Tankless water heaters operate differently than traditional heaters as they only heat water when it is needed instead of storing it. Condensing tankless heaters use a secondary heat exchanger that uses exhaust to pre-heat the water before it reaches the primary exchanger resulting in higher efficiencies. This condensing tankless water heater is state-of-the-art and ENERGY STAR® Qualified with an Energy Factor of 0.95. It features a power direct vent design; the primary heat exchanger is constructed of commercial-grade copper which is more resilient against erosion; a secondary heat exchanger is made of Type 316L Stainless Steel to protect against corrosion; it allows flexible venting as ULC S636 approved PVC, CPVC, polypropylene pipe or Category III/IV stainless steel venting can be used; it boasts internal freeze protection and multiple safety features; it can be used in residential hydronic heating applications; it takes up significantly less space than a tank-type water heater; and electronic ignition means there is no pilot light.
