An air-to-water HVAC system is a type of heat pump that extracts thermal energy from outdoor air and transfers it to a water-based system that delivers heating and cooling inside a building. This system replaces or supplements conventional heating and cooling equipment like boilers, furnaces, and air conditioners.
Unlike air-to-air systems (which blow warm or cool air into living spaces), air-to-water heat pumps transfer heat into a hydronic distribution system—which includes underfloor heating, fan coil units, or radiators. They can also provide domestic hot water, making them a complete HVAC solution.
In short, an air-to-water HVAC system is a clean, energy-efficient, and versatile way to heat and cool your space while also meeting hot water needs.
