Heater Age??

Hello Everyone. I came across a heater for the second time today and could not identify the age. It was a conventional furnace probably 15-20yrs. The manufacturer Patco(Magic Chef on inside cabinet) Serial # A23058CAB. Any help with this would be greatly appreciated.


What is the model # ??

I did not get that, I thought the serial# is always used.??

You can always call the manufacturer if it’s not covered by any SN -> Age guides posted on this board, or book refereces like Prestons & CD.


March 1980.

Thanks Russel… I thought it was around 20yrs or so, but was not positive!
