New smart heating using economy 7

  • We do have a very accommodating landlord :money:

    The situation was that the house isn't very well Insulated. It's well over 100 years old. It's had some measures put in for our comfort such as double glazing and thicker loft insulation. But with a baby on the way we wanted to have far better control of our heating. There are days where it could be cold one day and mild another so we could end up with stored heat overnight making the house too hot even with the vents shut.

    Then you have the opposite problem when you have a sudden cold snap and you can't get demand from the heaters until the next e7 cycle. We want to be in far greater control of the temperature and try to be ahead of the cold/heat where we can so we don't lose too much heat stored in the house.

    This is where we wanted to get advice as to whether the e7 tariff is suited for us, as the nature we will now heat our home will be different to the Storage heaters.

    Also note, such is the heat efficiency of these new heaters that we now only need 6 heaters instead of 8. So when we do need to go full tilt (which I doubt at any point) the total demand will be 12kwh instead of 48kwh.

    The irony here is that an E10 tariff might have been more suitable for panel heaters than an E7. Most people will struggle, imho, to make panel heaters work on an E7 tariff - particularly, those at home during the day. I would be looking to see if a single tariff makes more financial sense. At the end of the day, it will come down to day/night usage.

    These are the heaters we have installed. (Won't let me post links yet)

    Who does e10 tariffs? We are with edf but we are allowed to change.

    All electric heaters are about 100% efficient. The difference is that you will be using 12 kW x 24 hours a day at say 12p/kWh = £34 per day, instead of 48kW over 8 hours off-peak storage heater at say 6p/kWh = £23 per day.

    These heaters may use a bit less electricity than storage heaters, but that electricity will cost you more.

    Don't bother with E10. Stick with E7 if you want to retain your NSHs.

    Otherwise, do as I suggested in post#8

    They are legacy tariffs and are no longer offered by any supplier.

    As posted above, electricity efficiency is close to 100%. If you buy a 1kW heater from Argos or the same from Dyson (at many times the cost), a 1kW heater will put out the same amount of heat and cost you 1kWhs worth of energy per hour to run, The so called ‘efficiency’ of the smart heaters that have been installed comes from the inbuilt ability to set different target temperatures for different periods of time. You could, of course, do the same thing manually with any ‘bog standard’ heater just by adjusting the thermostat control.

    Edit:

    Having just looked at the manufacturer’s website I was expecting to find something that wasn’t there. What it says about efficiency is this:

    Quote: From Jan 1st 2018 manufacturers can only produce space heaters that are compliant with EcoDesign Lot 20 energy efficiency regulations. This means that all units must be;

    24/7 programmable and thermostatically controlled

    And have one of the following features

    Remote control via an app or geolocation. This means that you don’t wasting energy heating empty rooms.

    Open window detection

    Adaptive start control. This means that they begin heating up at the optimal time to get the room to the desired temperature at the right time.

    Unquote

    The efficiency comes from not having heat on when it is not needed; ie, zoning.

    I'm not sure that is entirely correct

    E10 tariffs are often referred to as legacy tariffs, but there are suppliers out there willing to take new customers onto an E10 tariff (sometimes in restricted circumstances)

    EDF Energy (except for customers in North East England)
    Eon
    Good Energy
    Green Energy
    M&S Energy (Now supplied by Octopus Energy)
    So Energy
    SSE

    In addition Ovo can supply E10 (in partnership with VCharge) if the customer has a smart meter

    Octopus Energy will supply, based on E7 tariff, but for 10 hours per day off peak

    Read more: https://www.which.co.uk/news/2017/05/can-you-save-money-on-off-peak-electricity/ - Which?

    There is also a new supplier, OurPower, who indicates they are willing to take on new E10 customers
    https://our-power.co.uk/eco10

    The issue, I fear, is finding a supplier who is willing to provide a new E10 meter installation. But I think at least one of the 'Big 6' listed above would if specifically requested.

    But as I mentioned previously, the OP should not bother with E10.
    There is no online switching, no online price comparison, no fixed tariffs (afaik) ... and indeed switching from the legacy supplier is never a good idea for those with such metering.

    I stand corrected. I understood that CMA report was aimed at allowing existing E10 users to change suppliers.
