I got my Silver Star add-on hooked up through a roundabout means with a long 8" duct meandering through my cold crawl space about 25 feet. My output temp at the big register is only 93 degrees! So I took a digital thermometer and made some readings. At the duct outlet, about 4" above the furnace with a medium sized fire burning I am reading over 140 degrees, my thermometers range ends at 140, so I am going to guesstimate it's 145. Down in the basement at the point where my duct connects to the cold air plenum I am only reading 94. So in that 25 feet I am losing over 50 degrees! Would duct wrap make a significant difference? All this heat is going to the crawl space, which is kind of good because it keeps the pipes warm, but I can't get the house over 67! Im thinking of wrapping part of it and seeing how it works.
