The Polaris® high efficiency water heater features a submerged combustion chamber with a spiral flue that provides up to 96% thermal efficiency and an ultra-low standby heat loss of approximately 1%.
It direct vents up to 120´ using ULC S636 PVC or CPVC pipe either "through-the-wall" or "through-the-roof" with an optional concentric vent kit available. Through-the-wall venting allows the Polaris® water heater to offer both forced air hydronic heat and radiant hydronic heat. Both options can heat large homes and feature an ultra-quiet blower and burner that minimize noise. The “plug-and-play” technology requires no special adjustments at initial start-up and the Polaris® heater has a high grade 444 stainless steel tank with brass connections which provide years of dependable and trouble-free service.
