I have seen all sorts of methods including large contactors which switch on banks of storage heaters and also seen the time clocks working these get the time wrong and cause huge bills. Where I live now we have gas so don't see the split tariff meters much but do see them enough to know one has to be careful. So we have seen the white meter replaced with a single meter and it is up to the user to set the time not the DNO when items are used the DNO only sets the time when the charge changes. But this was a problem with items like a washing machine or tumble drier which you may want to run over night but also at times during the day. Many years ago we had the white meter and items connected to that meter only worked at the set times. You could presumably have any kind of set up you wanted, but it just got too complicated so I stopped bothering.Įconomy 7 is a tariff not a system. With our set up any electricity drawn during the Economy 7 hours was charged at E7 rate, even if not from the dedicated E7 supply. I sometimes wondered if special timers existed that had independent clocks, so that either heater could be programmed to come on at predetermined times. The problem with connecting an ordinary timer into either circuit is that there is no continuous supply to keep the clock going - if the Economy 7 is off then the clock stops.

So there could be circumstances where one wanted to heat only a small amount of water (but by Economy 7), or a full tank of water during the day having already used a tank-full of Economy 7 heated water - eg lots of early morning baths or washing. That was useful in winter when the main heating was by a solid fuel boiler. It could also be used if the Economy 7 heater had been turned off because we only needed a small amount of hot water, not a whole tank.

The upper one was intended to give a manual boost to top up hot water if it had cooled or much had been drawn off during the day.
When I had a dual-heater water tank the main (lower) heater was connected to the Economy 7 supply and the upper heater to the ordinary supply.
