We are moving to a cottage that at present has economy 7 . Can someone tell me if this costs less for all the household appliances through the night or only for Storage heaters and water tank?

Are they on a separate circuit than the other electrics in the house ?
We had planned to go onto economy 10 to utilise afternoons for washing machines and driers to save money during the 1pm to 4pm economy period. Many thanks in advance . Lesley

Simply Build It

The very old system had two meters but I think all modern systems use a single special meter to supply everything in the house. Because peak electricity costs more with economy 7 can’t see any board leaving duel meter system in. There is very little one can plan to run off peak, Washer/dryer, domestic hot water, and central heating. The old brick type radiators were a little useless as near impossible to turn off so retaining the heat for evening but the new wet system with a large cylinder which is well insulated so will store heat until required and also allows solar power to be added to system works well but finding a location to site the very large tank which is heavy can be a problem. And the system is not cheap. I had considered one using gas as it gives instant hot water at mains pressure great for showers but got old boiler running again and at over £2000 for the whole system I considered the money saved would me minimal considering £2000 invested at 5% gives £100 per year it would need to reduce my bill by 80% to pay for it’s self in 20 years. Oh the salesman give nice figures but missed out the money £2000 would generate if invested.
All best Eric

Firstly when economy E7 kicks in at night the whole house goes on E7 or should do. The same applies if a new digital meter is installed but no clocks (Teleswitches) etc. A pic would help?
