I'd think about using a hybrid hydronic/hot air system. http://en.wikipedia.org/wiki/Hydronics
Setup a hot water heating system "in a box", well outside the yurt. This could be as simple as an insulated cookpot with a low flame underneath, but probably better would be a small propane water heater since it has an integrated thermostat. To get more efficiency, put a thick insulating blanket around it. The radiant heater (could be a scrap automotive radiator) is in its own duct nearby, and the other side of that duct is connected to your space. The pump could be an automotive coolant pump. Using a water heater, you might want to make sure the tank is vented to avoid expansion problems. You blow air through the duct, which is attached to the yurt somewhere near the base with flexible, insulated ducting to heat the space. To avoid noise, perhaps situate the fan inside the duct right in front of the radiator, or just use the fan that came with it :) This avoids any trouble with CO or CO2 if the source air is ducted from somewhere above and away from the heater. -- You received this message because you are subscribed to the Google Groups "hexayurt" group.
