Gas fired tankless water heaters, unlike tank-type water heaters, provide hot water as it is needed. When a hot water tap is turned on, a sensor detects the water flow and activates the tankless heater, which quickly raises the water temperature to a preset level.

  • Efficiency: With UEF (Uniform ENergy Factor) of up to 0.97 compared to UEF rating of less than 0.60 for common gas fired tanks.

  • Space Saving: Tankless water heaters typically wall mounted, They take up virtually no interior floor space.

  • Longer Service Life: Because tankless heaters do not store water, they are less subject to corrosion than tank-type heaters. As a result, their expected equipment life is possibly longer, typically more than 20 years, compared with 10 - 15 years for traditional heaters.

  • Leading Edge Safety: Tankless water heaters are sealed combustion. They draw combustion air from outdoor, and have low temperature sidewall venting.
