An air source heat pump unit extracts heat from the air at low temperatures, which is then absorbed into a fluid, compressed to increase the temperature, and used to heat homes and provide hot water.
Air to Air system produces warm air to heat the home
Air to Water system distributes heat via the wet central heating system.
