I realise that you are trying to inject some humour into your article about SSE’s wish list for a Scottish Energy Strategy by taking the rise of storage heaters, but I am sure you know about the next generation of high heat retention storage heaters, including Dimplex Quantum heaters, which are being installed in homes throughout Scotland.
Early indications are that they may not be making folk the financial savings that they might have expected, but they are much more controllable, and so giving folk heating at the time of day they want it.
On top of this, in areas like Orkney – where I live – energy storage (including storage heaters) is seen as a possible solution to the lack of grid capacity that has forced curtailment on onshore wind generation.
The dumping of cheap electricity into storage would seem to be a win-win, in that turbines otherwise curtailed are able to generate, and storage heater owners get cheap electricity – potentially reducing fuel poverty.
