Please help.....new born and mom are cold.....
Thank you in advance for your help.
We have no heat in the second floor of our home. The first floor heats up fine. We had a leaking check flow valve that I replaced. I drained the entire system before repair; after repair was done, I filled the boiler up with water manually using the automatic fill valve. We have forced hot water radiators which I bled by opening the valve on top until only water come out. The boiler is set to 15psi.
From reading threads here and searching online, it appears that we still have air trapped in the upstairs loop and purging need to be done correctly. I am confused with the layout of my piping as to which valve does what.
Can you please advice on the procedure.
