ADVICE & KNOWLEDGE

Explore the mechanism of an Air-to-water heat pump's operation.

An air-to-water heat pump functions by absorbing the latent thermal energy present in the air, which serves as the primary heat source. Through a refrigeration cycle, the heat pump uses a compressor to increase the captured heat’s temperature and transfers it to a water-based system. This heated water can then be utilized for space heating, as well as domestic hot water production.
