Would it be bad to leave the electric water heater on full time like one would do in a house?
If we have sufficient electricity available we run the electric element on the water heater all the time.
If we don't have electricity (or don't have enough of it) we tend to run the gas water heater only during the day. It's loud and it's a waste of propane to run it at night.
The electric elements are cheap and easy to replace, and last reasonably long. Typically they fail because somebody turned the water heater on while it was empty. Or, eventually, because of mineral buildup, though that takes years even in places like Minnesota where the water has a high calcium content.
