Underfloor heating: our installations
Every installation is different. Discover a low-temperature underfloor heating project completed by Hecker & Frères Énergie (HFE) in Lille and the metropolitan area — paired with an air-to-water heat pump for optimal comfort.
Low-temperature underfloor heating installation
At Hecker & Frères Énergie (HFE), we install low-temperature underfloor heating systems for both new builds and renovation projects. Paired with a heat pump, underfloor heating is now one of the most comfortable, economical and efficient heating solutions on the market.
Unlike traditional radiators, underfloor heating delivers gentle, even warmth across the entire floor area of the home. Heat is distributed uniformly from floor to ceiling, eliminating cold spots and providing optimal comfort in every room.
Underfloor heating operates at low temperatures, typically between 25 and 35°C, making it perfectly suited to air-to-water heat pumps. This combination delivers excellent energy performance while significantly reducing heating consumption.
The advantages of underfloor heating
- Gentle, even warmth throughout the home.
- Superior thermal comfort compared with traditional radiators.
- Low-temperature operation, ideal for heat pumps.
- Reduced energy consumption.
- No loss of space thanks to the absence of radiators.
- Uniform temperature in every room.
- A discreet, invisible solution.
- Adds value to your property.

About this installation
As part of this project, we installed a low-temperature underfloor heating system designed to operate with an air-to-water heat pump.
This heating solution provides gentle, even heat distribution throughout the home, delivering excellent thermal comfort while limiting temperature fluctuations. Thanks to its low-temperature operation, underfloor heating optimises the heat pump's performance and helps reduce energy consumption.
The absence of radiators also frees up space in the rooms and improves the interior aesthetics of the home. This system is now one of the most comfortable and efficient heating solutions for new builds and renovations alike.
