My radiators were getting hot when I selected hot water only.
I was advised it was the motorised valve that was blocked, I changed this yesterday.
The motorised valve I took off was a Honeywell and I replaced it with a Horstmann (this being the only one I could get quickly).
Unfortunately the radiators are red hot but I now don't have any hot water.
I noticed the A & B Port on the Honeywell valve and put the new valve the same way, but will they be the same?? as the B port (C/H side) is red hot and the A port (Hot Water side) is cold leading into the tank even when the water only is selected and the heating is turned off.
Can the valve be the wrong way around or is it another problem????
