A relatively simple question from a physics ignoramus:
I have a kitchen water heater with a 4 liter capacity. I can opt to reheat the water to 195 degrees F every time I want hot water (roughly every 2 hours over the course of the day) or I can keep the water constantly at 195 degrees. Which option is more energy efficient?
Some pertinent information:
The temperature of the room where I keep the water heater is 65 degrees F. Unfortunately I don't have a measure of the insulation of the heater.
My own intuition from some barely recalled high school physics: energy input is the same in either case.
