Best hot water tank?
I plan to install a hot water tank. At present I have a combi boiler retrofitted to a house that used to have a tank but this made the pipe runs too long so you can fill a bucket with cold water before the hot flows through the tap.

Northern California braced for mega power cut
I wonder if this will make people in California (and elsewhere if they also have unreliable power supplies) look at gaining some measure of energy self-sufficiency? While the monetary costs of solar and batteries may not add up when you have a very reliable grid, I'm sure it starts to add up when you don't...…

Someone doing average UK mileage 7,100 miles should budget closer to 2,540 KWh per year rather than 1,730 KWh, a significant difference Cost per mile is also therefore not really electricity price / 4.1 but is closer to electricity…
