Air-to-water heat pump: our installations

Every installation is different. Discover our air-to-water heat pump projects completed by Hecker & Frères Énergie (HFE) in Lille and the metropolitan area — from oil or 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.

    Efficient heating and DHW for a family of five, with excellent output even in cold weather.

  • Greener

    Natural R290 refrigerant, oil phased out and a concrete energy transition for the home.

  • High temperature

    Compatible with existing radiators thanks to high-temperature water production.

  • Durable install

    Ø42 electro-galvanised steel network, full pipe insulation and careful commissioning in 4 days.

About this installation

A new Hecker Frères Énergie project: our teams replaced an old oil boiler with a latest-generation Panasonic Aquarea T-CAP Monobloc R290 25 kW heat pump. This high-performance unit uses natural R290 refrigerant and delivers excellent efficiency even in very cold weather, while supplying existing radiators thanks to its high-temperature water output.

To meet the needs of a family of five, we also installed an Atlantic 250-litre thermodynamic water heater for domestic hot water — an excellent balance of comfort, energy savings and environmental performance.

The renovation was completed by two technicians in four days, with careful detailing and full compliance with current standards. The owners now enjoy a heating and DHW system that is more economical, greener, quieter and perfectly suited to their home.

Work carried out

  • Full removal of the old oil boiler.
  • Installation of a Panasonic Aquarea T-CAP Monobloc R290 25 kW heat pump.
  • Fitting of an Atlantic 250 L thermodynamic water heater.
  • Complete hydraulic network in Ø42 electro-galvanised steel for durability.
  • Thermal insulation on all pipework to limit heat loss and improve overall efficiency.
  • Sanitary expansion vessel on the thermodynamic cylinder to protect against pressure variations.
  • Hydraulic commissioning, start-up and performance optimisation.

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.

    Gentle, even warmth throughout the home.

  • Lower bills

    Electric direct heating replaced with an efficient system.

  • Softened water

    Water softener installed to protect the circuit.

  • Added value

    A full central heating network increases property value.

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.
