Pool heat pumps are quickly becoming a more popular method for heating swimming pools and spas. Not only energy efficient, they are economical and environmentally friendly. Although their initial cost is significant they are energy efficient and save pool owners money on longer term energy costs.
Pool heat pumps work by capturing heat from outside air and transporting it to the pool's water. Heat pumps don't use gas or propane but they do run on low amounts of electricity. Although similar in function to residential heat pumping systems, those specially designed for pools are readily available.
Heat pumps are controlled by a thermostat although some systems have comprehensive digital keypads for a wide variety of regulations.
Heat pumps have different BTU outputs and are sized according to the amount of water in a pool. Those designed for in ground and above ground models can be easily found.
Heat pumps range in efficiency, which is expressed as coefficient of performance. COP ranges from 3.0-7.0 when referring to pool heat pumps. The measurement refers to the relation of inputted electrical energy compared to outputted heat. Seven on the scale expresses maximum energy efficiency.
Some pool heat pumps have been designed for pool and spa combos; others can not only heat a pool's water, but cool it as well.
Pool heat pumps will take longer to heat the water to the desired temperature. In comparison to gas or propane pool heaters they need to run longer to reach the optimum temperature. One of the other downfalls of a heat pump is that they can be costly and difficult to repair because of their complicated equipment.
Proper installation of a heat pump and maintaining water balance are important to the integrity of a heat pump. Heat pumps start at around $1,500 and go upward to the thousands. Click above to reach detailers who sell pool heat pumps.
