    to back it up. AquaTherm not only outlasts, but out-performs virtually
    all other makes and models!

    An AquaTherm heat pump will effortlessly raise your pool's temperature
    into the 80-90 degree range. In addition to warming the water, the
    swimming season can be extended in cooler climates by as much as
    50%, plus an AquaTherm unit performs year round in warmer climates.

    AquaTherm performs worldwide - even in cooler climates, requires little
    to no maintenance, and an AquaTherm unit typically lasts 15 - 20 years,
    often much longer!

    Operating efficiently during colder weather conditions is the true test
    of a unit’s performance. AquaTherm designs heat pumps to obtain
    maximum BTUs at the very highest efficiency possible, and in
    the widest range of weather conditions.

    Standard Feature Complete Details:

    Superior Technology – Over 25 years in development and testing,
    the AquaTherm unit provides residential or commercial customers with

    Innovation – AquaTherm’s exclusive design is the only heat pump
    on the market that incorporates a Receiver Tank with its compressor.
    This unique device prolongs the life of the compressor while protecting
    it from damage during start up, and even in cold weather operation, by
    preventing damaging liquid refrigerant from backing up in the system.

    Computer Controls – Total pool/spa automation compatibility
    is entirely integrated using Digital Logic™ Dual Thermostat Controls;
    no other add-on controls required. All-digital technology provides a
    "Plug and Play" style installation, eliminates day-to-day operational
    hassles, and makes enjoying your pool/spa combination a breeze!

    Plus, the electronics of the entire TITANIUM Series line are automation
    ready to interface with all popular third-party brands of pool/spa
    computer control devices.

    controlled key pad, along with temperature, status, and self-diagnostic
    LED readouts.

    Options include time clock overrides, hot gas defrost, 3 phase power,
    plus a heat/cool mode for chilling the temperature of naturally over
    heated pool water.

    Titanium Heat Exchanger – Patented ThermoLink™ technology
    insures state-of-the-art performance with a water management system
    specifically designed to maximize surface contact of pool water - the most important factor in determining the efficiency of your heat pump.

    Constructed with the legendary Industrial Grade Titanium Alloy heat
    exchangers found exclusively in the TITANIUM Series units; designed for
    extreme internal resistance to corrosive pool chemicals, defends against
    deterioration 100 times more effectively, plus a unique coating insures
    exterior protection to the exchanger from unit condensation and outdoor
    environmental corrosion.

    Copeland ZR Series Scroll Compressor™ – Featuring the ultra quiet
    ZR Series. Designed for heavy-duty commercial use, the ZR Series is
    the largest scroll compressor ever offered for use in residential units.

    The Copeland Corporation, America's largest compressor manufacturer,

    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.
