PENTAIR MASTERTEMP 460775 ASME LOW NOX NATURAL GAS POOL & SPA HEATER – 400K BTU, COPPER HEAT EXCHANGER
Heating Capacity: 400,000 BTU
Thermal Efficiency: 84%
Fuel Type: Natural Gas
Certification: ASME
Weight: 149 lbs
Emissions: Certified Low NOx
Display: Rotating Digital
Application: Commercial
The Pentair 460775 MasterTemp ASME Pool & Spa Heater delivers 400,000 BTU at 84% thermal efficiency in an ASME-certified vessel - the high-output commercial MasterTemp on natural gas.
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. At 400,000 BTU it recovers large commercial bodies of water quickly after heavy use or overnight cooldown.
Everything that makes the MasterTemp popular carries over: fast light-off, quiet operation, and a rotating digital display that 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.
