How old is my water heater, furnace or appliance?
Type the brand and serial number from the label and we’ll check it for you against our database of 109 brands.
How it works
The serial number gives the date the unit was made, not the day it was installed. Most are installed soon after, but a unit can sit in a warehouse first. If you have the install paperwork, that date wins.
Some brands reuse their date codes. Bradford White’s letters start again every 20 years, for example. When a serial could mean more than one year, we show every year it could be. The unit’s condition, or a date printed elsewhere on the label, usually settles it.
We read only the formats we could check against the maker’s own guide, or against at least two independent guides that agree. If we can’t read a serial, we say so rather than guess. Each brand page lists its sources, and we keep a list of the brands we can’t read yet, and why.
