Hi,

Our house had electric heaters with Economy 7 installed back in, oh -
the 70s. It was bloody expensive to have installed and this was back
in the days when the nationalised electricity companies treated you
like dirt and told you what you were having. Anyhow, basically, we
have a system which controls our heating by switching the heaters on
at 1AM and switches them off at 7AM.

In the night, during the winter, the house is warm.

In the day the house gets cold very quickly and there is no way to
turn the heaters on. The heating is controlled by a black box with a
clear plastic cover over it in which there is a metal clock type
mechanism with 4 pins in it. I assume that, if I had the cover open,
I could move the pins around and get it to change so that the heaters
came on for, say, a couple of hours during the day as well as the
usual night-time. Can I do this?

However, can I have a different control box installed so that I can
set the heating to come on at night plus have some control over the
heaters during the day?

Thanks,


John.

You can't *legally* change the times at which you receive off-peak
electricity.

If you really want to keep storage heaters (which - in my opinion - are an
invention of the Devil!) you can get modern ones with much better insulation
and output heat control - along with booster fans connected to the normal
supply to get heat out during the day.

If I had them, I'd throw the lot out and put in a decent gas-fired system
with radiators. Not only is this much cheaper to run, but it is also
infinitely more controllable - and provides heat when *you* want it - not
when your supplier says you can have it!
