I just purchased a room to room fan. So far its helping heat the rest of the house.
The fan I bought is here:

It fit snug in between 2 studs in the wall, I purchased a dimmer switch that controls the setting, the fan itself says on HI, and I use the dimmer switch on the wall to control the speed.
As for the setting on my stove itself, I guess its still a work in progress. I've been trying to use it on "stove temp", i keep the fan towards Low, and the feeder on 3. Its been in the 20's outside and my house has been been about 74 all day, the other side of the house about 66. The only thing is ive been going through more pellets than I thought I would be. I thought a bag would last me a full day, it seems that a bag is only lasting me about 12-16 hrs, so its like a bag and half a day.
The more I keep trying things the more I figure out, but for anyone who's reading this who is interested in buying a XXV....I HIGHLY recommend it.
