Underfloor radient off BB return
<span style="font-size:12pt">Has anyone had experience with the Ultrafin product for underfloor radient? I have family room with finned BB originally designed for 180 degree water. The room has a fair amount of windows. I’m now using a modcon with ODR so my water temps are lower. The amount of BB just doesn’t provide the comfort. Heat loss is 13K. I have easy access to the crawl and want to take the return from the BB and run it through PEX under floor. Floor is ¾” OSB with 5/8” maple flooring. Protruding nails make plates impratical. Currently the uninsulated ¾” copper supply and return lines run in an enclosed insulated joist bay. The dog and cat have found that spot. When I ran 180 degree water I had to insulate the pipes because I was getting some movement in the maple flooring. I do not have that issue with the lower temps. Is there a better way? Thanks in advance.</span>
