Hey, I admit I’m a newbie and I probably deserve and will benefit from these unusual discoveries… but. Anyone seen this configuration before and what do you think? Yes, that is a photo taken from the crawl space of the heating elements. The air passed directly over the elements into the “wonderfully warm” crawl space. (85 degrees for the living space to maintain 75). The foundation walls were completely covered in the fashion shown with R-19 and as such unobserved for structural issues.
