Explore the full portfolio of Air-to-Water Heat Pumps offered by Withair®.

Withair® Air-to-Water Heat Pumps is according to the Reverse Carnot Cycle principle, drive by a little bit of electricity, the low temperature and low-pressure refrigerant absorb a large amount of heat from air, and be vaporized, then be compressed to high temperature and high-pressure gas by compressor, enter into the water heating exchanger transferring heat into water to make hot water, then throttled by electric expansion valve and continue new cycle, a steady stream of making hot water.

The heat generated by Withair® Air-to-Water Heat Pump is several times that of electric energy consumption. Compared with traditional electric water heater, gas water heater, the operation cost can be saved by 60% ~ 70%, and the investment cost is easy to recover. The heat pump water heater is a new type of water heater product with high efficiency, energy saving, environmental protection, safety.

No matter your application, there’s a Withair® Air-toWater Heat Pumps that’s right for you !
