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.
