Hi there
I have a CH system in my house, not sure how long its been there, but it looks old!!
last night before going to bed, I turned the themostat down to 14-16, as normal but the pump carried on running. This the first time it appears to have happened.
The water was switched off and so was the heating. In order for me to stop the pump I have to swith off the power at the CH mains supply. On turning the system on again this morning, the same thing appears to be happening, water and heating is coming on as needed, but the thermostat is not kikcing the pump out when I turn the temp down...the pump just carries on humming and getting hot!
Is this a problem with the Grundfos pump? Do I need to get a new pump, as it seems to be overrunnning itself!!
Your comments would be very much appreciated
