How do ASHP's work?

Air Source Heat Pump’s convert heat from the air outside and transfers it to the hot tub water.

Our heat pumps draw air into the unit through an evaporator coil of liquid refrigerant, the air drawn in warms the coolant, which is pumped through to a compressor, the compression process then heats the refrigerant much more, the liquid moves through to a condenser and to a heat exchanger.

The heat exchanger is where the heated refrigerant passes off its heat into the hot tub water which then circulates back to the hot tub, the refrigerant now moves on to cool down through to the expansion valve and evaporator and begins its cycle again.
