Was trying to figure out age of a Seisco Electric Water heater. Found another website that says the first 2 numbers are the year of manufacture but that is obviously not the case - 1954 by that method.
The seller was pretty sure the unit was installed in 2004 when they did a major remodel so I can live with that unless someone has a better guess.
The thing that gets me is that, according to Seisco website, this model - RA-28 - runs at 28kw. That’s a lot of power. I=P/E tells me this thing can suck over 110 amps. It was hooked to a 100 amp breaker (200 amp panel) and it’s been that way since 2004. They had to replace the heating element about 4 years ago. Also a household of of a dozen people, kids & adults. Wouldn’t want that electric bill.
Any comments about age or size of breaker would be appreciated.
