I was considering a us stove 8500 at first but I havent heard to many good things. I have a 3500 square foot home not including the basement. If the pf120 is everything they say it is I think it will be a great supplemental heating source. What are thoughts on this? The other option I was considering was an outdoor stove but this pellet furnace seems more practical. I need all the help I can get.

I am interested in a pellet furnace as well. Dang $6000 is a lot of money though. Of course your house is twice as big as mine and therefore probably twice as expensive to heat so makes more sense for you probably.
I would not install an outdoor boiler.
You need to share a little more information. What is your current heating system (i.e. do you have forced air or forced water and what fuel do you heat with)?

PF120 is a good unit, for forced-air systems. If you have hot water baseboard heating you want a PB120. Expect to deal with 6 to 10 tons of pellets per heating season, and that these pellet furnaces will require some attending-to every few days (ash cleaning, pellet loading), unlike a set-and-forget conventional home heating system.
To my knowledge, Harman does not manufacturer a PB120 boiler, the boilers they manufacture are the PB105 or a HydroFlex 60.
I have forced air with a unit in the basement and another unit in the attic. That was my next question as to how much pellets these beasts go through? I don't mind tending to it every day or couple days, I am just looking at the most cost effective way to supplement heat. We have a prefab fireplace and I hate the thing, but I figured rather than rip that out and install an insert I would spend couple more grand and get something that could heat more?
Last year,(365 days) I burned 8.5 ton for heat and DHW heating 2200 sq. ft., no fuel oil used. I clean my boiler weekly.My heating costs are about 1/2 what I was paying for fuel oil which averaged 1000 gals per year,didn't take but a few years to pay for the pellet boiler.
How much fuel do you burn now for heating? If you know that you can convert that fuel use to pellets.
Do you have oil, propane or natural gas? I'm guessing propane or NG if you have a unit in your attic.
I don't know enough about your climate, your heat pumps or your electric rate to tell you for sure. But my guess is that a pellet furnace won't save you much money (if any) and probably not nearly enough to generate any kind of reasonable "payback".
