Simple To Understand 7-Day Timer

I'm sorta worried about an 1875 watt tungsten load inrush. Theirs is on a 20-amp breaker. When the power blinks the thing loses clock time reference. Why they make AC timers without a battery clock backup is beyond me
I use a 12-volt timer for my own stuff. But that would entail using a battery. An a 30-amp rated SCR.
Mrs Reese wants hot water ready for 7-9 AM and again from 5-9 PM every day. I have a 20-amp motor-rated light swtch I'll put downstream from the timer. A motor driven irrigation timer sounds good-if re-setting the clock proves to be easy. Turn off power switch the spin the dial by hand to match dial hour of the day to a wristwatch.
Leaving the hot water on all the time adds over a hundred dollars for a 60-day billing cycle.
Timers down here are ridiculously hard to find and expensive. Like 200-dollars for a 30-amp device.
In Las Penas my gas heater is wrapped with 6" of fiberglass. Also not available here.
