I have just built a shop 32 x 48 well insulated with 7 - 1/2" pex floor zones. It is 150' from my house. (Approx 2500sq') today I just buried the thermopex 1" line from building to building. I plan to add a piece on the side of the shop next week to house my new gasification boiler which i have yet to buy. I was planning on a new horizon bio mass combo 60 with 1000 gal storage which also I don't have. Is the 60 a good unit?? I do have a 1000 gal. Gas tank that was designed for underground. It is thick. Can this be used for storage? I hope to learn from this site and post progress for others like me to learn. Hopefully I get a few hits.
