If you want to be free of the need of a power vent, do yourself a favor and build a chimney....2 flues to be safe. It will be short money in the long run. The Hitzer will be VERY happy, as will you!
There is the "how reliable is the power grid" where you are going....need for a generator? Well pump, septic pumping system....lighting, refrigeration..................
If you can make it simple, I'd opt for that. If you need to live 'on the grid', perhaps you better consider the other requirements.....for a "Non Mountain Man" life.
my .02.....life isn't that simple, no matter how much we second guess it!
