Polaris High Efficiency Water Heaters From reliable and quiet performance to high efficiency ratings, Polaris High Efficiency Water Heaters from American are one of the main reasons behind the brand’s great reputation. Best Choice for Residential Hot Water Polaris High Efficiency Water Heaters Up to 96% Thermal Efficiency Submerged combustion chamber with spiral flue provides up to 96% thermal efficiency and ultra-low standby heat loss of approximately 1%. Features a high-grade 444 stainless steel tank with brass connections for years of dependable, trouble-free service—no anode required. Ultra-quiet radial blower is combined with the submerged burner for whisper-quiet operation. Designed for Efficiency Reliability The quiet, brushless DC blower pre-purges the submerged combustion chamber for 8 seconds and turns off. The hot surface ignitor is energized and glows red hot. The blower turns on, precisely mixing air and gas for combustion. The mixture is forced through the metal fiber burner and is ignited by the hot surface ignitor. A blue flame is evenly distributed across the entire burner, resulting in clean combustion with low nitrous oxide emissions. High Efficiency Combustion System Sealed Combustion with Woven Fiber Premix Burner Metal fiber burner is designed for clean combustion in high-intensity blue flame mode. Manufactured of refractory steel that resists corrosion. Excellent resistance to thermal and mechanical shock, even at extreme temperatures. Uniform combustion provides excellent heat transfer. Complies with SCAQMD Low NOx requirements for California and Texas. Designed for Efficiency Reliability The combustion chamber wall transfers high temperature heat from the flame to the water.
