Water Heater Through Wall Vent

The difference is that a power vent water heater pulls in combustion air from the space.

Water heater through wall vent.

The system works solely through natural convection based on the principle that hot air rises. The direct vent water boiler is another type of water heater venting that you should know. 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. 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 vent consists of a vertical or upward sloping vent duct that typically ties into a common vent. Instead both systems typically expel exhaust through a pipe that runs outside through an exterior wall. That includes tankless models.

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. This water heater is found in different homes.
