It doesn't get any easier than this.
Simply turn down the temperature on your hot water tank.
Your hot water tank uses a lot of energy to keep your water scalding hot and really, you don't need water that hot coming out of the taps.
By turning the temperature down at the tank you will be saving on your energy consumption therefore reducing your energy bill as well as providing a safer environment for your family by reducing the risk of serious burns from hot water.
You can even take it a step further and turn the temperature on your hot water tank to 'vacation' when you won't be at home for a week or more. No use keeping that water hot when there is no one to use it.
Turning the temperature down on your hot water tank is simply a smart thing to do. So what are you waiting for? Be an EcoWarrior - turn down the temperature on your hot water tank now.
