Excellent. I'll start by testing that. Job for next weekend i think. Just to complete my education do you know what the sensor is on the front of the valve? Some internet pictures show it fitted, others don't. None of them describe what it does.

You are 100% correct that I'm guesing. Is the flow valve the large disc shaped part on the left hand side? This has the differential pipes running to it? The pin hardly moves at the moment when the heating is off. It does contact the switch when the HW is switched on with the heating on...
