I have a (probably original) hot water radiant baseboard heat natural gas boiler system. I came back to a cold house and a non-stop running boiler this weekend. I am not sure why this is happening, but I have a few clues as to what the cause might be.
First, every now and again, when the boiler kicks on, it doesn't have the same pleasant sound it typically does. It literally sounds like a high powered blowtorch. It is unnerving to be around it during this time. This happened shortly after my gas line was moved. I hired a company to move it so I could put in a patio.
The PSI is at 20 and the temp on the boiler states 180 -- I believe this temp is low? Air has been purged from the system and weak heat emits from the baseboards.
Weirdly, hot water tank seems to be doing the same thing. Could we have a natural gas issue? The line was last touched 6 months ago and it was fine since.
I replaced a small section of copper with pex about a month ago. I couldn't buy a small section of the oxygen barrier pex (a buck a foot for a minimum 300ft), so I just used normal pex.
I appreciate any help regarding what I may have going on. Perhaps it's time for a new boiler.
