Have you considered using a spiral of pipes either filled with water and propylene glycol, or oil and have it passover the heat of your stove? This way, the fluid moves with the pressure of the heat toward the cold, where the main spiral center is, and you have radiating heat rising to the surface heating the inside of your home. some people in yurts use a bed build over the actual stove which is casted in a mound of dirt hardened into some sort of concrete. I also have my own "hard-top" tent for the cold winters here, and greatly enjoy the cool night sleep. I simply LOVe fresh air! Thanks for your reply, stay warm, keep your smile, thrive on and namaste :)
