Conventional tank-style water heaters have a lifespan of around 10 years. Depending on the amount of use and whether or not it has been properly maintained, it could last significantly longer, or need replacement much sooner. How do you know when it's time to replace the water heater versus repairing it?
The Water Heater Is Leaking
Some water heater leaks may are the result of a faulty valve or leaking pipe. If this is the case, it may just need a simple repair to keep it operating. If the water heater is leaking because of corrosion, it may be time to replace the unit.
The Water Heater Is Slow to Heat Water
First, check that the thermostat on the water heater is set high enough. If demand for hot water has increased in the home, you may just need a larger capacity tank installed, or a tankless water heater. Slow heating can also be caused by a build-up up rust and sediment. Flush the tank to remove the sediment. If the water heater is still not heating fast enough after flushing the unit, it may be time for a new water heater.
Malfunctioning Water Heater
In some cases the water heater may be have broken parts that need replacement. A plumber can check the heating element (electric water heaters) thermostat, gas burner and thermocoupler to make sure they are functioning. Consider the age of the unit against the cost of repairs when deciding whether to repair the unit.
