I just bought a new house and the baseboard radiators are really noisy. Gurgling whenever the circulator pump comes on. I tried bleading them several times over the course of several days. It seemed to go away for a while, then it came back.
What can I do, if anything?
I saw an episode of "Ask This Old House" where they moved the circulaor pump to the supply side of the boiler explaining that by pumping away from the expansion tank connection, the system will maintain a higher static pressure, allowing the air to remain in solution. They also replaced the old steel expansion tank with a new diaphragm expansion tank.
Could any of this help? Any other suggestions?
