If a water heater geyser(15 lit) set temp is dropped down does it help in saving power. I open both tap hot water and supply water simultaneously to my bucket for bathing purpose only. So if the temp is set high(as set by the company), it will be needed less and therefore less water is to be replaced and heated again to bring back to its set temp. On the other hand if the temp is set at lower temp, more water would be drawn from the geyser and hence more water is to be replaced and heated again in this case to bring back to the set temp but definitely to an lower temp. Which one is less power consuming? Thanks.
