Water Heater Through Wall Vent

The direct vent water boiler is another type of water heater venting that you should know.

Water heater through wall vent. The vent consists of a vertical or upward sloping vent duct that typically ties into a common vent. This water heater is found in different homes. Hot exhaust from the water heater naturally rises up through the vent and into the air outdoors creating a draw that promotes this upward airflow. Exceptions may be made for non combustible walls such as solid masonry.

Single wall vent pipe cannot pass through any interior wall. If it is a natural vent type water heater you can not vent it through the side wall it has to vent above the roof. The difference is that a power vent water heater pulls in combustion air from the space. Instead both systems typically expel exhaust through a pipe that runs outside through an exterior wall.

The atmospheric water heater is very common. That includes tankless models. Most sidewall venting units include a draft inducing fan that may produce objectionable noise. Oil side wall vent systems tjernlund corporation provides ss2 sideshot sidewall vent systems for oil fired heating boilers furnaces or water heaters.

How important is noise in this case. The equipment includes a multi walled plenum that uses outdoor air to cool the exhaust gases as they pass through the building wall and can be installed with zero clearance to combustible materials such as wall studs or siding. The system works solely through natural convection based on the principle that hot air rises. Single wall vent pipe cannot be used for water heaters located in attics and may not pass through attic spaces crawl spaces or any confined or inaccessible location.

Direct vent water boiler. Standard water heaters the most common type often use a method known as atmospheric venting.
