Spent yesterday connecting a contactor to my immersion heater. I did my bit to decarbonise my consumption overnight.
I need a second immersion element in my tank to heat the lower half and I am seriously considering getting a battery system to load shift and supply my 4-7pm from the battery rather than the grid.
It won’t make me money, but should pay for itself 10 years and I think that is a good investment. Imagine if more folk did that. Could easily provide more balance to the grid.
