Yesterday morning the radiators were on timed, the ones upstairs were hot, but downstairs just luke warm. Turned the heating off and tried again at lunch time, and both upstairs and downstairs came on hot. Last night i bled all the radiators in the house then turned the heating on, there was a low humming noise coming from the bathroom cupboard where the pump is, but all radiators remained hot. This morning i had the heating on timed, the tops of the radiators are hot, but the bottom are cold, and there was a noise like a bag of spanners coming from a radiator downstairs so i switched the heating off, is this a pump problem? If so does it sound like it needs replaced?
Any advice is greatly received.
