I've been meaning to buy a chest freezer for a while now (just missed one for $100 on Craigslist!) as we eat a lot of venison and run out of room in the upstairs freezer pretty quickly. The chest freezer will sit in the utility area of the basement, so as it is I shop the scratch and dent isle at the big box stores because I don't really care what it looks like as long as it works. Energy costs have me thinking though-would it be worth it to attempt to improve upon the insulation of the freezer by supplementing it similar to the idea of a hot water heater blanket in reverse? I was looking at the Reflectix product here and thinking of using it in a similar fashion to the way they insulate HVAC ducts: http://www.reflectixinc.com/images/uploads/allpdfs/f62 duct insulation submittal 0107.pdf Of course I'd need to take care and not obstruct the ventilation air to the compressor, but it wouldn't be difficult to cover the rest of the outside of the freezer. The average freezer has a surface area (not counting the underside) of about 85 square feet. I can get 400 square feet (48" x 100' roll) of Reflectix for $100, which would essentially allow me to cover each surface four times with airspace in between, which, according to the installation guide, should give me at least an R-8 rating if not more. That still leaves the underside, but I think that would be better served by raising the unit on blocks and placing fiberglass batts underneath as there won't be any real "radiant" heat coming from the floor. I have plenty of fiberglass insulation left over from remodeling my basement as the previous owner even insulated interior partition walls which I ended up tearing out completely. So, if this little project only costs me $100 and a Saturday afternoon and I use the freezer for as long as it lives (15 years at least), is it worth it?
