Hi,
On the electric setting the water heater will cycle every four hours and run for about 15 minutes. That represents 90 minute of run time and for my RV about 2.1 kwh. If starting from water 'at the ambient' it takes about 30 minutes to bring the water up to a temperature for a good hot shower in the morning. There is generally enough hot water left to get me to bed time. That represents only 0.7 kwh.
I tend to leave it on if someone else is paying, but will manually turn it off if I am paying.
So when you are paying the that is a 20 cents a day savings assuming your calculation of usage is correct.
