Just to bring up to date, the wettest spring, crappiest summer ,most odd fall, now the coldest in 50 plus years, minus 16 c tonight, minus 30 c  Thursday , then colder at the weekend ....septic frozen , water frozen, power going on and off like disco lights. The composting toilet is solid.. so have to use a bucket , put peat moss and ceder chips in the sprinkle thawed out water on it , shove it outside where the critters can get to it, it freezes into a block, will deal with it in the spring... Thank god for the gas stove and candles and my Russian -40 sleeping bag. Don't know how the settlers did it, no choice and lots of balls I guess. Bring on the recreational smoke, then I can dream  my way to spring..

So I bought a wreck of a house for very little money, after promising myself I  would never do this again. It was remote and so cheap.. sucker.!!! There is no heat, but there is five acres of wood. I have working hydro to the property, water by the bucket and composting toilet.
I need heat and want to build a Batch Box, been following RMH  ( forums youtube etc ) for couple of years and feel confident in my ability to build one. My problem is the best position for the heater is a floor area of about 7ft x 6ft, so I started to look at Dragon style heaters, then one night about a week ago while mooching on youtube I came across a guy that had built a BBRMH on a small foot print, and the heat conduit instead of metal was made up of using concrete blocks  using just one of the cavities,, the other was blocked off and filled I think, he angle cut the block for the corners and cut holes in them to go up a level, ending in a vent to a chimney...nice idea I thought, so like a fool I didnt book mark it and a week later cant find it anywhere.  I would like to do the same and make it into a tower about 8ft high covering the block with cob  as a finish. Does any body recognise the build I described and do you think such a structure could work? I would love some advice
