Oh, I might as well cover this while I am here.
No, tanked electric water heaters DO NOT cost much to keep the water hot. The opposite is a myth that refuses to die.
How do I know? Over a eight weeks period on a vacant home here in TV I compared sequential weeks (1 week on, 1 week off) of a water heater on 24/7 vice a timed heater. I controlled the heater remotely with a smart switch.
Conventional wisdom would have the timed heater as much cheaper to operate as there would be no cost to keep the water hot in off hours. It was, averaging one dollar and 68 cents a Month at current SECO electricity rates. That does not meet my standard of significant.
Gas or electric water heater, your call but don't think that you are getting much more efficiency without a tank. Space savings but not efficiency or cost savings.
