Power vent or direct vent...

I am considering installing 3 Rheem gt199 tankless water heaters. Can someone give me any suggestions as far as power or direct vent. All comments appreciated.


it just depends on your needs as far as which one you need.

Generally, a direct vent must be next to an outside wall or be connected to a chimney that extends 2-4 feet above roof peak (all gases and fumes from the burner will vent naturally). A power vent is used when the unit is put inside the home in a closet or on an interior wall. It must have venting to an outside wall and must have a blower fan to remove gases from the water heater so they don't back up into the house.
