A wood stove or pellet stove can be a good option to heat a Quonset hut home, with a few caveats:
First, a pellet stove is much, much easier to vent than a wood stove. Pellet stoves are extremely efficient and part of their efficiency is that they are extremely clean burning. Many, if not most, pellet stoves can be vented straight through an exterior wall with just a vent cap on the outside of the wall, with no requirement for a full-on chimney like a wood stove would have.
Second, with either a traditional wood stove or a pellet stove, you will want to position it on an end wall. Placing a traditional wood stove or pellet stove somewhere along one of the sides of your Quonset hut will create problems for venting it. Think about it this way: when it rains, all that water is pouring down the sides of your hut. If you are trying to penetrate the side of the hut for a flue or chimney, you are basically putting that hole right along a waterfall. The end walls are a far better location.
Third, a wood stove chimney, if it is to pass through the Quonset arch, will require a hole about 10 1/2" in diameter. This may be a larger hole than your Quonset hut manufacturer will allow without voiding your warranty. If you plan to install a wood stove, I would strongly urge you to make it clear to your salesperson at the beginning of your discussion of the building with them. It might be possible for them to accommodate it in your building kit, but there could be issues, especially with larger buildings. Or they may need to adjust the gauge of your building (or make one or two arches heavier than the rest) to compensate for the hole. Cutting holes in the building is a big deal and is definitely something to be take seriously.
If you do end up penetrating the arch for a wood stove chimney, you will be much better off doing so at the very dead center of the arch, rather than to one side or the other. The reason, again, has to do with water intrusion. At the top center of the building, virtually all the rain water is going to be flowing down the sides and away from the chimney flue. This gives you a much better chance of keeping water out.
