Central Heating doesn't work unless hot water stat cold

Looks like time to replace the valve head - fortunately mine is newer type with dimple on cover so it should be straightforward.

Many thanks to you all for your help

The corrosion you see may well indicate the motor shaft has leaked and caused corrosion inside the valve head!
