I see Home Depot has a line of GE/Rheem gas water heaters:

* 40 gallon, 6 year warranty, $488
* 38 gallon, 9 year warranty, self-cleaning, $498
* 40 gallon, 12 year warranty, self-cleaning, $578

Other specs seem the same.

My question is, what does this self-cleaning mean, and is it likely
that the extra bucks for the 12-year is a good investment?



(given that I'll also be paying to have them install it, which given
venting and access issues will at least double the cost, the extra $80
isn't a big deal, but I'm still curious about it)

Thanks.

The self cleaning units, if I remember correctly, have a cold
water supply tube that goes all the way to the bottom of the
tank and is curved in such a way that it swirls the water
around which keeps the sediment stirred up so it goes out with
the hot water.
