How old is my Ruud water heater?

1. Find the rating label: On a label on the front of the tank (based on guidance from parent company Rheem).

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.

Water Heaters typically last 8 to 12 years. Use, water quality and maintenance matter more than the brand. Drain a few litres from the bottom yearly and check the anode rod every few years to slow corrosion.

73 Ruud models are currently ENERGY STAR certified, 28 of them sold in Canada. The certified models went on the market between 2020 and 2026. An older Ruud water heater may use more energy than today's certified models.
