He built a large rmh in Ireland that is truly a work of art, well documented here on permies

Rich, y'all are certainly big hearted permaculturists, if I was 40 years younger I would jump in my old truck for a visit or an internship.  You have a lovely spot in the Great North Woods

Best of luck to ya, this is a generous and amazing offer to help others.

I feel your pain when it comes to  the crawlspace issue. Our 105 year old house was free when we bought this land, as it had so many signs of age and neglect,repairs 90 % complete,  and the hardest were those involving spelunking.   With some ingenuity, you can still make this possible. Last year I helped a buddy cut through his wooden floor to install steel reinforced support, then rebuild the space, then build a jtube and bench design.  He never had to crawl

Others here are experts, not me, I would just say please research and find one rmh that works for you in the wilds of Ontario.  I am most impressed with Uncle Mud designs and building that specifically helps any homeowner-builders , tailoring to the site and climate.  Check his work.  

Do not despair, even the humble j tube
can be used for cooking and warming.  On the upscale side, please peruse the stoves of Matt Walker, two amazing folks here have documented builds with his designs, Burra Mallaca and Tony ullje.  Read those threads for effectiveness and aesthetics built into the project. If memory serves many of his are batch box style, better for Ontario winters.  
Predicting great success for your project!

In brief,
they rock and deserve 10 of 10 chestnuts.  Using them for 12 years straight, super selections, altruistic folks, great value for dollars spent.  Respect.  

Mick, it might take a bit to read  through the discussion, but please refer to a thread entitled " are you interested in building a rocket mass heater?"

Some folks have no problems with home  insurance, if they live in certain rural areas of the USA.  
However, many wood burning families are playing it safe with getting full permission from home insurers , that is my real life concern.  You should research your specific zip code and what wood burning regulations apply. Good luck

My grandfather had an old Ashley in his basement, and a newer one upstairs.  They are simple but also ingenious,  I had a homemade replica for 8 years and loved it.  But I can see the wisdom dispensed here by two experienced men
Perhaps putting your energy into insulating could achieve the same warmth overall.

That calendar often lies, you are still a young man with the energy of a teenager!
Just as Saint Francis made a home for a ravenous wolf in the town of Gabbio, you have given a lonely stray a happy home.   Good cat karma, my friend.  

This is probably more work up front to save you time in the long run...
Could you reposition the array for easy access?  You mentioned it is a  small size

Your time has been well spent Luka, you have a gorgeous abode.  Respect!

Croatia is such a fabulous country with a vibrant culture. I had a long summer on the islands around Korçula decades ago, and the beauty is still etched in my mind, the inland areas are also amazing

I want to dovetail with comments from Cristobal
Camping has been in my blood since the age of diapers and sippy cups.  But living a couple of years in an RV was not for me, even as a college hippy. They are predominantly made of rubber and plastic,many are magnets for mice and mold.  Please make that your last choice.  I spent a year in a simple greenhouse that, with good ventilation and shade cloth, was far superior for my health and my wallet.  Although I did wake up once to a curious rattlesnake nearby...

Best of luck to you, the islands of Greece are quite magical with stellar kayaking opportunities
