Can you vent a gas water heater with PVC pipe?
Similar to the power vent design, a power direct vent water heater can utilize PVC piping to reduce installation costs. It is important to note that they also require an electrical outlet near the water heater for installation.
What’s the difference between power vent and power direct vent?
The difference is that a power vent water heater pulls in combustion air from the space around the appliance, then uses a fan to propel the exhaust through the vent. A direct vent system pulls in air from outside and then vents the exhaust through a horizontal pipe.
