Cost to get hot water from tankless coil in boiler

I'd wrap your electric water heater and just keep it on. Given how little water you're using, I just don't see it making much difference turning it on for an hour to bring it up to temp from whatever it falls to the other 23 hours and keeping it at one temp—essentially, like the equation of keeping a house at one temp vs. dropping it and having to catch up later. The only difference is that a well-insulated water heater will lose very little heat.

You know what? You are probably correct. 2 years ago $0.17 per kwh would have been an expensive delivered cost of power, at least where I was buying electricity. Now it is probably just the cost of generation. Sailing Away, make sure you are using the delivered price for electricity.
