Hey Guys,

This was filmed a few weeks ago when we had a stretch of -15 to -30 degree weather and this video shows how my Pole barn / Post Frame metal building did during that stretch. I say it multiple times in video but I am running ZERO under slab insulation , so you can see that a well planned system can heat in extreme cold temperatures. You are not throwing money away heating the earth , contrary to what is taught or gossiped about. You need closer spacer ( 8" instead of 12" ) which means more tubes , but the cost isn't that much more vs pink foam insulation costs. Thanks for watching and I hope these videos help with your building project!
