economy 7 circuits

have a storage heater in the bedroom that works fine on night time electricity.
Today installed a 2nd heater in the hallway and connected it up to a 13amp fused switch that was already installed but connected to nothing. I assume it was for a storage heater that was removed before i bought the property.
I also changed a switch on a 3rd storage heater on the landing, this switch had a dial that controlled the charge instead of the dial on the heater. Changed it to a 13 amp fused switch. This worked at night the last time i used it but havent used it due to blue flashes in the swith when swithching, hence now replaced.

Now the problem is all my heaters are on, and its not after midnight. Have i missed something so obvious.

My guess is that the points you have connected the heaters to are on the normal (24 hour) supply and not on the off peak supply.

PS You will get flashes if you turn large loads on and off.

Thanks for the reply, but how would that explain the bedroom heater that was working on off peak supply before the new heaters added. From my understanding it should be on its own circuit. have 2 fuse boxes, i assume one controls the off peak supply

Not sure I know what that was, but maybe you have joined some wires together that you shouldn't have.

i.e a 24hr supply and a timed supply.


Photos of the old unit and wires behind would help
