Help finding the model and serial number

Where is the serial number on a GIANT tankless water heater?

On the unit's rating plate label; check the product manual for its exact position.

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 GIANT tankless water heater last?

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.
