Hi all,
I have been busy renovation a house that I bought a year ago during the winter. During the summer we switch off the heating system to conserve electricity as we are not living in the house. I removed some of the radiators during the wall renovations, refitted and bled the system. As soon as winter started I turned the heating back on before we went away for the December vacation. Now the system is making a humming noise as per the recording I attached. The system is heating up as normal. Advice will be greatly appreciated.
