The Pentair 460734 MasterTemp Natural Gas Pool & Spa Heater delivers 300,000 BTU at 84% thermal efficiency - the step-up size for larger residential pools.
300,000 BTU sits between the common 250K and the high-output 400K. It suits larger pools, pool and spa combinations that need faster spa recovery, and colder climates where a 250K unit would struggle to keep up in shoulder season.
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.
