The technical side

What you should know

What's the difference between an air-to-water and an air-to-air heat pump?

Air-to-water heats your water circuit (radiators, underfloor heating, hot water) and replaces a boiler; air-to-air blows warm air directly into rooms, like a reversible air conditioner.

Does a heat pump still work in very cold weather?

Current models stay efficient down to -15°C to -20°C depending on the technology; an electric backup kicks in automatically during exceptional cold snaps.

Do you need to replace your radiators to install a heat pump?

Not necessarily: an air-to-water heat pump can often work with existing radiators if sizing and flow temperature are suitable — that's exactly what we check during the assessment.
