The Pentair 460737 MasterTemp Propane Pool & Spa Heater delivers 400,000 BTU at 84% thermal efficiency - the highest output in Pentair's residential MasterTemp line.
400,000 BTU is what you specify when heat-up time matters: large pools, pool and spa combinations where the spa needs to be ready quickly, and any installation where the owner will not tolerate waiting hours for temperature. At 136 lbs the cabinet is no larger than the 300K unit, so the extra capacity costs nothing in footprint.
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.
