Water Heating

Water heating is the second largest energy expense in your home, accounting for about 18% to 25% of your energy use. The average family spends between $400 and $600 on water heating each year. As a result, employing energy-saving strategies and choosing an energy-efficient water heater can help save you money.

Water heaters have a life expectancy that varies from 10 to 20 years. Periodic maintenance can extend the life of your water heater and minimize efficiency loss. To make sure you have enough hot water when you want it, calculate your household’s peak-hour hot water demand and use that to determine what water heater size to get.

For Lowering Your Heating Bills

Install low-flow showerheads and faucets.

Turn down the thermostat on your water heater and set it to 120°F.


Fix any leaks; even one drip per second can cost up to $1 a month.


When replacing exhaust fans, consider installing high-efficiency, low-noise models.


Follow the manufacturer’s recommendations for ways to insulate your water heater tank and pipes.
