    NOTE: Supplementing a heat pump with a pool cover greatly enhances
    its performance, plus reduces energy costs up to 70 percent - saving
    hundreds of dollars per year in heating costs!

    IMPORTANT NOTE: Proper sizing of a unit's performance
    attributes is critical to assure total customer satisfaction.

    For a precise sizing of unit output that accurately matches or exceeds
    performance requirements, please consult a customer service agent
    to request a computerized sizing analysis, or simply complete one of
    the Online System Sizing Guides directly below.

    The average skilled handy person can easily
    manage a basic unit change-out or new installation.

    For installations which require new electrical service, hiring an electrical contractor is recommended.

    Frequently Asked Questions

    How does a Heat Pump work?

    How will a Heat Pump perform?

    Cost of Operation


    What size do I need?
    Sizing of a heat pump pool heater is based on the pool's surface area, geographic location, environmental conditions such as shading, wind, blanketing against night time heat losses, and more. Please complete, print and fax sizing form to 800-897-6527 and our engineers and consultants will prepare a free cost of operation and pool heater sizing analysis.

    Can I install it myself?
    Each model of heat pump can be installed by the handyman, although it is strongly recommended that the electric hookups be made by a professional contractor. It typically takes less than a day to have a heat pump installed and running. Installation manuals are included with each Heat Pump.

    Aquatherm Installation Manual

    Energy Rating and Efficiency
    Pool/Spa heat pumps are rated on B.T.U. output and 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.

    Aquatherm heat pumps produce 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.
