I live in a condo that has the boiler in a storage room on the balcony. The room immediately next to this storage room is my dining room. I've been trying to do things to help keep the condo warmer in the winter since I apparently have no blood. :P I noticed that there seem to be two vents between the dining room and the storage room that I don't think serve a purpose except for maybe letting cold air from the storage room come into the condo.
I've attached a few pictures to try to help explain it better. The first picture is from the storage room. I'm not too familiar with HVAC systems, but I assume that the air intake part is on the bottom and the air that's forced out is on the top. From the view in the dining room, the section of the ceiling that's lower (and blood red
) is the duct work for the forced air. The vent just below that is just open to the storage room air. The bottom vent, the lower half is connected to the air intake ductwork, the upper half is open to the storage room air.
My question is, do the upper vent and the upper half of the bottom vent really need to be there? Can I close those off to try to keep the condo a little warmer?
