The Water Source Swimming Pool Heat Pump from Walt Barrett

Swimming pool heat pump
Why choose a heat pump or Competition Swimming Pool Heat Pump?
Simply because it is inexpensive - to buy - to run - to install. Generally, the main heating systems available for swimming pools are Gas , Electric or Oil heaters. Some of these heaters can be beneficial from a cost point of view but tend to loose their appeal when it comes to installation costs. What the other heating systems cannot offer you is both the heat efficiency and low running cost!
How does a swimming pool heat pump work?
The swimming pool heat pumps are a super efficient way to heat the swimming pool. It makes full use of the advanced refrigeration technology to capture the heat in the outside air and transfer it to the pool water.
Environmental refrigerant gas absorbs and transfers the great heat energy through the refrigeration circulation system.
The swimming pool heat pump fan circulates air through the outer Evaporator Air Coil that acts as a heat collector. The liquid refrigerant in the air coil absorbs the available heat in the air transforming it to a gas. The refrigerant gas is then pumped by the Compressor. When this warmed gas is compressed, it intensifies or concentrates the heat. This intensely hot gas is then pumped into the Heat Exchanger Condenser where the actual heat exchange takes place.
As the swimming pool water passes through the Heat Exchanger, the hot gas gives up its heat to the cooler pool water. The refrigerant returns to a liquid state and is pumped through the Expansion Valve and then into the Evaporator Air Coil to start the process over again. A Water source Competition Water swimming pool heat pump does not generate heat, it simply captures it and moves it from air to water thus, providing an efficient and environmentally friendly system for heating your swimming pool!
How efficient are Water Source Competition swimming pool heat pumps?
Swimming pool heat pumps don’t have a simple efficiency number to work with. Their efficiency is measured by Coefficient of Performance (COP).
WOTAC and Competition swimming pool heat pumps COP ranges from 4.42 - 5.6.
This means that for every unit of electricity that you put in to run the compressor you will get 4.42 units of heat out of the swimming pool heat pump.
