I met my brother today and he told me something that I knew but the extent really surprised me.
The aircon shouldn't be used if there was absolutely no need. The energy consumption of the aircon can be up to 10 times that of our ceiling fan.
The storage water heater only needs to be turned on for 5min to heat up the entire tank. The water in the tank stays hot for hours thereafter, losing warmth only gradually. I think I've known the water to remain hot for up to 6-7hrs.
Leaving the ceiling fan on the whole day will not consume a significant amount of energy.
In exchange, I told him compression tights really worked, but I think that was lost on him.
