Seems to be lots of disadvantages using a stove like this.  Heating multiple units.  Looks like the unit blows some hot air.

A forced air unit has several disadvantages, the more passes to capture heat the harder it is to clean for starters.

Air doesn't cool or collect heat as well as water, it's easier to heat simply because it doesn't hold as much heat. Warpage would always be a concern. Even Harley Davidson has gone to liquid cooled engines after over a century of air cooled engines. If after a hundred years they gave up on air.....

I've built several air stoves and have modified a few as well, everyone of them if you had a hot enough fire to get the required amount of heat, you stood a very real risk of a serious burn if you laid your hand on the stack.

I was thinking about the warpage issue as well. I thought it was pretty neat they made one for outside but to me Id much rather have a plan jane woodstove in the basement as I do now. Then you catch all the heat that stove produces. These are fairly new so Im really anxious to read some reviews about them.

Not that new, outdoor forced air furnaces have been around for awhile. Usually most people like the advantages of the other stuff you can do with an abundant supply of hot water, heat your pool, heat your sidewalk, heat your hotwater, heat multiple buildings, etc. I suppose a person could lay a bunch of itty bitty ducts in your sidewalk then pour the cement over them if you wanted a forced air sidewalk heater

I've seen some around. It seems they have to be terribly close to a building. I know one man who had his house burn down from the furnace being too close. I think a huge duct sticking through your wall would be a pain. How do you mow between the furnace and the building with a huge tube between. Also, it can't be  buried so heat loss could be an issue.

The only advantage I see from reading the site is extreme heat being delivered to the home.  Around 220 Degree air would warm a house up pretty fast.  The firebox from the photos seems pretty small, maybe another advantage would be considerable less wood usage during the winter.  Looking at the photos, the stove is scary close to the house, and ... after much thought heck no! Janky Setup from the pics...

Your are right no way to make a clean looking hookup. Plus way to close to the house.

The installs don't have to be so hooky as the ones the Web typically shows.

 Our plan is to have ducting poured into the foundation. Either a square notch or actual round ducting connections poured directly into the concrete. Either way should look presentable.

I think you might be mis informed about Harley engines..The V-rod is the only bike that is liquid cooled in the Harley lineup

[MattyNH]

 I would like to hear from someone on this that actually owns and runs a air furnace..Seems to be a lot of speculation since no one on this post owns one....Some say on here they are close to the building..Its no different than wood boilers..I know where there is a wood boiler.. Its so close..They could open a window and fill the boiler

[Rscott]

I am building  one, it's all just steel right now. But have tended to one for a friend while he's out of town.

 Works great. Set the thermostat in the house and it's all good. His has a smaller firebox so needs filled 3 times a day,  but works just fine.

Ayuh,....    The drawback is, Air is a terribly inefficient way to move heat,....

I hope so.

But, growing up I used to run Hare Scrambles and Enduros, got quite used to pulling the jug and throwing a fresh set of rings in about once a month or so on the air cooled motors, got my first water cooled dirt bike and ran almost two years with out even a set of rings, let alone a complete rebuild. Betcha once the water cooled v rods have been around for awhile and improved engine life is noticed and desired, the rest of the lineup will follow with water cooling. Even Duetz has seriously cut back on the engines it still offers as air cooled, don't even get into an oil cooled engine, have one, it sucks.

Nice Avitar and phrase at the bottom of your post there Bondo, You have got to be from Maine, or at least you should be, that is 3 things near and dear to my heart. Moxie, Bondo and Grease!
