How Old is My Water Heater?

If you're wondering how old your water heater is, there are a few ways to find out. First, check the manufacturer's sticker on the unit. You might see a manufacture date. If that's not available, look for the serial number on the unit. Compare the letters and numbers in the serial number with the manufacturer key to find out when it was made.
