Re: "Smart" Water Heaters What Do They Do Different?
Don't know much about those units.
Technology is a wonderful thing --- however --- with that comes the complexity and more components that can create issues on their own ----- adding to the cost of the equipment and subsequent repairs.
Simplicity many times is a wiser move. One rule that stuck with me from college was the K.I.S.S principal ( Keep It Simple Stupid ).
If the water heater is idle when no one is home to use hot water but is still trying to maintain the temperature ( through losses ) then it's a waste of energy.
With an electric water heater by ensuring the tank is well insulated and having a timer to diconnect the power during the day when no one is home would save energy. Having the timer connect the power shortly before you get home makes more sense.
