deja vu? was the timer an off-peak meter?

perhaps your water heater is very old and small and poorly insulated.
how many gallons? what's the water temp at the tap just before 7 am,
vs just before 5 pm?
is your "regular stove use" making a single cup of tea every day? :-)
did you change your habits in the direction of saving more energy as
you became more interested in energy conservation? more cf lights?
do you take shorter showers, knowing you might run out of water?
did the electric rate decrease?
say your stove uses 1 kwh/day, eg 1 burner for an hour a day on average.
what's the max r-value the water heater jacket could have while saving
1 kwh/day with that twice-a-day timer?
