What Is an Air-to-Water Heat Pump and Why Is It Perfect for Quebec Homes with Radiators?
An air-to-water heat pump extracts thermal energy from the outside air and transfers it to water, which is then circulated through your home’s existing hydronic system — such as radiators, baseboard heaters, or radiant floor tubing. Unlike air-source heat pumps that blow hot air, this technology delivers gentle, even, radiant heat that warms objects and people directly, creating a uniquely comfortable environment — similar to traditional boilers, but far more efficient.
In Quebec, many older homes and heritage buildings rely on water-based heating systems (radiators or in-floor loops) installed decades ago. Replacing them with a full ducted system is often costly and disruptive. An air-to-water heat pump offers a revolutionary alternative: it replaces your oil or gas boiler while keeping your beloved radiators or underfloor heating intact. With efficiencies up to 400% (COP > 4), it slashes fuel costs dramatically and eliminates the need for fossil fuels — reducing emissions while preserving your home’s character. Combined with advanced filtration and smart controls, it also improves indoor air quality and humidity levels year-round.
Choosing an air-to-water heat pump means choosing comfort that feels natural, efficiency that saves money, and sustainability that respects your home’s history. Let Thermopompe Montréal upgrade your hydronic system with the future of heating.
