All of a sudden my economy 7 is not coming on overnight for the immersion on my water tank. I have a storage heater in the lounge which is coming on for econ. 7. so the econ 7 is timed OK (i live in a shared flat and the timing of it is controlled externally) I assumed the lower immersion heater was gone and it has just been replaced with a new item, however it still does not work, i have no cheap electricity to the boiler overnight. The issolation board is not tripped for the heating so this is OK. Anyone have any ideas,
thanks
