Pool heaters are available in common three phase voltages from 54 KW thru 144 KW with a one-two week lead time.
Our pool heaters have a number of advantages over the competition.

  • All of our pool and spa heaters, exchangers, and plumbing fittings are made of 304 stainless - which adds to their longevity.
  • Compatible with remote pool heater controllers

  • 316 stainless and titanium sheath elements are available as options. That alloy does add to the lead time and price but may be desirable in some environments such as extremely high chlorine content or salt water pools. The titanium sheath elements are also recommended for salt water pools.

  • Compact design that can be color matched to your pool pump if desired

  • An excellent warranty of 5 years on the heat exchanger and 2 years on all electrical parts

  • We offer a 10 year optional extended warranty on all parts for our units. Please see the cost of this option on each of the individual product pages.

  • Most common models are in stock.

  • All our pool heaters are made and tested at full power in our Southwest Florida factory

  • For larger pools we can meet any demand and will manufacture a custom heater for you. Please contact us for a consultation.
