What with the escalating cost of electricity, it strikes me maybe I
can save some bucks by putting a timer on my hot water heater.
I could set it to heat HW only when needed (assuming Frau and I can
regulate our needs). Certainly it could be off, say, midnight to
wake-up. Maybe I am dreaming here?

I wonder:
(1) Do they make 220V timers? Are they expensive?
(2) Would I save enough to make it worthwhile? After all, there is
the cost of the timer as well as insulation to wrap to HWH itself.
(3) I would think it would consume more electricity to re-heat the
water each cycle as opposed to maintaining the heat, once hot. Am I
wrong?

Thanks
