I think I need to replace my water heater [getting it checked next week], and
looking at them on the internet, I can't find any to compare with what I have.
I think my 40 gal. Rheem has a glass tank(?), the builder's specs are hard to
read. Is that right? If so, why don't the web sites indicate what type of
tanks they have? I finally found an A.O. Smith site, which mentions a glass
on one of their lines, is that what I am looking for, if I have been
happy with the water heater I have had for 18+ yrs.? Is it not usually listed,
because all, or most of them ARE glass coated?
It also mentions the different types of venting, which is something else, I
don't know about. My water heater is down stairs, next to my heater, in a big
open unfinished storage room. [It's a split level house. One occupant.] Is
there anything special I should know about that, so I won't be sold something I
don't need. TIA, for anyone who will reduce my ignorance about *today's*
heaters, and what I should be looking for or buying. :)
