Removing A Radiator

fast pasquale

So I have a boiler. It's a two pipe system. There are no vents on the radiators. So Im guessing this is a hot water gravity system?.. Anyways... I have the 2nd fl bathroom gutted and need to remove the radiator for a few weeks. I believe the supply pipe is 3/4 inch and the return is 1/2. What does this entail?? Can I just shut the system off.. wait for the radiator to cool off and back off each union and then cap it??...or is there more involved than this.. Thanks so much!!

You'll have to bleed off the air in the system when you fire it back up, but that's about it.

I would tie the 2 together with a bleeder valve to let the air out.

He's saying that in addition to just connecting the two "ends", but a tee in that new pipe with an auto-bleeder to make an easy spot to get the air out. Might not be a bad idea, but you also might not have an aesthetically good place to do that. Not really a requirement anyhow. The more places you can bleed from, the easier the bleeding job is. No big deal either way.

You talked about capping off the ends, but that might not be what you need to do. If you have steam, you'd cap both ends. If you have a hot water monoflow tee system, you'd cap both ends. If you have 2-pipe hot water, then you'd cap both ends. If you have a loop system, you'd connect both ends with a short piece of pipe, or nothing on that loop will work. You're gonna have to puzzle on your system a bit to figure out what you have. Since you said 3/4 in and 1/2 out, you're likely on 2-pipe or monoflow hot water, but double checking would be a good thing.

I have a 2 pipe steam system. I have a boiler with a site tube. It doesn't have vents on the side of the rad's.
