When do I know I need a new water heater?

If your tank or heat pump water heater is more than 10 years old, it may be time to consider replacing it. With proper maintenance, your heater should last 10 to 15 years. Check your water heater's warranty for the most accurate timelines. Lastly, if you notice the water heater leaking, making loud noises or you have a foul smell coming from the water, you should consider replacing your water heater.
