your installation and any dual-rate tariff.
Commissioning & control
Setting up the heating curve, the setpoints and the time slots, then checking operation. A well-tuned control means immediate savings.
From study to commissioning
-
Study & thermal assessment
Technical visit, survey of heat losses and emitters, choice of the technology and power suited to your home.
-
Quote & grants estimated
A clear quote, with the regional grant estimated and where to claim it, and VAT 6% applied in renovation. No nasty surprises.
-
Installation
Fitting of the units, hydraulic and electrical connection, domestic hot water tank. A clean and scheduled job.
-
Commissioning
Setting up the control, operating tests, handover and delivery of the file for the grant and the warranty.
Why replace a fossil boiler
Where a gas or oil boiler burns energy, a heat pump returns three to four times more than it consumes. Replacing fossil heating is also the condition for securing the regional grant.
- COP 3.6 to 3.8: one kWh consumed for 3 to 4 kWh of heat
- Replacing a fossil boiler = condition for being granted the subsidy
- No more fossil energy, emissions cut and a stabilised bill
We come to carry out the thermal assessment at your home and hand you a clear quote, grants estimated, with no commitment.
Heat pump installation
How much does installing a heat pump cost?
Expect roughly €8,000 to €15,000 installed for an air-to-water heat pump, €4,500 to €8,000 for an air-to-air one and €15,000 to €25,000 for geothermal. These amounts are before grant: in Wallonia, the grant reaches €4,000 for an air-to-water unit, and up to €4,500 in Brussels. Our quote estimates your remaining cost once the grant is paid out.
Which heat pump technology should I choose?
Air-to-water replaces a boiler and feeds radiators and underfloor heating: it is the most common choice in renovation. Air-to-air heats by blowing air and can cool in summer. Geothermal offers the best efficiency but requires drilling and a higher budget. The thermal assessment decides according to your home.
How do I obtain the regional grant?
The grant is conditional in particular on replacing fossil heating and on using a qualified installer. The application is submitted to your region — we explain how, and we provide the detailed quote, certificates and technical sheets so that you know your remaining cost from the start.
Do you benefit from VAT at 6%?
Yes, for a home over ten years old, the reduced VAT of 6% applies to the labour and the supplies of the installation. It is an immediate relief applied to the quote, on top of the regional grant.
How much does an installation cost?
| Service | Range | Typical lead time |
|---|---|---|
| Air-to-water heat pump (radiators / underfloor) | 8,000 – 15,000 € | On study |
| Air-to-air heat pump (multi-split) | 4,500 – 8,000 € | On study |
| Geothermal heat pump (drilling included) | 15,000 – 25,000 € | On study |
| Domestic hot water tank | on quote | With the installation |
| Thermal assessment & sizing | included in the quote | Before the job |
