I’m trying to date the age of the vacant ranch dwelling I inspected this morning. The dwelling had the functioning, ancient water heater in the photo. It appears as if it is original. Now before anyone goes nuts, I know it should be replaced…just trying to get the age of the dwelling.
Here are the vitals: Rheem ‘Standard Rheemglas’ 52 gal.
Model # 665H-52D
Serial # 1237 3759

That unit is way too old to be a 2003. Rheem does not make the water heaters with a single panel cover plate any more (at least not that I am aware of) I found the same the same thing you did on Rheems site - hence the number listed above to call Tech support. It looks like it should be somewhere in the mid to late 70’s. Let us know.
All my research on Rheem indicates that they used a month-month-year-year system with any remaining digits being consecutive annual numbers. That would make it a December 1937 unit. That would also make it the oldest water heater I’ve ever seen. My previous record was a June 1943 unit, also by Rheem by the way. However, it had been “remanufactured” several times; perhaps your unit had been also.
I talked to the Rheem tech line and they indicated a water heater with an 8 digit serial # is at least 30 years old. The tech on the phone tried to use the mmyy formula, but we both agreed there is no way the unit was made 12 of '37.
Apparently 8 digit serial #'s do not use the mmyy formula.
Based on this ‘goose chase’ I’m tagging the home at between 30 and 40 years old…
Well I got an old one just like it yesterday, home was built in the 60’s and 66 is in both the serial number and the model number…looks exactly like the one in your picture. The well pump actually had a pulley on it!
Hello everyone! I know this post is an OLD post, but thought I’d share a little more to this for your knowledge. I just spoke to the manufacturer about a water heater Serial # 168 7333, Model Number 665H-52D. They don’t even have a listing for this unit. It predates their records! But, she believes the first 3 to 4 digits is the month and age. For mine it would have been made in January of 1968. Which does make sense and goes along with the age of the home I am inspecting, which was built in 1968. BTW… This unit was still in use and working!!
Just trying to figure out the age of a heater we are replacing. Looks like the ones pictured here. We figured out it is Jan 69, the year this home was built. Just replacing it for something more efficient that hopefully won’t die at an inconvenient time. But this one still works,
