Looking For A New Heat Pump?
In today’s climate of ever-increasing energy costs, pool owners looking to extend their swim season want maximum efficiency from their pool heater. An Aquatherm Heat Pump takes heat from the air instead of burning fossil fuel like a gas heater, and will provide more than 5 times as much heat per dollar spent when compared to an average gas heater or a conventional electric resistance heater. In the early 1970’s, Aquatherm/Calorex pioneered heat pump technology for swimming pools.  Over the past 30 years, our units have evolved to be the most efficient, highest quality swimming pool heat pump available today.  You can rest assured an Aquatherm swimming pool heat pump will provide you with years of economical, trouble-free heat.
