Air To Water Heat Pump

Looking for a versatile heating solution that's both eco-friendly and efficient? Enter the world of air- to-water heat pumps! These cutting-edge systems harness heat from the outdoor air and transfer it to water, offering a sustainable heating solution for residential, commercial, and industrial settings alike.

Comprised of an outdoor unit featuring a compressor, condenser coil, and fan, paired with an indoor unit housing a heat exchanger and circulating pump, the air-to-water heat pump is the epitome of advanced heating technology. Refrigerant absorbs heat from the outdoor air, seamlessly transferring it to water circulating through the indoor unit's heat exchanger.

But that's just the beginning - this dynamic system can also reverse its refrigerant cycle to provide cooling during warmer seasons. By extracting heat from indoor spaces and transferring it outdoors, it ensures year-round comfort and efficiency.

Utilize the heated water for space heating via radiators or underfloor heating systems, or for a reliable domestic hot water supply. The possibilities are endless with an air-to-water heat pump!

Experience the future of heating with an air-to-water heat pump. Enjoy sustainable, efficient heating solutions for all your residential, commercial, and industrial needs.
