This is what I do too. On propane, turning it off not only eliminates the noise when it fires at night (it is right under my head), it also conserves the propane.
Like Jim N said, it holds residual heat fairly well, plus is hot in short order when turned back on. If you flip the switch right when you get up, it will be hot by the time you need it.
On propane, we find that normally we turn it on first thing in the morning, off after breakfast cleanup is done, then on again as we prep supper, and off again after cleanup. The water is still more than warm enough near midnight for a quick wash before bed.

I just boil a little extra water to fill our cups a bit as a preheat before our first cup of coffee in the morning. We don't use a carafe, as I use an AeroPress, and make only two cups of coffee at a time.
