I don't know where the author got the information that water heater blankets are a good idea. Modern water heaters (post early 1990's) have high performance foam insulation which performs much better than any thin blanket of fiber glass could every hope to be. Consequently, adding a water heater blanket is a great deal only for the manufacturers of these blankets.

I have no idea how the author got the impression that these blankets could be paid off in less than a year. There is no basis in fact or data to substantiate that claim for modern water heaters.
