John Wood & AO Smith Water Heater Guide: Understanding Your Tank and Warranty

Learn essential information about your residential John Wood water heater, a common brand owned by AO Smith that has been a leader in the industry for over 50 years. John Wood offers a full range of products, including gas, tankless, and electric water tanks.

Key Identification & Technical Details:

• Locate the Rating Plate: The large rectangular sticker contains vital specifications, including the brand, model number, serial number, capacity, and voltage. It is usually located on the side of the tank, but sometimes near the top center or bottom foot.
• Identify Your Model Type: Look at the model number prefix—Electric models commonly start with E, G, or X, while Gas models start with G, H, or P.
• Determine Tank Age: For John Wood/AO Smith tanks, the manufacturing date is found in the first four digits of the serial number. The first two digits specify the year (e.g., 18 for 2018), and the next two indicate the week of that year (e.g., 37 for the 37th week).

Warranty Information:

• Residential John Wood tanks typically carry a 6, 8, or 10-year warranty.
• Warranty details can be found on the rating plate or the product manual. Additionally, the dedicated John Wood/AO Smith website allows homeowners to check their remaining warranty period by entering the serial number.
