Venting Gas Water Heater Through Outside Wall

Gas or oil fired side wall power vents are provided by several manufacturers listed at the end of this article.

Venting gas water heater through outside wall.

Venting a hot water heater through the wall atmospheric water heater. Direct vent water boiler. The only other option is an electric water heater which requires no vent. 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.

Direct venting or side wall vent chimney and flue systems are a method of venting the exhaust gases from a heating appliance directly out through the side wall of a building while eliminating the need for a vertical chimney of any sort. The direct vent water boiler is another type of water heater venting that you should know. 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. All water heater venting systems use a vent duct or pipe also called a chimney or flue to bring exhaust gases from the water heater to the outdoors.

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. 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 purpose of venting a gas or oil fired water heater is to completely remove all products of combustion and to vent gasses to the outside air without condensation in the vent or spillage at the draft hood except in cases of downdraft or poor stack conditions. Single wall natural draft gas water heater vent pipe cannot be used in unheated areas like attic or garage even if only partially penetrating that space because such vent pipe installation will cause excessive condensation on vent pipe walls and compromise proper drafting double wall pipe b vent type is required. Instead both systems typically expel exhaust through a pipe that runs outside through an exterior wall.

Water heater ducts may lead directly outdoors or they may tie into a larger vent duct that also serves a gas or propane furnace or boiler in the home.
