Tankless
Condensing Tankless Gas Water Heater
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.
Discontinued: Non-Condensing Tankless Gas Water Heater
Non-condensing tankless heaters use a single heat exchanger to heat the water as it passes through it. The GSW powered by Takagi non-condensing tankless water heaters can provide you endless hot water when sized properly.
Space Saver® Electric Tankless
The Space Saver® point of use electric tankless water heater puts hot water right where you need it.
GSW builds its water heaters to be safe, energy efficient and reliable.
Many components, like our exclusive Turbulator dip tube, are available on many models and can help maintain optimum efficiency and extend tank life by reducing sediment at the bottom of the tank.
