The Raypak 009235 P-R406A-EP-C #59 Digital Propane Pool & Spa Heater is Raypak's largest high-altitude propane platform, delivering a 399,000 BTU input through a copper heat exchanger and rust-resistant polymer resin headers. Factory-calibrated for the 3,000 to 4,999 foot elevation range, it delivers proper combustion and consistent heating performance where standard sea-level-rated heaters underperform, making it a strong choice for large mountain and high-desert residential pools and light-commercial applications.
Built with a corrosion-resistant, wind-resistant "pagoda top" cabinet design finished in PolyTuf powder coating over galvanized metal, the 009235 is engineered to keep operating reliably in exposed outdoor installations. The copper heat exchanger delivers efficient heat transfer, while polymer resin headers with stainless steel tube sheets prevent the rust staining that plagues older cast-iron and bronze designs. An automatic bypass built into the header supports flow rates up to 125 GPM.
A microprocessor-based digital thermostat with LCD display simplifies temperature setting and startup, and continuous self-diagnostics display operational status and service codes to speed up troubleshooting. The built-in Unitherm Governor automatically regulates water flow to keep the heat exchanger above 105°F, reducing condensation-related wear.
