FOR ME I bought a 50 gallon tank since it was the largest that would
fit, with a high output burner to minimize running out of hot water,
the warranty is on high output tanks is 7 years. could of got a 12
year tank but I prefered more hot water over longer warranty which is
generally pro rated anyway and replacement usually based on list price
rather than sale price.


sometimes a tank on sale is cheaper than the same tank warranty
replaced.

minor $$$ savings are just that minor, like some fret buying a new
tank, to me its a low enough cost, like one candy bar a week who
cares,

bottom line i just want lots of nice hot water. costs are way below in
priority
