Air in hot water baseboard - help!
My furnace is in the center of my condo and it seems like half of my condo gets heat, but the other half does not. I suspect I have air trapped in my pipes. Plus, I can always hear the water flowing through my hot water baseboard pipes.
I do not have access to the high points of my pipes because I live in a condo building, so I can't look there for pressure reliefs.
This is what I can see in my furnace in my condo:
City water comes in a splits 1. into furnace, and 2. into hot water heater.
Then, there are two pipes coming out of my furnace.
One of the pipes had a pressure bell then a black knob valve and then goes into the wall.
The other pipe comes out of the furnace and splits in two: 1. to a reducing valve then a backflow preventor and then through a red knob valve. 2. the other branch goes to a red knob spigot and then through the wall.
How can I purge the air with the setup I've got?
