Powerful, efficient, and reliable, MegaTherm™ pool heaters are designed for commercial, institutional and large residential pools where economical performance and rapid heat-up are required. Available in indoor and outdoor models, with twenty-two sizes from 500,000 to 5,000,000 BTU/h to precisely match any heating requirement.

MegaTherm is designed to deliver efficiencies as high as 82%. Integral finned copper tubes are rolled directly into the headers, and conformal heat exchanger baffles and an eight-fins-per-inch tubing configuration maximize combustion heat extraction. We’ve also designed MegaTherm to be simple to service. Heat exchanger header covers are field-removable for complete inspection of tubing and header passages, and the heat exchanger is replaceable without disassembly of the burners or combustion chamber.

MegaTherm is design certified to the ANSI® Z21.56 Standard for Gas-Fired Pool Heaters. (Outdoor 500–1825 units are certified for use without the addition of a draft diverter or external vent. Indoor units incorporate a built-in draft diverter and require only vent piping.) Salt water models (500–1825) are available with cupronickel alloy heat exchanger tubes and bronze headers and header covers.
