How old is my STATE tankless water heater?

1. Find the rating label: On the unit's rating plate label; State's pages do not say exactly where on the cabinet it sits.
2. Take a photo of the whole label, or note the model and serial numbers.
3. Check it on Appliance Age. It is free, and no account is needed.

On the unit's rating plate label; State's pages do not say exactly where on the cabinet it sits.

Keep the model, serial and any separate production code or printed date together. Not every serial number contains a publicly decodable 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.

Tankless Water Heaters typically last 15 to 20 years. Use, water quality and maintenance matter more than the brand. Descale (flush) it once a year, more often with hard water.

Parts that wear out most often on tankless water heaters:

• Inlet water filter
• Flame sensor
• Igniter
• Flow sensor

Have the model number from the rating label ready so the parts fit.

Every STATE check is compared with Health Canada, U.S. CPSC and U.S. NHTSA recall notices.
