Heat Pumps

Pool heat pumps require electricity to operate and are known as ‘air to water’ heat pumps. They extract heat from the ambient air around them and transfer the heat to your swimming pool water. They are not dependant on direct sunlight like solar heating systems and are extremely energy efficient.

How a Swimming Pool Heat Pump Works:

Water is drawn from your swimming pool via the filtration system into the pool heat pump. A large fan on the heat pump draws ambient air surrounding the heat pump across the outer evaporator air coil.

Liquid refrigerant at low temperature within the evaporator coil absorbs the heat from the outside air and becomes a gas. The warm gas in the coil is then drawn into the compressor, which compresses the gas increasing the temperature. This hot gas then passes through the condenser. The condenser transfers the heat from the hot gas to the swimming pool water circulating through the heater. The heated water is then returned to the swimming pool. The hot gas then reverts to liquid form as it flows through the condenser coil then back to the evaporator, where the whole cycle starts again.
