How can I tell the age of a State Industries water heater from the serial number?
Thursday, September 13, 2018
The first two numbers of the serial number of a State water heater are the year of manufacture. Newer State water heaters, like the one shown below from 2013 also list the “BUILD DATE” below the serial number so there’s no interpretation necessary; but, for older ones, you will have to depend on the serial number.
State Industries has also manufactured water heaters under multiple other brand names over the years. Many have been discontinued for years, but a few older water heaters with these nameplates may still be around. If you look carefully at the bottom of the data plate, you will see the name of the actual manufacturer in fine print. This is important to look for, because some retailers have switched manufacturers over the years. Here’s some of them, and they all use the same State serial number code shown above:
• Ace water heaters
• Ambassador water heaters
• Barnett water heaters
• Century water heaters
• Crosley water heaters
• Energy Stretcher water heaters
• Freedom water heaters
• Hardware House water heaters
• Kenmore (Sears) water heaters
• Master Plumber water heaters
• Mission water heaters
• Nationaline water heaters
• Patriot water heaters
• Penfield water heaters
• President water heaters
• Regency water heaters
• Reliance water heaters
• The Plumbery water heaters
• Thermo-King water heaters
• TopLine water heaters
