 Well, what I would do is I would shut it off kind of after you're done with your evening cleaning tasks because the water will stay warm for a while. So if you like to shower and bathe at night, whenever that part of the evening is done, that's when you want to shut it down. Then bring it on about an hour before you wake up in the morning. If you leave to go to work on a regular basis, you can turn it off while you're away at work. But if you're home or you work from home and you need it during the day, you might have to skip that cycle. But the key time to have it off is in the middle of the night.
