Steam Heat – How much pressure?
Quick question – what’s the normal pressure expected in a steam boiler?
I wrote earlier about my one-pipe steam boiler (oil to gas conversion) with an additional hot water loop on it to the kitchen where the pressure valve was popping off when the system got warmed up. I’m having trouble getting a plumber who knows anything about steam heat, this being the plumbing/heating busy season and all… Plus I’m worried that the next guy is going to tell me that it’s new boiler time. It’s like not wanting to go to the doctor because you think you have cancer…
The pressure in the system builds up to 13 or 14 on the gauge (PSI, I’m assuming) before the pressure relief valve blows off. What’s normal for this type of system? Is the valve defective, or is the pressure getting too high? I’m trying opening all my radiators full bore to see if that helps.
Any suggestions greatly appreciated,
