I have a friend who has asked me advice on his heating. The house has no gas, and has a mixture of storage heating and a wood burner back boiler driving some radiators for the rooms that don't have storage heaters. The house had economy 7 but the current supplier does not support it, though it still has a dual meter and teleswitch.
The back boiler needs a constant supply of wood which is proving onerous.
He needs a more controllable heat, he has an aging mother there too, and would like to be able to turn on the storage heaters when he needs them, which involves bypassing the teleswitch but i am not sure if the bricks in the storage heaters would delay any heat output, we are trying to do this as cheaply as possible.
We could replace the radiators with electric ones or remove the bricks from the storage heaters and bypass the teleswitch and use the same wiring?

Replace the back boiler with an electric boiler and more rads?
Any ideas for the cheapest option.

Thanks
