ProLine XE Polaris 50 Gal. High Efficiency 10 Year 130,000 BTU Natural Gas Water Heater

This Polaris high efficiency has a condensing design that operates at up to 96% thermal efficiency which saves money on operating costs compared to a standard 80% efficient gas water heater. The helical internal heat exchanger keeps hot combustion gases in the tank longer to extract more heat into the water. The Tank and helical heat exchanger are constructed from 444 stainless steel for excellent corrosion resistance without the need for an anode.|Whisper quiet operation with an ultra-quiet blower and burner to minimize noise|Power direct vent design vents with PVC, CPVC or polypropylene (solid core only) though a sidewall or roof|Advanced electronic control large touchscreen display offers precise temperature control and advanced diagnostics|Ultra-low NOx enhanced ultra-low NOx burner complies with SCAQMD Rule 1146.2 and other air quality management districts with similar requirements for NOx emissions of less than 14 ng/j|Fully serviceable from the front 2 front access panels expose all serviceable parts|Side mounted hot and cold recirculating taps|CSA certified and ASME rated T&P relief valve|Design certified by CSA International according to ANSI Z21.10.3 - CSA 4.3 Standards|Meets UBC, CEC and ICC national codes|Meets the thermal efficiency and standby loss requirements of the U.S. Department of Energy and current edition of ASHRAE/IES 90.1|10-year limited tank and 1-year parts warranty
