New guy here, I did do a search found nothing on the subject. Have had 3 owb with alot of piping problems and yes for the most part the problem was a lack of attention to detail on my part. Soon to be installing Aquatherm omega he 30 gassification boiler with a 50 ft. run to my shop. Question, can I run my well insulated pipes along the outside wall of my shop? They will be protected and will not be in the way of any actvity in the area. Any thoughts?? Thanks Steve
