You mean kill the boiler/tank at the mains/fuse? I haven't tried
I can report that when the immersion heater was in use - on a day when we were not cooking or using heating but just using shower the gas meter would register no change. Maybe 0.1 or 0.2 m3 when cooking.
Since switching off the immersion heater the gas consumption is never less than 2.7 m3 per day (so about 30kwh ) even when no cooking or heating is used.
So I'm taking that to indicate it's the supply of the hot water that is draining the energy.
thanks
