I used to have an 80 gal water heater. I put a timer on it so it heated from 5 AM to about 8 AM and from 5 PM to about 9 PM. It was great! Always had hot water while it turned on to heat up twice a day. I really miss having a timer.

Had an instant water heater. Hated it. 2 gallons of wasted water to reach the shower toward the back of a villa.

Now have a 40 gallon water tank in a second villa. Wish I had a timer on it. Thinking about getting quote on installation of one. Currently hot water reaches master shower in the back of the Villa within about 1 gallon of wasted water .
