Considerations
Though the average life span may be more than a decade or so, replacing your
water heater about every 10 to 15 years not only ensures smooth heating of
water, but also saves energy and money. According to the Department of
Energy (DoE), heating water accounts for 13% of the average utility bill. In
order to maximize savings, the DoE recommends investing in a natural gas or
tankless water heater or investing in "green" water heating technology such
as a solar water heater or a heat pump water heater instead.
