Radiator Vents Simplified
So I want to change out all of the vents on the actual radiators themselves in the building, 12 units, 3 stories, building is in the shape of a long rectangle with two tiers(6 apartments) towards the back near the boiler and 2 tiers(6 units) toward the front furthest from the boiler. There are 5 radiators per apartment. I’ll be using Gorton vents since they are cheap where I’m at and seem like good quality. I want to simplify the process and choose 2 vent openings and match them according to size of radiator. Was thinking D’s for the larger radiators and C’s for the smaller ones like in the bathroom. Is this a bad idea or should it be ok? I’m in the process of adding bigger vents on the mainlines of which there are two, one long one to the front of the building and one shorter to the back, so the mainlines should be well vented. Any suggestions or concerns? Trying to avoid using 6 different vents if I don’t need to. Right now there are all kinds of various vents on the radiators from super old (found a vent made in 76) to super new to brandless to different brands etc. no thought was put into it as it is right now. No rhyme or reason, however, the heating has been fine but I think it can be better and more efficient. I attached a google map image of the building and mapped out where the boiler is and the 2 main lines. Again, 3 stories, 12 apartments, 2 tiers(6)apartments in the front on one main and same in the back but shorter main.
