Looking for advice. I’m replacing 2x 40 gal hot water heaters. Both are powered vent exhaust drawing room air for combustion. They are not in a confined space. Big basement with lots of room.
Lowes delivered 2x 40 gal AO Smith with powered direct vent. This style is designed to draw supply air from the outside. Question, the current powered vent draws inside air. So do both of my HVAC units. Is there any reason why powered direct vent can’t use ambient air??
