Hi there, I have a potterton boiler and CH system. We had a problem back in November last year where the Myson power extra valve was over-riding the controls and giving us max temperature water, even with the controls off and the front room thermostat set to 5 degrees. The valve was replaced and we thought all was ok, the heating was going off as it should with the timer and the thermostat controlled the temperature ok.
But, we just recieved a £144 electricity bill, normally £50-70 ish, and a £180 gas bill, 3 x as much as the same period last year. The only thing I can point to is this new Myson power extra valve, it seems to me that the operating light is permanently on, is that right? Any other ideas would be gratefully recieved.
Regards, Cliff
