A water heater is a bigger concern than most people think, especially when making your home more energy efficient. Your water heater uses up to 12% of your house’s energy.

Sadly, people spend more time encouraging others to buy new water heaters, install solar heaters, and many more instead of using the time to explain the virtues of installing a water heater timer.
