A friend of mine asked the local electricity company to install a "white
meter",
Economy 7 type thing to power his night storage heaters.

The company said that it is not their policy to install such meters anymore,
and that it is all done by computer.......!! This answer intrigued me, any
idea what the chap was talking about?

With my economy 7 supply I have a single meter for the whole house with one
supply
The meter records off peak and on peak usage.

It is my responsibility to make sure that any devices that I want to power by
off peak electricity are only connected to the supply at the appropriate time
(which I do by using a time switch.)

Hmm, I have a single meter with dual rates that is 'managed' by a
separate clock close by. The clock also has a substantial switch in it
that feeds another mini CU that raidially feed the storage rads.

The rads 'only' come on during the Economy period but *everything* on
at night is charged at the lower rate *we use timeswitches on the
Washing machine, tumble dryer, dishwasher etc). I also used to run an
electric car and that was generally charged overnight.

Out of interest, had we only had the std rate, the total units used
since they fitted this system probably 15 years ago is 165439 and if
we said +AH4-5p / unit that would be +AKM-8271.95.

But of that, 93057 units were charged at the lower rate (say 2p /
unit) saving +AKM-1861.14 ?

There was a small standing charge but I think the calculations
suggested that if you had even a fridge and freezer (on 24/7) the
standing charge would be covered.?

All the best ..
