Condensing Tankless Gas Water Heater

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. The GSW powered by Takagi condensing tankless water heaters are state-of-the-art and are ENERGY STAR^®Qualified with an Energy Factor of 0.95.
