Swimming pool heat pump cost more than gas pool heaters, but they typically have much lower annual operating costs because of their higher efficiencies. With proper maintenance, a swimming pool heat pump typically lasts longer than gas pool heaters. Therefore, you'll save more money in the long run.

Selecting a Heat Pump Pool Heater
Determining Heat Pump Swimming Pool Heater Efficiency
swimming pool heat pumps use electricity to capture heat and move it from one place to another. They don't generate heat.
As the swimming pool heat pump circulates the swimming pool's water, the water drawn from the pool passes through a filter and the swimming pool heat pump heater. The swimming pool heat pump heater has a fan that draws in the outside air and directs it over the evaporator coil. Liquid refrigerant within the evaporator coil absorbs the heat from the outside air and becomes a gas. The warm gas in the coil then passes through the compressor. The compressor increases the heat, creating a very hot gas that then passes through the condenser. The condenser transfers the heat from the hot gas to the cooler pool water circulating through the heater. The heated water then returns to the pool. The hot gas, as it flows through the condenser coil, returns to liquid form and back to the evaporator, where the whole process begins again.
Higher efficiency swimming pool heat pumps usually use scroll compressors versus the reciprocal compressors of standard units.
Sizing a swimming pool heat pump pool heater involves many factors. A heater is sized according to the surface area of the pool and the difference between the pool and the average air temperatures. Other factors also affect the heating load for outdoor pools, such as wind exposure, humidity levels, and cool night temperatures. Therefore, pools located in areas with higher average wind speeds at the pool surface, lower humidity, and cool nights will require a larger heater.
swimming pool heat pump pool heaters are rated by Btu output and horsepower (hp). Standard sizes include 3.5 hp/75,000 Btu, 5 hp/100,000 Btu, and 6 hp/125,000 Btu.
The energy efficiency of swimming pool heat pump swimming pool heaters is measured by the coefficient of performance (COP). The higher the COP number, the more efficient. However, there is no standard test for measuring the COP. Therefore, you really can't compare the COPs of different models unless you know that the manufacturers used the same test for each model. For example, the same swimming pool heat pump will operate at a higher COP when the outside air temperature is higher.
Typically, manufacturers measure the COP by testing a swimming pool heat pump pool heater with an outdoor temperature of 80ºF and pool temperature of 80ºF. COPs usually range from 3.0 to 7.0, which converts to an efficiency of 300%–700%. This means that for every unit of electricity it takes to runs the compressor, you get 3–7 units of heat out of the swimming pool heat pump.
