: I have a building that has baseboards at the lower level and the second level has 1 large forced air return with 4 supply vents in the bedrooms. How does this return vent 2'X4' find heated air to push through these supply ducts??
: ANY help would be great!
It probably is heated in the attic.
Do you have another zone on your boiler other than the 1st floor and possibly hot water?
If so, it goes to heat exchanger in the attic or somewhere and heats the air. This is called hydro-air.
