aquaTherm
Domestic Heat Pump Water Heater
PHNIX aquaTherm is a water source heat pump water heater designed for homes that already have a hydronic heating system. Working alongside an air-to-water heat pump, geothermal system or boiler, it uses available heat from the water circuit to produce efficient domestic hot water. This integrated approach makes better use of the home’s existing energy system, offering a practical solution for both new-build and renovation projects.
