How can I tell the age of a Thermalux tankless water heater from the serial number?
Monday, April 19, 2021
The Thermalux serial number is 12 digits, and the first four digits are the year of manufacture, followed by a period. The next 2 digits are the month, followed by a dash and the last 6 digits. So the serial number 2020.10-043012 means the unit was manufactured in October, 2020.
To determine the age of another manufacturer/brand of water heater, go to How do I determine the age of my water heater? Also, see our blog posts How can I determine the age of a water heater if the serial number is missing or decoding it is impossible? and What are the most common installation mistakes with water heater replacement? and Are water heaters required to be raised off the floor? and What's that powdery crust on the pipe connections at the water heater?
