Just a warning on point two. Decreasing the temperature of a water heater too low can result in bacteria growing in the tank.

What you could do is use a second electric water heater as feeder tank to the primary one, and only raise the setpoint above vacation-idle when electricity prices drop very low or below zero (if you're in an area that offers real-time electricity pricing).
