Baseboard is cold


Hello. I have two rooms that are not getting hot in my house. I opened the bleeder valve on one of them, but no air or water will come out. The other room I can not open the bleeder. I can hear water running through the pipes down in my basement. I am assuming there is air in the pipes. I did remove a baseboard in my basement the other day. I capped the two 1/4 inch pipes right where they tee off the 1 inch pipe. I am guessing that's where the air came in? I have no idea how to get the air out of the pipes if I can't open the bleeder.

Thanks

There may be insufficient water and/or insufficient pressure in your system.

I don't know how to prime/pressurize the system correctly so you would need to see the instruction manual. There has to be an expansion tank (generally near the furnace) that is also properly pressurized since water does not compress.

Usually you need to go back and forth, let a little more water into the system, then let a little more air out the bleed valve(s), and so on.

YOu will never get all the air out of the radiator or baseboard whose bleed valve doesn't work. You may get some heat out of it eventually but less than for other radiators.

You either have not enough pressure ( it should be about 15 lbs) or you have frozen pipes.

How to tell the pressure of the pipes? The baseboards worked before I removed the baseboard in the basement.

What did you do after removing the baseboard ?
Did you connect the 2 pipes together that were at either end of the baseboard ?

I would suspect that if things got re-connected properly that one of two things has occured. One, you have air in that loop and two, the auto feed valve is not feeding.
