Heat Pump Hot Water

How a Heat Pump Hot Water Works
A fan draws in air, containing heat energy, across the evaporator. The evaporator turns the liquid refrigerant into a gas. The compressor converts refrigerant into high temp / high pressure gas. The hot gas inside the condenser coil heats the water inside the tank. The refrigerant reverts back to a liquid after heating the water & continues back to the evaporator for the process to start again.
