I moved into my home a few months ago and suspect it's been quite a while since anyone bled the radiators. I've been going around bleeding them for a few days and I'm still getting a lot of air out of some of them and I'm not getting water from any. I'm not even getting water out of the ones that are completely heating up. Should I keep the valve open until water comes out (even if the air has stopped?)

Should I just keep bleeding them until all radiators stop pushing air out? or is there potentially a bigger issue?

  • What type of boiler is installed? Is it a pressurized system? – HandyHowie Jan 24 '20 at 15:24

    "I'm not even getting water out of the ones that are completely heating up." Got to wonder if you have steam rather than hot water, for the first thing. The second would be whether you need to open a fill valve on the boiler to add some water. But if it's a steam system it will be considerably different than a hot water system... If it has not had annual service, you might want to have that done and sort out this issue as well. – Ecnerwal Jan 24 '20 at 15:28
