I just got an unsolicited e mail on how to save and monitor electricity.
Seems the object is to sell you monitoring devices.
Anyways, one mentioned tip, which I have heard before, is to turn down your geyser temperature.
Energy can not be destroyed only changed from one form to another I seem to remeber from school or something....
Lets say the thermostat is was set set to 60 deg C and now turned down to 40.
So, assuming I like my bath and dishes at 30 deg C, always use the same amount of water to do the same, I will just use more hot and less cold water in my mix, right?
That means that although I will heat my water up to a lower temperature, to replenish my hot water, I will be heating a larger quantity of it.
IMO, all losses through pipes and geyser walls being equal, I would not save anything.
