How can I tell if my water heater needs repair or replacement?
Weโve all gotten used to having reliable hot water in our homes. Nobody wants to get caught off guard with an unexpected cold shower or failed water heater. I tend to live in the โif it isnโt broken, donโt fix itโ school of thought, but a failed water heater can cause damage to your home and property. Emergency replacement of a water heater can add unnecessary cost, not to mention inconvenience. Evening or weekend replacement or repair can lead to higher costs charged by a plumbing company.ย
Here are some signs that your storage water heater might be approaching the end of its life.
The typical lifespan of a storage water heater is 10 to 15 years, according to the U.S. Department of Energy. If your water heater is older than that, plan to replace it soon. Donโt have records of when it was installed? No problem. Find the serial number on the water heaterโs sticker or metal plate. Look up the serial number online or call the manufacturer to find its age.
Sediment or water on the floor or at the bottom of the water heater could mean its days are numbered. Sediment can be a sign of corrosion, which leads to a leak or failure.
Seeing rusty or discolored water when you turn on your faucets can be a sign the tank is rusting inside. If water is not getting as hot as it used to, it could be a sign of a failing electric element or a gas burner not functioning properly.
Odd noises could indicate an issue with the components. If youโre hearing unusual noises from your water heater, schedule a checkup with a plumber. Well-functioning water heaters typically donโt make much noise.

A professional plumber may be able to replace failing components. If you are having issues with the tank itself, itโs likely time for a new unit.
If youโre in the market for a new water heater, a heat pump water heater might be a good fit for your home. These systems are two to three times more energy efficient than conventional electric-powered tank water heaters, according to the DOE. A federal tax credit is available until Dec. 31. You can claim 30% of the project cost, up to a maximum of $2,000, for the installation of an Energy Star heat pump water heater. If your water heater is past its useful life or showing any signs of failure, consider investing in a new one before the end of the year. You might also be eligible for rebates from your state or electric cooperative.
Even if your water heater is in great shape, you can save at home by lowering your hot water use. Some easy ways to do this are washing laundry in cold water and installing high-performance aerators on faucets and showerheads to reduce the amount of hot water you use. If you have time-of-use rates, you can save by installing a timer on your water heater to prevent it from operating during peak energy use hours, typically in the mornings and evenings. It also helps lower the strain on your electric utility.
Knowing the signs of water heater failure can save you from home damage and offer opportunities to explore options for more efficient equipment to lower your electric use.
