Should I replace my water heater?

If you have a conventional water heater with a tank, its average life expectancy is between 8 and 12 years. When yours reaches that age range, or if it’s older, it’s time to make plans for an upgrade.

Don’t wait until you are forced to replace a failed water heater. The Williams Energy plumbers will help you find the best water heater for your home and your hot water needs.

Should I go tankless?

If you haven’t heard about tankless water heaters, you’re in for a pleasant surprise!

With tankless water heaters, you can save up to 40% on your water heating energy costs, because a tank of water isn’t having to be maintained at a certain temperature. Only when you are using hot water are you using energy.

Tankless water heaters have a long life expectancy, but should be maintained as per manufacturer recommendations.

Tankless water heaters generally take up a smaller physical footprint so you will gain some space in the basement area, or wherever your tank is located. You will not need to change out other domestic water piping when going tankless so it’s a pretty easy changeout.
