PENTAIR MASTERTEMP 461021 ASME LOW NOX NATURAL GAS POOL & SPA HEATER – 400K BTU, CUPRO-NICKEL HEAT EXCHANGER
Heating Capacity: 400,000 BTU
Thermal Efficiency: 82%
Fuel Type: Natural Gas
Heat Exchanger: Cupro-Nickel (Heavy Duty)
Certification: ASME
Weight: 149 lbs
Emissions: Certified Low NOx
Application: Commercial
The Pentair 461021 MasterTemp ASME HD Pool & Spa Heater delivers 400,000 BTU in the most heavily specified configuration Pentair offers in this line - ASME certified with a cupro-nickel heat exchanger.
Both specifications earn their place on a demanding commercial pool. ASME certification satisfies code for the pressure vessel. The cupro-nickel exchanger handles salt-chlorinated water and the aggressive chemistry that comes with high bather loads, where standard copper corrodes and fails early.
The trade is 82% thermal efficiency against 84% for the standard copper version - a fair exchange when exchanger replacement on a commercial unit costs far more than two points of fuel efficiency.
