I'm in the process of planning out my install of an AA 130, and after reading some threads here, I've opted against a garage installation.
So that got me thinking of alternatives. Opinions and suggestions are welcome...
First option: build small boiler-room structure detached from the house (see pic) out of concrete and cement blocks. Specs in the drawing are not going to be as precise as they are in the drawing.
Second option: dig pit next to house, pour pad, build block walls, or use pre-fab'd concrete box
- Ignoring local codes for now, how high does the chimney (or stovepipe) need to terminate above the shed's roofline? Is it relevant to the house being about 10 feet away?
- Should I pour an additional pad on top of plastic sheeting to elevate the boiler just an inch or two from any ground moisture that may wick up through the floor?
Is underground completely insane? An underground coal bin would be much easier to fill with my trailer, and I have a backhoe that can dig the hole and lower in the boiler no problem. Making it structurally safe is another question. It would need to support a vehicle, and not weaken the soil support of the house foundation. If I could solve those issues, underground is very appealing to me.
I'm not a builder, so I was going to pay/trade someone do the masonry work. I still haven't figured out how to cover the structures, either. Wood and shingles? Not sure how to cover it and still be able to fill the coal bin with a dump trailer.
