I have gas heat baseboard hot water heating and some baseboard units don't get very hot while others do. I heard that I may need to bleed my pipes. How do I do this?

"Bleeding the pipes" refers to venting the air out of the heaters, this is accomplished by losing the top pipe connection just enough to allow the air to escape from the heater and then retighten the connection. Hope this helps, Mike

Can this be done while the boiler is on?
