Question about outdoor wood burners

[dragonfly1113]

I am thinking about buying an outdoor wood burner. I need information from people who have them, either outdoor or in a building.
I have checked with a local company who has one brand and the cost for it was $6000 but when I asked what price installed I was told $5000 extra to install it and for a water pump because that unit didnt come with a pump. It was an outdoor one. Brand name is a Crown Royal. I called another place that has one called a Hardy but have not heard back from the guy on pricing and such. My husband says he saw a outdoor wood burner that has to be put inside a building and he said it was cheap at tractor supply.
I have a building outside that I could put one in and store my wood in. I need to know what the difference is between in a building and outside.... is the only difference is that one would rust and the other would not?
Anyone who has one of these woodburners please let me know about how much is a good price to pay for the unit and it being put in. And what the difference is between the two.

DH is starting to manufacture outdoor woodfurnaces. His will hook up to your existing duct work on your furnace. Its in its own building. If you do not have duct work you can run it through a wall or up under your house through a floor vent.

The fan will run either off electricity or you can plug it into an inverter and run it off of solar or wind via your batteries (this is how we ran ours. Free heat)

The boiler type that you write about with the high installation charge is you have to run water pipe through your house if you don't already have radiant heat. Also add $1500 for anti freeze to keep it from freezing up if you are not around to burn wood in it and go back onto your old furnace.

Oh man make sure you have a complete installed price with the correct components!! We put an Empyre 450 into two buildings using three pumps and four fan/coil units either into existing furnaces or as a seperate air handler. Total cost? We did the labout and excavating and it still cost 21k My brothers Empyre 250 to a single fan coil cost 12k we did all the labour. ensure the installer is using an insulated water proof underground pipe bedded in sand. We went lower than frost level despite assurances it would work 18 inches under the surface. I'm a licensed heating contractor and I just couldn't reconsile that idea with known heat loss out of an insulated pipe only rated to R5! They could be right but if you bury it down an extra 2 feet you won't be wrong either! Ask for references I've had to go in and correct several outdoor boiler installs that were set up so slip shod there wasn't any hope of getting heat out of the water efficiently!
