Can a gas water heater be vented out the side of the house?

All natural gas water heaters must be vented to the outdoors to remove the byproducts of combustion.

Most of these units require zero-clearance at the sides and rear, which allows them to be installed in a small area.

Can I use PVC to vent gas water heater?

PVC is fine. As Jason mentioned, plastic (PVC or ABS) is ok to use as a venting material on powervented hot water heaters. They work by sending a huge amount of air in with the flue gases that it decreases the temperature of the exhaust going through the vent enough that it will not comprimise the vent.

Can I replace a power vent water heater with a direct vent?

Instead, both systems typically expel exhaust through a pipe that runs outside through an exterior wall. This difference in operation means that you can install a direct vent system almost anywhere, but a power vented water heater must be placed in a room with adequate airflow.

What is the difference between power vent and direct vent water heater?

Direct Vent vs. Power Vent Water Heaters. The difference between the two water heater types is combusted from the burner to the vent system. A direct vent water heater vents these combustion gases to the atmosphere, while a power vent water heater removes them with the aid of a powered venting fan.

Why do I need a direct vent water heater?
