Thanks a bunch for the follow up, we have them in our area, even with the snow if they are stretched and heated they last a couple of years or so.
I would look into axillary heating utilizing the Methods of Jean Pain. Look up bio heating and bio fuel Jean Pain Method. Search also for Jean Pain method Siberia and Northern Canada, Alaska.
Personally I believe for my area the Jean Pain heating method will work if you cover the mass with either sawdust or
straw from straw bales or straw bricks. My plan is to do that, then cover it with a
pond liner or the rubber that flat roofers use. I just found out about the flat roofers, who use 20' wide by 100' rolls. The rubber is folded over at the 10' mark so you need to roll out to the length then open it up to the 20'. Throw some logs or tires over this and voila, a very good hot house insulated from the cold. When it snows, the snow will add another layer of insulation as well. With the Siberian experiment, they did not even do the full Jean Pain method and had a constant 90+ degs Fahrenheit in winter, in Siberia.
When I get to doing this, I want to do 2 mounds, one with the pipes that carry
water, the other with vent pipes, see what happens and how long each of them last to
boot. Well hoping that this will happen this next summer actually.
Cheers and best of luck to you.
