It's important homeowners know how to take care of your water heater to maximize your water heater lifespan. Just because you don’t see your water heater on a daily basis, doesn’t mean it should be out of sight and out of mind. They require attention and maintenance to stand the test of time. Speaking of time — exactly how long do water heaters last?
Water heaters last 10 years on average. While their exact lifespan depends on the quality of your care, none last forever. They wear down as they age and inevitably will break over time. Regular maintenance, however, can extend your water heaters lifespan up to several years before a replacement is necessary.
How Old Is My Water Heater?
If you can’t remember how old your water heater is, the manufacturer’s sticker (which is usually placed towards the top of the tank) will tell you. This sticker contains the serial number, which is a 10-digit string of letters and numbers. However, all you need is the first 3 characters to clue you in to the age of your water heater.
An example of a serial number would be, “C180493278.” The placement of the letter in the alphabet indicates the month of its manufacturing. C is the third letter in the alphabet, representing the third month of the year, which is March. The following two numbers indicate the year it was manufactured. In this case “18” would stand for 2018. Therefore, March 2018 would be the age of a water heater with this serial number.
DIY Water Heater Maintenance Tips
If you are comfortable working on your water heater without the help of a trained professional, there are a few things you can routinely do to maximize its lifespan.
- Check the water’s temperature.It should not be set much higher than 150°F. Water that is too hot could have a damaging impact on the rest of the system.
- Check the pressure relief valve.Lift and lower the lever every now and again. If water begins draining, wait until the water has fully stopped before closing the valve again.
- Insulate hot water pipes.Foam insulation sleeves keep the heat from escaping, so all of the warmth and energy will be conserved to keep the water hot. If your showers are never quite warm enough, this will make them more comfortable. It can also lower your utility bills.
However, if your water heater is leaking and you think it may be a danger to you or your family, keep your distance and call a professional immediately.
