PENTAIR MASTERTEMP 460776 ASME LOW NOX PROPANE POOL & SPA HEATER – 400K BTU, COPPER HEAT EXCHANGER
Heating Capacity: 400,000 BTU
Thermal Efficiency: 84%
Fuel Type: Propane
Certification: ASME
Weight: 149 lbs
Emissions: Certified Low NOx
Display: Rotating Digital
Application: Commercial
The Pentair 460776 MasterTemp ASME Propane Pool & Spa Heater delivers 400,000 BTU at 84% thermal efficiency in an ASME-certified vessel - the largest commercial-duty MasterTemp, running on propane.
ASME certification is what separates this from the residential MasterTemp. The pressure vessel is certified to ASME standards, which most commercial codes require for hotel, club, municipal, and HOA pool installations. Propane fuelling covers sites without natural gas service - remote resorts, rural clubs, and facilities off the gas main.
At 400,000 BTU it heats large commercial bodies of water quickly, and at 149 lbs it stays a manageable install. A rotating digital display can face whichever way the unit is oriented on the pad, a built-in manual gas shutoff simplifies service, and the rustproof exterior handles weather and pool chemicals.
