Im new to the site and I was hoping I could get some assistance. I did some searching and wanted to double check if I was bleeding it right.
I recently purchased my home. The boiler is practically new and is about 2 years old according to the previous owners and inspector.
When I went ahead and turned on the heat I noticed the performance of the heat in the master bedroom was quite poor, and a loud banging noise was coming from the pipes. I knew right off the bat I had some sort of air in the lines.
I have baseboard hot water and it seems to be a closed loop. There are 2 zones, 1 for the basement 2nd is the 2nd floor. It has a spirovent above the hydronic expansion tank.
There are no bleeder valves on any of the baseboards. Trust me I checked. The system runs at 20 PSI hot.
I went ahead and tried to bleed the system by talking to a few buddies for advice.
I hooked up a hose and drained the water out of the system at the same time adding water back into the system and opening the zone on the thermostat on the boiler to Max Open. The Pressure dropped around 5 PSI and was holding steady. I normalized everything up and brought the pressure to about 15 PSI cold.
Now this has improved the heating in the master bedroom and the noise in that room , but now the banging noise has moved to another bedroom.
I did not experience any kicking of water so I am unsure if I bleed it long enough or the right way.
Enclosed are pictures of the boiler from top to bottom. Your advice would be GREATLY appreciated.
