The Pentair 460731 MasterTemp Propane Pool & Spa Heater delivers 200,000 BTU at 84% thermal efficiency - the entry point into Pentair's mainstream residential gas heater line.
At 200,000 BTU it is right-sized for smaller pools, spa-only installations, and spillover spas where a 400K unit would short-cycle and waste fuel. At 128 lbs it is also the lightest full-size MasterTemp, which makes it the easiest to position on a finished pad.
The MasterTemp reputation rests on fast light-off and quiet operation - quiet enough to sit near patios and outdoor living spaces. 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.
