Heating Capacity: 400,000 BTU
Thermal Efficiency: 96%
Fuel Type: Natural Gas
Heat Exchanger: Titanium

The Pentair 461113 ETi Pool & Spa Heater delivers 400,000 BTU at 96% thermal efficiency - a full twelve points above the 84% that conventional pool heaters achieve, and the highest-output ETi Pentair builds.
That gap is the whole reason to specify an ETi. A conventional heater sends roughly 16% of the fuel you pay for out the flue as hot exhaust. The ETi's condensing design extracts that latent heat instead. On a large pool or a commercial installation running long hours, the fuel savings are substantial and recover the price premium.
Pentair's Titan-Tough direct-fire titanium heat exchanger handles the condensate acidity that comes with condensing operation, along with salt and chlorinated water. At 400,000 BTU with 96% efficiency, this is the highest-output, highest-efficiency gas heater in Pentair's residential range.
