I ask because most HWH's come with an "annual cost" sticker on them that provides an "average" use cost and almost all of them are in the $230-270 a year range. Which makes saving $300 a year seem a bit odd.

Here's the explanation: My sticker (and maybe yours) is based on a propane cost of 77 cents per gallon. Propane here costs about $2.40 per gallon.
If your sticker is based on that price, the tank water heater annual cost would be $779 instead of $250 when using the current propane cost.
My sticker says that it uses 189 gallons of propane per year ("$145"). Scale that to the real cost of propane and it is $451/year.
