However there is a separate switch in a cupboard which is labelled "On Peak" - should it be on or off please. I have switched all the underfloor heating off on the room switches and have plenty of...

    Economy 7... two SPDs?

    Simple question. When installing a dual supply CU for a customer with economy 7 will you now be installing SPDs on both supplies? Yes, the heaters are resistive loads but they also contain electronics.

    Horstmann Economy 7 Quartz heater always 'on' - doesn't turn off according to pre-set times on clock

    Hi all, I have quite an old Horstmann Economy 7 Quartz water heating system in my flat (installed around 2007). It's been working fine until the last month, now the water heater always seems to be 'on'. The clock is set to the correct time, and even when it is the middle of the day when the...

    Horstmann Economy 7 Quartz Timer Inverted

    Hi, we have this device in our home and looks like the timer is messed up. It looks like the timer led is on when not in off-peak hours. I debugged this by just rotating the time dial and the timer led turns off for that 4-5 hours period and the rest of the day when I am turning it is on, so...

    Can I remove the Economy 7 Board?

    Hi all, I got Economy 7 and 2 consumer boards, but only want 1 consumer board as it'll look a lot tidier and save me replacing the E7 board as its very old and needs replacing. The E7 board only runs the immersion tank, used to run heaters too but I moved those circuits to the main consumer...

    Economy 7 moved to single rate meter, should it be charged at the same rate?

    I recently switched from economy 7 to a single rate smart meter. I have two fuse boards and wondered should these now be on 24hours a day and should they be charged at the same rate? I got my bill through and it looks like they are charging us at different rates, both of which are higher than...

    Economy 7 to 24hr supply.

    Is it possible to change the supply to Storage Heater sockets from Economy 7 to normal 24hr supply? Have disposed of the old storage heaters and need the supply changed so I can use "normal" heaters. However I do not want to get rid of Economy 7 fully as I have an Immersion Heater and a large...

    Economy 7 supply

    Hi All, I have just completed an EICR on a new (2017) conversion and noticed the E7 looked unusual. Is this the norm now to connect E7 to the main board feed from the meter? There is only 1 appliance in the flat requiring E7 and that's the tank with 2x immersion heaters. Both are connected...

    UK synchronisation of storage heaters and Economy 7 supply timings.

    please could somebody tell me how storage heaters are linked/synchronised with the electricity supplier so that they switch themselves off and on to coincide with the timings of the Economy 7 rate. In my case, for example, the E7 timings are allegedly 11.30 to 6.30am but the storage heaters are...

    Have to say "DIYer", but I have no intention of doing any work myself - so "Consumer" might be better. Just adding 13A spurs is my limit. I want to understand smart meters and Economy 7 in detail, before getting anything done at all. That will be after Covid, since there is no hurry. I also...
