Earth Month Tip: Insulate your electric water heater
Improve your water heater’s insulation by wrapping it with an insulating jacket and save more than $30 per year while preventing 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!
