I used to have an 80 gal on a timer before moving here in 2020. It was the best! I had electricion put a timer on the wall for it. Timed it to come on at 5 AM and 5 PM for 2 hours. That thing was great. Always had hot water. Low cost to run it on a timer. Two people in the house (thought of resale on size).

Would love to add a timer to this 14 yr system. Will wait for the tank to RIP. Had instant in my first house here. I don't like instant... wastes 2-3 gal of water waiting for instant to reach the faucets. Would use a garden can to catch the waste for plants.
