Air-to-water heat pump: our installations
Every installation is different. Discover 3 air-to-water heat pump projects completed by Hecker & Frères Énergie (HFE) in Lille and the metropolitan area — from gas boiler replacement to full central heating creation.
Air-to-water heat pump installation
At Hecker & Frères Énergie (HFE), we install air-to-water heat pumps for gas, oil or coal boiler replacement, central heating creation and domestic hot water production. As RGE QualiPAC certified installers, we size every system based on your property, insulation and actual requirements.
An air-to-water heat pump captures heat from outdoor air and transfers it to the heating circuit water: radiators, underfloor heating or a thermodynamic water heater. With a COP of 3 to 4, it delivers 3 to 4 kWh of heat for every 1 kWh consumed — an efficient and economical way to heat your home.
Every project includes a thermal survey before quoting. We also support you with MaPrimeRénov' and CEE grant applications to reduce your out-of-pocket cost.
Benefits of air-to-water heat pumps
- Up to 70% savings on heating bills.
- Direct replacement for a gas or oil boiler.
- Heating and domestic hot water from a single system.
- Compatible with radiators and underfloor heating.
- Eligible for MaPrimeRénov' and CEE (support by HFE).
- Even thermal comfort all year round.
- 20 to 25 years lifespan with regular servicing.
- Increased property value and improved EPC rating.

About this installation
As part of this energy renovation, we replaced the old gas boiler with a Panasonic 12 kW air-to-water heat pump, providing more economical and efficient heating.
For domestic hot water, we also installed an Atlantic 250-litre thermodynamic water heater, significantly reducing hot water energy consumption.
To ensure reliable operation and long system life, a full power flush of the heating circuit was carried out. We also replaced and overhauled the heating manifold to optimise network distribution and ensure the entire system runs at peak performance.

About this installation
As part of this energy renovation, we installed a 5 kW air-to-water heat pump dedicated to heating. The old electric radiators were fully removed and replaced with a complete hydronic central heating network. We created and distributed a new heating circuit throughout the home, with multiple emitters sized for even heat distribution and optimal comfort in every room.
This project replaced an energy-hungry electric heating system with a more efficient, more economical solution offering superior daily thermal comfort.
To protect the equipment long-term and improve water quality, we also installed a water softener. It effectively limits limescale deposits in pipes, sanitary fittings and the heating circuit, helping extend equipment lifespan while maintaining performance.
