Hello,
My name is David and I have a boiler problem I was hoping to could help me work thru?
I have a peerless Natural Gas boiler (boiler number mmw-115-wc, serial number mmw-18429) and it doesn't stay heating the 2 bedroom apartment that its in. I have check the gas it runs the pilot light stays on and light the fire at 180 degrees. And shuts off at around 220 degrees the motor runs and circulates the water in the pipes. The valve connected to the expansion tank works when I manually press it (it takes both hands though. Is that normal?) the expansion tank could be bad because I can't seem to charge it with air (12PSI) but I did grain it completely and reinstalled it. I filled the pipes with water and purged the air the little automatic air valves open and close once and a while with air only. and the boiler psi fluctuates between 12 and
20 PSI. Yet it still runs out of water and the heat stops. What should I check to make sure it adds water when it needs it? Is the expansions tank bad is? And if it is would that prevent it from adding water when it needs it?Thanks for your help.
David
