Thought of something else. Your water heater stays on 24/7.

The only hot water I use in the morning before I go to work is to wash my hands.

If I don't get home until let's say 5. I'd need to wash my hands some more but I don't need hot water until I take my shower at 9.

So really I would be keeping 80 gallons of water hot for 23.5 hrs so I can use ~30 gallons in 15 minutes.

It's only keeping it at ~120°-140°F (~50°C) compared to 210° (99°C) of the instant hot water tank.

I have a tankless water heater so that's not a problem for me, but seems crazy thinking about it now.

Which leads me to my next thought. I wonder if they make tankless under sink hot water dispensers?
