How does an air source heat pump work?

A heat pump works like an air conditioner, only in reverse. In essence, it takes air from the atmosphere, extracts the heat and transfers it to the water passing through the pump.

From a technical perspective, a heat pump pushes a refrigerant through its copper heat exchanger coils. Then, the compressor and condenser work together to change the refrigerant’s state from a cool liquid to a warm gas.

In heating mode, the liquid refrigerant boils as it travels through the coils. Any heat carried within the refrigerant is stored until it evaporates; then, the gas is compressed, which increases its temperature. Finally, the gas moves through a pressure valve, which returns it to a liquid state while transferring the heat to the element.
