Swimming Pool Heat Pumps work by taking warmth out of the surrounding air by compressing a gas and transferring this heat to the water in the swimming pool.
Pool and spa water circulates through the Swimming Pool Heat Pump the same way as the other heaters, but does not pump any more heat than any other design of pool and spa heater.
A compressor in the Swimming Pool Heat Pump exerts pressure on a gas, usually Freon, and generates heat. The water is circulated through a heat exchanger that is warmed by contact with the hot gas. The gas cools from contact with the water and is recompressed and heated to start the cycle all over again.
The Freon used in Swimming Pool Heat Pumps is a nonflammable, noncorrosive gas, which makes it suited to this application. Freon does not contain the chlorine component of the Flourocarbon that makes it environmentally hazardous.
Though expensive, Swimming Pool Heat Pumps are energy efficient and last a long time, meaning that the initial outlay can be reclaimed in power savings and longevity.
Because they rely in part on taking warmth from the air, the hotter the surrounding temperature, the better and quicker they work.
Many people think of pool heaters as unnecessary expense. But in cooler areas of the country, a heater lets you open the pool earlier in the spring and keep it open longer into the fall.
In hot regions, a pool heater may allow you to use your pool almost year round. Also, the Swimming Pool Heat Pump runs at considerably less cost than many people would think.
