Going on Vacation? Be sure to set your water heater to it's On Vacation setting. This will lower you water heaters temperature saving you money while you are away. Better yet, if you can afford the 1000.00 price, install a tankless water heating system. These tankless units only heat the water when it is needed saving you money. Also, if your house has a tub, fill it up (dry climates only) halfway. The water will evaporate and humidify your home while you are on vacation. Good for the home, furniture & indoor plants!
