Atmospheric Vent Gas Water Heater

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.

 

Power Direct Vent Gas Water Heater

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 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.

 

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.
