Storage heater advice.

    I was thinking of installing one of the Dimplex Quantum storage heaters in the sitting room for when I'm off shift and home all day, they are supposed to be one of the best and got great reviews for their ability to retain heat and also due to their excellent flexibility and control.

    I have Oil boiler, now the reason for doing this was to benefit from Night rate electricity which I have for the electric car.

    I could also install one in the hall which needs another radiator.

    Currently the car pulls about 3.5 Kw ( or 6.5 with a faster home charger) and the storage heaters about 1-3 ? The issue is that my next EV will have a larger battery and I may have to upgrade the home point to 7 Kw.

    This could put me above the supply limit to the house, and I usually have the washing machine set to come on then too. Guarnteed to put me over the limit with 7 Kw EV.

    We have a gas fireplace too , good but not cheap to run, runs on bottled gas.

    These storage heaters are not cheap I know on top of that installation.

    What do ye think ?

    :D due to their excellent flexibility and control.:D

    An S/H is a yoke which you preload with heat without knowing what the weather next day will be, so IMO, its the wrong answer.
    Do the math

    X hours a day at say 20 cents a kWH for Y days for say an oil filled rad
    versus
    the S/H math at 7 cents for think you really can't control, will be a fixture in the room and can only heat.

    I see they are nearly a G so the payback will be horrendous

    It seems to me you need to time shift high grade energy at a cheap price so perhaps look at a battery.
    If the G/F is open, then invest in a glass fronted one and reduce the heat loss in the room

    The quantum heaters keep their heat much longer and release it at a time you determine , it has a few programs, home all day and one where you set the time to have the house warm etc.

    Technology does move on from the bricks and asbestos heaters of the past.

    A battery is also quiet expensive with a finite life but definitely an alternative when costs come down enough.

    I also have the EV which could charge at night and provide electricity if we were allowed have the same system they do in Japan.

    The Gas is obviously the cheaper alternative in the shorter term. My Goal is to move further away from liquid fuels which I obviously can't at the moment in total.

    Ideally if costs were right and we had a feed-in-tariff I could install wind and solar PV and send all the excess to the grid and buy it back when I need or install a wind turbine and any wind can power the storage heaters in night + charge the car, run the house or provide heating to other heaters , all expensive options currently.
