In my case, it was not pro-rated. I was given a new gas HWH by Sears to
replace the one that developed the small leak within the 7-year tank rust
out warranty period. I did need to bring them the old tank though, which
was not an issue.

having only 1 heater leak before the warranty ran out, and as far as i
know its still a pro rata warranty....

number of installed months, vs number of warranteed months, gives a
percentage, thats then applied to a brand new similiar heater at full
list price

on that one heater the sale price was less than the pro rata price,
kinda mad i bought my new one somewhere else........

warrantys are sales tools, they rarely help the purchaser much. wheres
your original invoice? company like sears might no longer be in
business in 8 years.........

just look at all the retailers who have goine out of business over the
years.....

a warranty from builders square or hechinger isnt worth the paper its
written on........

the BTU # is from the manufacturer, they vary from under 30,000 BTU to
75,000 BTU on my current tank.

higher btus cost more to build, better stronger burner and heavier
tank to take the added heat.
