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.

Direct Vent Gas Water Heater
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.

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 Power Direct Vent is a very energy efficient heater which saves you money on energy costs and it’s more environmentally friendly.

FAQs
Gas Water Heaters
Why is my gas water heater condensing?
Condensate is the result of airborne water vapour being chilled below the dew point. The dew point is the temperature at which water vapour turns into liquid. Low incoming water temperatures cool the piping and the heat transfer surfaces of the water heater. When the main burner comes on, the hot flue gases turn into condensate upon contact with these surfaces. The typical home water heater will produce about one-half gallon of water vapour during every hour of operation. Condensate is often mistaken for leaking. Newer heaters will condensate more than older heaters because modern water heaters are much more efficient than their predecessors. The newer heaters utilize as much of the energy out of the main burner flame as possible. This lowers the flue gas and tank storage temperature and closer to the dew point temperature.
To distinguish between a condensing water heater and a leaking water heater:
1. Wipe up any water under the heater.
2. Turn the knob on the thermostat to the pilot position.
3. Wait 8 hours, check for water accumulation under the heater.
4. Condensation should stop when the entire tank of water is heated above approximately 115 degrees:
If no water is found under the heater, the water heater was condensing.
If water is found under the heater, check further for a loose fitting. If all fittings are tight and the tank is leaking, replace the water heater. Leaking heaters cannot be repaired.
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.
