Hi Matt; I can't tell you about workshops in NB, but thought i would respond anyway. Do you have a copy of ianto evans book rocket mass heaters ? It is available online as a book or download as a pdf file. It will answer most of your questions about building. I have built one very successful rmh so far and I am planning to build my second this summer in my garage/shop. The current stove out there is a double barrel stuck over by the wall. shop is 24x32 and your only warm near the stove .My plan is to run the mass length wise between the two bays. Encase the whole thing with regular red brick giving me a warm spot to place parts and tools as well as warming any vehicles parked next to it. As i did in my greenhouse, once your pipe rise's up vertically out of your mass you can make it go anyplace it needs to reach the roof outlet. The pipe at that point will be low temp and can be placed as close to things (wood) as need be. I am toying with the idea of placing a hydrolic oil tank in my mass that i would fill with used oil, that could just be a part of my mass OR... I may try pumping it thru pex tubing to warm a small portion of a cement slab. Just some thoughts for you. Good luck with your build. Tom
