ENERGY RATING AND EFFICIENCY Pool/Spa heat pumps are rated on B.T.U. output and coefficient of performance (C.O.P.) efficiency.
B.T.U. (British Thermal Units) is the measured amount of heat output the unit will produce. The B.T.U. output will fluctuate with the outside air temperature and humidity levels.
C.O.P. (Coefficient Of Performance) is the measured ratio of kilowatt usage compared to the kilowatt output.
An Aquatherm heat pump produces between 6.3 and 5.4 kilowatts for every one kilowatt used to operate it, therefore every $1.00 spent in operation returns $6.30 to $5.40 worth of heat. The C.O.P. efficiency will fluctuate with outside air temperature and humidity levels. In 23 years of testing, Aquatherm has focused on obtaining the highest efficiency possible. The greatest value a heat pump provides a pool owner is to deliver a warm pool or hot spa at the lowest possible cost of operation.
