I am installing my 1500 in a 10'x20' shipping container that will be about 8' away from our home. I'm planning a fabicating a well insulated box that will be about 3' off the ground to run pipes to the crawl space through one of the outside vents. I'm weighing pro's and con's of running black pipe to the crawl space with the manifold under the house, or have the manifold, pumps, etc, installed in the front of the container with the pex lines going through the insulated skyway, if you will. Any thoughts? I'm also considering using DiaNorm wall Panels and was curious if there was any experience with these or other brands. Thanks again for your help.
