EPA’s Earth Tip: Insulate your hot water heater by wrapping it with an insulating jacket, save at least $30 a year and reduce carbon pollution.
To help keep your hot water from cooling off before it gets to the tap, you can insulate the hot water piping leaving the water heater for additional savings.
And don’t forget to turn off electric water heaters and turn down gas water heaters when going away on vacation!
