Venting a gas water heater through wall.

The direct vent water boiler is another type of water heater venting that you should know. Exhaust gases are vented outdoors through a separate vent duct or through a separate chamber of the same pipe this requires a double wall vent duct. They do make two models of power vent units one is called a direct vent power vent as bob harper pointed out it draws its combustion air from outside unlike a standard power vent unit which burns its combustion air from the dwelling. A water heater using atmospheric venting or direct venting will allow the fumes to exhaust naturally by rising straight up through a vertical vent which is routed to the home s chimney or through an upward sloping vent which may be routed through the chimney or through a wall to the home s exterior.

Yes you can vent a gas fired water heater out of the wall if it is either a power vent unit. The difference is that a power vent water heater pulls in combustion air from the space. The only other option is an electric water heater which requires no vent. All solid liquid or gas fueled water heater whether they are tank type or tankless must vent through the roof unless they are direct vent.

The atmospheric water heater is very common. This water heater is found in different homes.
