The direct vent gas water heater looks like it has a pipe sticking out of its head. It is a gas water heater that has a venting pipe that goes right from the water heater out the side of the building or in some cases, up a chimney to a roof vent. So it “directly” vents right out of the house.
With its closed and tightly sealed exhaust system, the Rheem direct vent water heater sends one pipe through the wall outside to both draw in air for gas combustion and expel toxic exhaust. Combustion, in a water heater, is the burning of natural gas to heat water.
A gas water heater needs plenty of air for this combustion, and using air from the outside is energy efficient. The alternative would be for the water heater to draw air from inside the house, pulling in air that you just used electricity and/or gas fuel to heat or cool. With the direct vent, you avoid this added fuel use, and cost. And your furnace or air handler doesn’t have to work as hard.
Usually, if you have a direct vent already installed, you will need to replace it with the same type of water heater. However if you are just getting gas to your home, our Seattle water heater specialists can work with you to determine which type of gas water heater is needed for your location and gas line size.
