i have seen them used in high effeciency furnaces where the heat exchanger is extra convoluted and wont draft properly by gravity.
i don't think i have seen any that were add ons.

In my case the power vent was added on to a tankless heater because the original hot water heater had been put in a crawlspace and the condo built around it. When the original hot water heater failed, it could not be removed thru the crawl space access hole and a new one would not fit down the access hole. Hence I went with a tankless, mounted above the washing machine in a closet but since the original vent was on the other side of the house, the new water heater had to be power vented out the sidewall of the house.
