How long a water heater lasts depends on how well it is maintained and the type of water heater. Traditional tank storage water heaters can last between 10-15 years, and tankless models can last 20 years or more. Signs that your water heater needs to be replaced include odd sounds emanating from it, inconsistent or no hot water, discolored water, visible corrosion on the tank, and the water heater leaking. If you see any of these signs, it’s time to replace your water heater.
There are several reasons to consider early water heater replacement. Waiting until the hot water tank stops working will leave you without hot water until a replacement is available. And, replacing it before it fails gives you time to research water heaters that might save you money, energy options such as gas, electric, or solar-powered water heaters, or you might decide you want to go tankless.
