If you want to save energy, you will save a lot more by installing a fiberglass blanket around the 40 gallon water heater tank. You can buy an insulation kit for about $30-40 on Amazon. There is only about 2-3 gallons of water in the pipes, and it will cool down in an hour or so, even if they are insulated.
