Hey dave, the pics are not possible as he is a former employer of mine- he just recently quit from the place we work-wish I could though because it might give you some ideas. Sorry. I saw his setup when he took me and a few other guys to help him move some firewood he was selling.
He built a seperate building around the boiler with the boiler being in the middle -nothing fancy, 2x6 constuction, gravel floor. But I suppose you could build it to suit you're own specs. or desires. He just uses it to heat a approx. 1900sft house and hot water. The shed itself was divided into three sections across its width, with the smallest being the one around the boiler (in the middle). I think the reason it caught my eye was that I have never seen anyone conceal what some may consider a minor eyesore in its own self contained structure. It just stuck me as a good idea, because along with protection for you're boiler you have also built in an area to bring you're wood under cover -not to mention any other extra space you could end up with if you enlarge its design. In essence, it is just a nice shed dedicated to housing the boiler and its fuel. You can't really go wrong if you build it with you're needs in mind.
I have also talked to satisfied owners of indoor boilers and have concluded that when deciding between indoor and outdoor it comes down to circumstance. It is mostly dependent on how much and what kind of wood you want to cut, size of area to be heated, desired burn times and as you mentioned, imposed stipulations by you're insurance co. The list could go on.
I heat a 2000sft cape style with a indoor hot air wood furnace, full time. My only complaint is that it doesn't heat the hot water too. I'm looking into a outdoor boiler because I want to heat the house, portion of a 4000sft barn, small outbuilding, and later some greenhouses. Oh yeah, the hot water also. So the OWB's size to me would be important.
I hope this helps. Keep the questions coming.
