I really need help, please. My electricity bills are enormous, totalling 2,500 euros last year. After months of discussions, electricians, EDF visits, I think I have isolated the problem but would be grateful for help.
I have a new hot water heater and an old EJP box. There are three things for the hot water heater, seemingly 1 contacteur and 2 fuses. (See photo below) When I stop the fuse labelled EJP, the meter stops speeding but I also stop the hot water heater. Has anyone any advice for how to fix this, please? I would like to be more aware the next time the electrician comes.
