Use either a Gravity hopper feed or a standard screw type auger. The hollow flight auger used in the AA boilers is noisy, would drive you nuts in an otherwise quiet setting.
The specifics of the boiler controls I'm not well versed on. You could use one of the fancy outdoor temp anticipator setback water temp control aquastats, but the savings I think would be minimal. Neat feature though.
I really like the ideas that Richard posted, pretty much covers it all. Radiant floor heat is a real luxury, and separate ducting for A/C, that's the way to do it. Too bad you want to locate next to an airfield and have a hangar for your planes
.. The wind generator idea and a 100% effecient electric boiler is appealing.. but would probably be too much of an obstical at and airfield.
If you build the house RIGHT with lots of insulation, and excellent windows, your BTU needs won't be that high. Especially with hot water heated 'hard floors'. Would you heat the hangar floor too??
Lots of neat ideas for building a good hangar or shop available. What a project...
Take care, Greg
