Hi all.
We have a hot water tank with a dial on the side ranging from 40 degrees to
80 degrees, what would be the best setting for economy as our gas bills are enormous for some reason about £140 a month. We had a Micro Glow-worm 80FF boiler two years ago.There is also a switch on the wall with a cable running from it to a small black box which has a large copper pipe running through it. I assumed this was an immersion heater and turned it off at the switch. How do I know if it is an immersion heater and should I have switched it off?
Sorry to sound thick but I know nothing about central heating etc.
Any help appreciated.
Thanks
