I debated this with a refrig and heating
professional. We finally came down to-
1. If you have the space- multilevel blueboard and a good shipwright is the way to go. Get your refrig from R-parts or someplace similar that specializes in well done simple refregeration. Because in the end- its the insulation
that makes all the difference. Buy your vacuum panels
only if you really know what you are doing, lack space, and are willing to invest tons of $$$.
2. I am redoing my frig. I have a space about 3 feet by 4 feet. I will a foot on all sides with blue foam which will leave me with one foot by two foot by two foot- and a daily drain of about 20-30 amp/hours. Not much of a frig? I disagree- because I do not need that much. Basiclly enough to keep my dead seafood and meat fresh- and I don't eat that much meat. But I want the stuff I have to remain fresh.
