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.
The Atmospheric Vent is an entry-level gas heater. Air is drawn from inside the home and the exhaust is vented into a chimney or through the roof. The GSW Atmospheric Vent water heater features the Flame Guard® Safety System, which reduces the risk of accidental fires involving flammable vapours from products such as gasoline, paint thinner or solvents.
A Direct Vent heater is used when conventional chimney venting is not an option and an electrical source is not close by. The heater must be installed near an outside-facing wall as it draws combustion air from outdoors using the included 90” coaxial vent pipe. The exhaust is vented outside without a blower meaning it operates silently. The GSW Direct Vent heater is ideal for tight installations where space is at a premium.
A Power Direct Vent heater is ideal when using inside air for combustion is not an option and a longer vent run is required, possibly as a result of the heater being in a smaller room that does not have a wall facing outdoors. The air is drawn from outside using a vent pipe and a rotatable motorized blower forces the exhaust outside. The GSW ENERGY STAR® Qualified Power Direct Vent is a very energy efficient heater which saves you money on energy costs and it’s more environmentally friendly.

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.
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.
