Just looking for some advice. We recently had a new storage heater installed (Stiebel-Eltron SHS 3000 HHR) On the wall before was a flat panel electric heater. Currently it's been in for over a week but doesn't charge just overnight, At the moment it keeps charging both during the day and night and is using a lot of energy. When the Electrician installed it he assured me because it was a newer model it would know when to switch on and off to charge... But that is not the case, he has wired it into the wall but had not connected it to a separate circuit or to the E7 Meter. Wondering what I can do about this as it's costing a lot to run. Thanks.

    Do you already NSHeaters, are you currently on an E7 tariff ?
    Or
    Have you replaced a Panel heater on 13a socket demand day rate with a NSH 13a on demand day rate ?

    NOTE: if you put any NSH on a 13a socket, its not supposed to work that way. It, If it's wired to 13a it will indeed work 24/7.

    Unfortunately this is our first of 3 that is getting installed... I do believe it has just been installed into a standard "circuit?" (If that's the word) Currently it's using over £5 a day, it doesn't sound much but that's just for 1 radiator which isn't great. Unsure on what to do at this point and the Electrician doesn't seem to understand
    The point of storage heaters after I've explained it has to be wired directly to the meter.

    Sorry, yes I am currently on an E7 tariff. I used to use around 80/20 split (night/day) but now it's more 30/70.

    From the Stibel web site -  "However, the SHS storage heater can also be installed as a freestanding heater."  So your electrician is right  but it's bad advice .

    Get your electrician back and wire to the off peak circuit

    Never pay on an estimated bill

    The heater doesn't need to run on E7, but YOU need it to run on E7. 
    The comments I post are my personal opinion. While I try to check everything is correct before posting, I can and do make mistakes, so always check official information sources before relying on my posts.

    How old is your house?   -  In earlier days the E7 supply had a an entirely separate meter that was 'Hard Wired' to the S/Rads and Immersion tank ( No plug sockets that the consumer could use for other things )

    The modern set-up has a single meter that switches from Day to Night rate, and to set the heaters/ hot water to only come on at Night, Time Switches have to be installed on each heater or a dedicated circuit for them

    Your heater needs two supplies - a timed E7 supply to store the overnight off-peak energy and a 24/7 supply for the fan, controller and auxiliary heater although I guess it might be possible to use a single supply and then configure the heater controller to only charge during the off-peak period - possibly by the installer using the contractor access facility. You nedd to get your electrician back to sort it out

    It's designed to that it can operate with one 24h supply, but it needs to be programmed correctly.   If you don't have an E7 circuit that's switched by the meter, start by finding out your E7 cheap rate times.  Don't rely on the internet, dial 105 to find out and make a final check by watching the meter switch over at the start and end.

    Referring to Page 19 of Matelodave's manual, these parameters MUST be set correctly if there's only a 24h circuit:-
    • P15 set to 3 so that the heater 'shadows' the meter's cheap rate times;
    • P19 changed to the cheap rate start time (unless it's midnight); and
    • P20 changed from 8 to 7, otherwise the charging period will continue for an hour in the morning at the expensive day rate.
    Note that there's a BIG problem if you're in South East England where the cheap rate times are 2230 - 0030 and 0230 - 0730.  Presumably Germany doesn't have split timings: the heater can only be set to start at a certain time and charge for X hours.  If you're in the South East, the heater needs a 24h supply for the fan AND an E7 switched supply for the bricks, unless you can persuade UK Power Networks to give you an uninterrupted seven hours.

    If you're confident, Page 20 explains how to change these parameters.  But if you've paid an installer to do the job you may wish to call them back and finish the job !

    Unfortunately From what I've read up it isn't an older style meter where there are 2 separate inputs/outputs? It just switches between a day rate and a night rate. From what I can tell I don't think my landlord will pay for him to come out and re-wire it in properly.... Would it be better to get portable oil heaters ? Woken up this morning and the heater has charged itself to 100% using £5.50 worth of Electric 😮

    Does anyone know where I stand in terms of the landlord having to pay for that? Obviously he's done his part and provided heating but now if the Electrician says he can do it, Will I be charged?
