Venting A Power Vent Gas Water Heater

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.

Venting a power vent gas water heater.

Gas water heater vent configurations standard atmospheric 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 power vent water heater differs from the older direct vent water heaters in terms of where the venting is found. Power vented water heaters work the same as ordinary water heaters but the exhaust gases are blown out with a small fan instead of rising upwards through metal pipes.

Natural gas or propane hot water heaters are generally less expensive to operate than electric heaters but installing a standard vent in a house. The duct may be metal or plastic depending on the type of vent system. Because the power vent uses a fan motor to draw the exhaust fumes through the flue the venting can be longer and more horizontal which will give you more. The hot exhaust gases from a natural draft water heater rise through an open draft diverter and out through a metal duct.

A direct vent system pulls in. With a power vent model the vents exhaust horizontally out of a pipe. Power venting water heaters are considered more energy efficient than a standard direct vent system and are more effective at preventing back draft air from entering the water heater. Direct vent models can only be attached to your home s chimney where the gasses are vertically expelled from the heater.
