Heat Pump Water Heating Systems
Heat pump water heaters are three times more energy efficient than conventional electric resistance water heaters.
Heat pumps work like a refrigerator in reverse. While a refrigerator pulls heat from inside a box and dumps it into the surrounding room, a stand-alone air-source heat pump water heater pulls heat energy from the surrounding air and uses it to heat the water in your geyser.

Heat pumps can be retrofitted to work with an existing conventional storage water heater (geyser).
The heat pump has a circulation pump that circulates water from the storage unit (geyser) through the heat pump. The heat pump has a fan that draws in the outside air and directs it over the evaporator coil. Liquid refrigerant within the evaporator coil absorbs the heat from the outside air and becomes a gas. The warm gas in the coil then passes through the compressor. The compressor increases the heat, creating a very hot gas that then passes through the condenser. The condenser transfers the heat from the hot gas to the cooler water circulating through the heat pump. The heated water then returns to the geyser. The hot gas, as it flows through the condenser coil, returns to liquid form and back to the evaporator, where the whole process begins again.
