    What happens re water/immersion if replacing econ 7? 15th Jul 17 at 11:00 AM
    Hi all,

    I am thinking of replacing the heating system to electric radiators in my electric only, storage heated economy 7 1 bed flat.

    However, what do I do about heating water? At present we have an immersion boiler that heats water during the night with an on peak boost to use if required.

    If I switch from econ 7 does that mean my water will constantly heat all day this pushing the bills up?

    Many thanks for any responses in advance.

    You can stay on the ECON 7 tariff even without ECON 7 heating, and the water heating should remain the same, Why would you change anyway? Storage heaters are much cheaper to run

    Hi,

    yes would think so.

    The electric radiators will be running on full price as well, unless you have a different system in mind.

    Thank you for the info.

    My 4 storage heaters are 25 years old, 2 are not working so we need to replace the heating and I guess I have been hoodwinked!

    Should I replace for new storage heating? We also wanted more control over heating levels and I wasn't aware that econ 7 was still cheaper.

    We both work 9-5, would oil filled wall electric heaters be economical with econ 7 then?

    Thanks again.

    Hi,

    oh gosh no.

    They don't store the heat, will cost you a fortune to run.

    E7, cheap rate only runs from about 11/12 until about 7/8 in the morning, the idea being to build up heat in the storage heaters, then slowly release during the day.
    Y'all take care now.

    Your bills will almost certainly go up as you will be payng about twice as much per kWh used for heating and hot water (escept that small amount you may use for boost).

    Ok so the verdict is replace the storage with storage and keep econ 7. Which is fine but the electric radiators are so much prettier!

    I m currently paying £130pm for electric so I've no intentions of making that more expensive!

    Thanks all

    I suspect that newer storage heaters will be more efficient than the old things I have.

    That's what I hope anyway

    Biggest failing of storage radiators is their bulky design, tendency to leak heat before it's needed and overall lack of storage capacity.

    There are adverts about in the papers about super-efficient storage radiators. Without rigorous tests and reviews I wouldn't believe a word of it. Though in theory modern technology should be able to produce much better designs than yesteryear.

    There is very little in a storage heater that cannot be fixed quite cheaply.

    That's my thoughts too, but I suspect (?) that storage heaters aren't popular enough to have that 'modern technology' invested in them * whereas these fancy new/pretty 'economical' panel heaters can be made cheaply and sold expensively ... maybe!

    * it really shouldn't be rocket science to make an well insulated box to hold the heat till such time as it is needed, should it??

    It depends how you define 'efficiency'!

    Your old storage heaters will produce EXACTLY the same amount of heat, for the same consumption of electricity, as any other electrical heater - including new storage heaters. i.e all are 100% efficient.

    Any advantage of newer storage heaters will be down to their better insulation properties(i.e. not leaking as much heat) and better controls.

    As said above, it should not be expensive to repair old storage heaters.

    Economy 7 also gives you the opportunity to operate appliances in the night-time off-peak hours.

    You've all given me food for thought. I'm turning to evaluating for repair.

    I was sucked in by prettier and possibly cheap solutions as x4 new electric radiators would be roughly 1k plus fitting and are so much prettier but an increase in energy costs would be crazy.

    Do I just look for a heating specialist to give an evaluation? Or a sparky? I guess I need to get googling.

    More efficient - well, my electric is so high that I wonder if a damaged heater is pulling more electric than necessary.

    I really don't know much about these things - it took me years to work out how to properly heat the place so it wasn't toasty in the day for the cat only but cold when we got in from work.

    However I can see that oil filled or whatever is pointless as I'll be drawing electric at standard rates as opposed to drawing it cheaply and releasing it during peak.

    I need to change supplier but was waiting to see if I was changing tariff.

    Hi,

    well, I would be into the guts of the faulty heaters myself first, to see if the thermal links were melted/broken, and repair myself.

    You could get a local electrician to come check them out for you though.

    Used to be that everybody had mates 'down the pub' of different trades that all helped each other out.

    Too much IT nowadays.
    Y'all take care now.

    Indeed. I remember growing up it was always a mate who did our family repairs, whereas now my mates and I generally work in the white collar sector!

    I can get legal, HR, Teaching, finance and IT help but help for hairdressing, sparky, plumber, mechanic? No chance!
