Will a timer on a water heater save energy?

Yes. With a water heater timer I believe you can extend the life of your water heater, reduce energy consumption and carbon emissions. Some timers go so far as letting you choose the times when you most need hot water like in the morning and evening. Instead of heating water all day when you arent home or using hot water you can set the timer to come on an hour before youre home and go off when you are done for the morning or evening.

This doesnt mean you are without hot water. Hot water will be stored for intermittent uses between timer settings. Some models can save you up to 30% or more on monthly hot water energy costs even.

There are several companies that manufacture water heater timers for both gas and electric water heaters.
