| It is the heat pump in which heat is transferred to that water by taking the warmth out of the air that is created by compressing a gas. Pool and spa water circulates through the unit 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 unit 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 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, heat pumps are energy efficient and last a long time. They are not effective spa heaters because they take a long time to heat the water in the spa. Because they rely in part on taking warmth from the air, the hotter the surrounding temperature, the better and quicker they work. |
