PENTAIR MASTERTEMP 460793 LOW NOX PROPANE POOL & SPA HEATER – 175K BTU, COPPER HEAT EXCHANGER
Heating Capacity: 175,000 BTU
Thermal Efficiency: 84%
Fuel Type: Propane
Heat Exchanger: Copper
Emissions: Certified Low NOx
Display: Rotating Digital
Exterior: Rustproof
Ignition: Electronic
The Pentair 460793 MasterTemp Propane Pool & Spa Heater delivers 175,000 BTU at 84% thermal efficiency, filling the gap between the 125K and 200K models in Pentair's residential gas line.
That capacity suits spas, spillover spas, and smaller pools where a 200K or 250K unit would be oversized. Oversizing a gas heater causes short-cycling, which wastes fuel and shortens component life - matching output to the load is the cheaper long-term choice.
The MasterTemp reputation rests on fast light-off and quiet operation. A rotating digital display can be turned to face whichever direction the heater is installed, indicator lights show operating status at a glance, and a built-in manual gas shutoff simplifies service. Certified for low NOx emissions.
