Aquatherm heat pumps are rated by E.T.L. an independent testing lab for electrical safety, B.T.U. output and C.O.P. efficiency.

• Every kilowatt used to operate an Aquatherm pool heat pump returns 5.4 to 6.3 kilowatts worth of heat.
   
• Therefore, every $1.00 spent to operate the Aquatherm heat pump returns $5.40 to $6.30 worth of heat.
• Every $1.00 spent to operate a gas type pool heater returns only $.80 worth of heat. The other $.20 is wasted up the exhaust.
   
• Other heat pump types return $4.60 to $3.10 worth of heat for every $1.00 spent.

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. A pool heat pump can be charged with refrigerant in such a way that will increase the BTU output at the "optimum" or "easy" weather conditions but, the efficiency (or cost of operation) will be sacrificed, especially in colder "tougher" weather conditions. A unit with a C.O.P. of 1 point less can cost 20+% more to operate than the Aquatherm.

Operating efficiently during colder weather conditions is "where the rubber meets the road" so to speak. Aquatherm designs their heat pumps to obtain the maximum BTU, but only at the very highest efficiency possible in a wide range of weather conditions.

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.

Longevity and Maintenance

Aquatherm heat pumps will last between 10 to 15 years or more. Because heat pumps are a mechanical device with many moving parts, they require periodic service by an A/C technician.  Aquatherm's warranty in Florida is a 10 year factory warranty with 5 years full coverage. Please call for details on the warranty for outside the state of Florida.
