I have a house with a few hidden radiators (the radiator is in the basement in a box and vented to the upstairs). On all of them there is a vent to the outside I assume for fresh air The problem is when the heat is off you get cold air blowing through the house. Can I just cut this vent to the outside and let it get air from the basement or was there a reason that this was important
