A pool heat pump is a device to heat swimming pool water by transferring heat from the surrounding air to the water. It works similarly to a household air conditioner but in reverse. Instead of removing heat from indoor air, the pool heat pump extracts heat from the outside air and transfers it to the pool water, thus raising its temperature.
Energy Efficient Pool Heat Pumps
Pool heat pumps are more energy-efficient than traditional electric or gas pool heaters as they use electricity only to power the compressor and fan, while most of the heat comes from the air. They can operate at a lower cost and for a more extended period, even when the outside air temperature drops to around 10-15°C.
Wide Selection of Pool Heat Pumps
Pool heat pumps come in various sizes and models, suitable for different pool sizes and climates, and they can be installed in-ground or above-ground pools. They are eco-friendly, quiet, and can provide a comfortable swimming environment for a more extended swimming season, which is essential for those in colder regions.
A pool heat pump extracts heat from the surrounding air and transfers it to the pool water. It consists of an evaporator, a compressor, a condenser, and a refrigerant.
The process starts when the heat pump pulls in warm air from the atmosphere using a fan and passes it over the evaporator coil filled with a low boiling point refrigerant, which absorbs the heat from the air.
The warm refrigerant is then compressed by the compressor, which raises its temperature and pressure in the pump.
The high-temperature refrigerant is then circulated through the condenser coil, which is in contact with the pool water, and releases its heat to the pool water.
The now-cooled refrigerant goes through an expansion valve that reduces its pressure and temperature and returns to the evaporator, where the process starts again.
By repeating this cycle, the pool heat pump can continuously extract heat from the surrounding air and transfer it to the pool water, raising its temperature. This energy-efficient way to heat a pool requires minimal electricity compared to traditional electric or gas pool heaters.
