Hi all, just upgraded my old oil burner to a condenser oil burner, I had an old pull handle valve which I used in summer to have hot water only. I’ve had this valve upgraded to a motorised valve and since I’ve only got hot water when the central heating is on, if I select hot water only the pipes get hot and the pipe to the water tank gets hot but it won’t heat the actual tank. Anyone any ideas what’s would be wrong? I’ve a small and large tank in the attic as well.
