I have a problem with three downstairs radiators. They are the last three radiators in the chain and never seem to get vetry hot.
I have a mid-position control valve sat on top of the water pump upstairs in one of the rooms and this seems to automatically switch between water only or heating only or both water and heating...This seems fine.
When i turn the water heating off so that only the central heating is on and then turn three upstairs radiators off, the last three radiators downstairs will heat up. This is the only way to get these radiators to work.
Is my water pump knackered ???
