Help Please - Night storage Heaters

I have just bought a property with Creda night storage heaters.


So ...lol. One dial controls the damper. I get that. The other dial controls the charge.
The charge dial is the bit I do not get. The storage heater comes on at 12 and off at 7. if the charge dial is set to 4, does that mean it is continuously kept at X temp equalling 4.


If so would it not be better to have the storage heater charge for less time using a timer ?


And is the charge setting a Temp setting for the bricks?
Lastly these heaters are from the 70's/80's creda 79162's , is there any benefit to upgrading?

    The charge relates to how much the heater loads overnight.

    Close the damper and try and use the charge to obtain a suitable amount of heating for your home throughout the day.
    Only use trhe damper to allow more heat out, usually late in the day, if you find it's not warm enough
    (that probably is also an indication you failed to charge/load the heater enough previously, so make suitable adjustments)

    You don't need any timer. The NSH is thermostatically controlled and will stop loading when warmed up.

    If you have a 40+ year old NSH, then consider upgrading if funds allow.
    Modern heaters are much more elegant, less intrusive and often easier to control as they are better designed/insulated to ensure heat is retained all day.

    But as an MSE'er, if they work fine and you are not bothered how they look, save your money ;)

    well I have left it on 4 setting and did not seem to get room as hot as I would like. left it on 5 last night. Will see what it is like today.(used 7kwh in electricity on 4 setting).


    I am only heating one room, the previous owners had wall mounted storage heater and a newer dimplex convection heater mounted on another wall(it has a timer and a temp stat) . So unsure if the storage heater provides enough heat.

    No, because they will drop charge (heat) into the room also, and if it is very cold outside on a particular night, then they wont get enough charge.

    The system works, just set it up and leave it going.

    Always close the damper when charging.

    Must be quite a small heater, or not very cold at night.

    Don't let the convector give out heat during the NSH's charge period, this will throw off the NSH's thermostat and force it to stop charging early. This will result in not enough heat stored.

    Use the convector sparingly as it will be using peak rate electric.

    Yes try that.

    It does take a bit of trial and error to get used to the most appropraite settings.

    Also, I found that it usually took about 2 nights for a NSH to fully charge properly from cold, and settle down, so don't be too surprised if by setting it higher, it will be too warm tomorrow.

    That's going to cause a problem, especially as the winter gets colder.
    NSH are installed throughout the property to heat the entire property sometimes with additional electrical heaters to heat other less used rooms and, as in your case, to supplement the NSH if required.

    By only heating one room, all that happens is the heat quickly transfers to the rest of the house, especially everytime you open the room door. You are, in effect, hoping 1 heater will heat your entire home.

    If the NSHs are correctly sized for the property, correctly adusted, and all used, there really should be no need to use additional heating in the room the NSH is located (except possibly on the coldest of winter days)

    ill mess around with it.


    We used the convector yesterday during the day as a top up.


    I realize the storage heater gets up to temp then stays at that temp via the charge setting, however I wonder if cutting the heating time down to say 5-7 in morning would have any benefit. As I assume the insulation is not very good on the heaters and there will be heat loss even with damper closed .

    I have left all 5 night storage heaters on, all 5 with dampers open and it was toastie warm the next day rofl 100kwh later lol

    its actually a commercial property. has a main area ,office,toilet, kitchen. office is the main working area. I have put blinds on the windows and put draft excluders on the office doors.


    I don't mind freezing when I am NOT in the office. lol


    It was originally a bank and main teller area is now open plan.

    It doesn't make much difference.

    Personally I would just put the input on maximum and output on minimum and the heat loss with the damper closed is enough to keep the room at a low but reasonable temperature until the evening. Any remaining heat in the storage heater won't need replacing the next night. It'll be cheaper than running out of heat and needing to use a convector heater to keep the room warm late at night.

    Probably give that a bash tomorrow.
    I am trying to keep my running costs down as I do not want it to cost an arm and leg lol


    having to remember to close the damper is a pain.


    I have to put a timer on the night storage heater anyway as it will not be used at weekends.

    Therein probably lies the answer ;)

    As someone has knocked the place about and made it open plan now, the original NSH presumably installed 40+ years ago is now probably too small for the enlarged space to be heated.

    If you look in almost any bank, you will usually see heaters (not necessarily NSHs) on both sides i.e. the teller side & the public side, especially with older style banks with security shield permanently in place wall to ceiling.

    It sounds like someone has even possably taken a heater out at some time .. or replaced it with that newer dimplex you mentioned.

    I would suggest you get a professional around to advise.
