This was a quick and easy experiment and is not very accurate.
A scientific approach would be to repeat it several times over a longer period of time.
I am quite satisfied and a bit surprised by the results.
The big surprise is the comparison of the non-inverting air conditioner of 12000btu with that of the 9000btu inverter, with very similar results. As I said, the time was short and the results were relative. I will definitely repeat it this summer.
I had no idea and I was curious as to how much the central heating, the refrigerator and the water pump are consuming in one day. It’s OK.
Also, the evolution of the consumption of the whole house was interesting, but it should be done over a much longer period. Summer and winter.
