My consumption yesterday.

seems only 3 cups of coffee, but the question has to be, can I change the use enough to line up with the off-peak times, and that seems unlikely.
So we look at power use, freezer and fridge, reasonable even through the day, the washing machine, tumble drier and dishwasher, have delay functions, so we can set those to run off-peak, dietitian tells us when to eat, OK may alter a bit, but cooking tends to be between 15:00 and 19:30 even if dinner eaten after 19:30 it will likely be cooked before then, so 8:30 pm is a bit late to eat dinner, so what can I move?
And that's the point, the only thing one may be able to do, is move when heating comes on. Last week, as sun goes down, it has been getting a little chilly, and I have started using an oil filled radiator, which does stay hot for some time. This month used 5.2 kWh, used once yesterday
bang on the expensive time. So the one thing it may help with, is under floor heating, it takes a couple of hours to heat up, so will 12:00 to 15:00 last until 19:30 well this time of the year, answer is likely yes, but as we get into winter, that will change.
