I bought a timer for my water heater. It was $28 bucks on Amazon. I set it to turn on in the morning for an hour so I can do the dishes. Then it turns off. When I want to shower, I turn it back on using my Chromebook. You can use your phone also.

It has saved me HUNDRES. Like $50 - $100 per month......LINK BELOW!
