Determining heat pump pool heater efficiency

The energy efficiency of a pool heat pump pool heater is a measure of the coefficient of performance (COP). The higher the coefficient of performance, the higher the efficiency. However, there is no standard test to the coefficient of performance. Therefore, you really can't compare the different model performance factors of a pool heat pump unless you know that the manufacturer of each model uses the same test. For example, when the outdoor air temperature is higher, the same heat pump will run at a higher coefficient of performance.

  Typically, the manufacturer tests to measure the outdoor temperature of the pool heat pump heater by 80 °F and the pool temperature of 80 °F. The coefficient range is usually from 3.0 to 7.0 and it will be a 300% - -700% efficiency. This means that every unit of electricity requires compressor operation and you get a heat pump of 3 - 7 units of heat.

Estimate pool heat pump heater costs and savings

The outdoor pool uses a resistance or gas reservoir heater to evaluate the annual pool heat pump heating cost and savings ratio.
