How old is my Rinnai boiler?
Check the rating label of your Rinnai boiler for the serial number and any printed manufacture date. Enter the details or a label photo to check supported date formats, typical service life and available recall notices.
Check your Rinnai boiler
- Find the rating label: On the unit's rating plate; Rinnai's North American pages checked do not describe its position, so check the installation manual.
- Take a photo of the whole label, or note the model and serial numbers.
- Check it on Appliance Age. It is free, and no account is needed.
Where is the serial number on a Rinnai boiler?
On the unit's rating plate; Rinnai's North American pages checked do not describe its position, so check the installation manual.
Keep the model, serial and any separate production code or printed date together. Not every serial number contains a publicly decodable date.
Checking the manufacture date
Use the format that belongs to this product family. A printed production date, a supported serial code or manufacturer confirmation can establish the age. Repeating year codes may leave more than one possible year; a model-series introduction date helps narrow the range but does not date your individual unit.
How long does a Rinnai boiler last?
Boilers typically last 15 to 30 years. Use, water quality and maintenance matter more than the brand. Have it serviced yearly and watch the pressure gauge; frequent topping up points to a leak.
