Do direct vent water heaters need combustion air?
Power Direct Vent Power direct vents are used when the space in which you are installing a water heater lacks sufficient air for combustion and requires flexibility around the installation. The same blower is also used to release the combustion exhaust gases back outside of your home.
What is the difference between power direct vent and power vent?

When to use a power vent on a water heater?
Power Direct vent is used when indoor air quality is a concern. It draws the fresh air from outside for combustion while removing the exhaust gases with the use of the fan.
How are exhaust gases vented from a hot water heater?
Exhaust gasses are vented outdoors through a separate vent duct or through a separate chamber of the same pipe (this requires a double-wall vent duct). Direct-vent systems essentially “breathe” outdoor air, so they are not subject to the effects of backdrafting in the home.
Which is better a direct vent or direct vent water heater?
A direct vent system typically results in lower water heating costs, because the exhaust gases are vented vertically, with no extra power required as is the case with the power vent water heater. The Rheem Power Vent is a vitality effective gas water warmer with productivity of .67 EF.
Are there any drawbacks to a power vented water heater?
However, the drawback to this type of water heater is the total cost considering the blower/fan portion of the vent requires electricity to operate, the cost of the actual blower or fan, and running a power line to the fan.

Where does the air come from to run a water heater?
If so, then air will have to be brought in from the outside, usually through the use of vents or ventilation openings on the door of the closet or the wall. If this is the case, then there will have to be two vents. A top vent located within 12 inches of the ceiling and a bottom vent located within 12 inches of the floor.
