Water Heater FAQs Every Homeowner Should Know
Not sure how old your water heater is or how long water heaters usually work well? Not sure what maintenance can be performed to prolong your water heater's life?
How can I tell how old my water heater is?
Check the serial number on the tank. The first four digits can be decoded to determine both what the month and what the year was that the manufacturer made the heater. (For example, 1010 would stand for October of 2010.)
How long can I expect my traditional tank hot water heater to work well?
If properly maintained, gas water heaters typically work for ten years.
Electric water heaters typically work for fifteen years (again, if properly maintained.)
How long can I expect my tankless hot water heater to work well?
Tankless water heaters can last for up to twenty years, which is one of the many reasons they have gained so much popularity recently. They also don’t require any annual maintenance and use almost 50% less energy than a traditional tank water heater.
What sort of annual maintenance should I be performing on my traditional tank water heater?
You should drain and flush your water heater every year. Draining and flushing your water heater is not very difficult; you will most likely be able to do this yourself.
Every three years you should also replace the anode rod to prolong the life of your water heater. To learn how to change an anode rod, see this article and video here.
Most people have a plumber change the anode rod for them, since it is a riskier job.
