Can anyone tell me a low cost way to check my boiler lines for heat loss? I want to see if I can improve my situation. My setup is an owb 150ft from house and ten feet from the shop. I have two 1" lines in and 2 1" lines out of the house. Same with the shop. All insulated with 6 around closed cell foam. My brother in law has the same owb and just ran one 1" line in and out to his house, also he just bubble rapped his lines and put it in tile. The snow melts all along the ground where his lines are, mine do not. We cut wood together and usually I het more than he does. He burns probably a third of what of what I do. I can't figure it out. He keeps his temp in his house between 75 and 80, me 62 and 65. I am wondering if my second line in and out is holding me back?
