Welcome! Here are some tips for using this forum.
Need some help here - I just bought my house a year ago, and am having a bad problem with getting air in my baseboard heating system. The entire system was bled in November, and by December the system was full of air again. It bubbles and makes tons of noise, sounds like there is a babbling brook running through my bedroom. We had it looked at and they said it was probably the automatic bleeder valve that wasn't working, so they bled the system again and replaced the automatic bleeder valve. Less than a week later we started having air in the system again, and it has gotten worse and worse. Our service company came back and basically said that they don't know whats wrong. Not sure what to do because the noise is so loud at the point it keeps me awake at night. I don't feel like the system should have to be bled every month in order for it to not be incredibly noisy, something is wrong. If the service company cant figure it out, what do I do? Its a 3 zone system, oil burner in the basement. The pressure relief valve drips, but they said that wouldn't have anything to do with the air problem... Please help!
