OK, I got the idea from PapaKeith and Apisbees, and saw a variation that I liked, so here's mine.
Given that I am long winded, here is a primer.
I have around 65 hives, and hope to someday have a dedicated honey house large enough for my needs (my first one was waaaaaay too small).
In the mean time, I have a pile of full supers coming in at the moment and no where to really put them. I have decided to "store" them temporarily in the unheated honey "shed" I now have. I saw a nice heating cabinet at another small commercial keeps that I kinda liked, and figured it was a good temporary fix for me.
I bought 3 - 4 x 8 sheets of this 1" Durafoam product. It has a sprayed on plastic film on one side, and a foil film on the other, so no off gassing.
I had some solid pallet scraps kicking around that I thought I could use as well. I built a temporary cabinet 6' wide, 2' deep, and about 5' high, and lined it with this Durafoam stuff. The "front" is just 2 pieces of the Foam sheets for easy placement and removal.
What I will do is as I need to extract, I will bring in a 18 or so honey supers, stack them in the cabinet and use a couple of light bulbs and a small fan. The cabinet that I saw I had shelves, 4 - 100 watt light bulbs that were switched to come on 2 at a time, and a small bathroom fan that circulated air. I can preheat my supers so they extract easily, and as I set aside uncapped frames I can consolidate them till the end, and then shove a dehumidifier in there to finish the job.
The fellow that had the nice one also stored all his honey in 30 lb. pails, and when he needed to fill his bottling tank, he just set a half dozen pails in his cabinet and 24 to 48 hours later they were liquefied.
This is just a temprary solution till I have a heating room for storing supers (a fellas gotta dream eh), but it didn't cost much except my time, and $15 a sheet for the Durafoam (total $45).
You can see my "old" system of using an empty deep with a trouble light next to the cabinet, but it was really only good for a few supers.
Any comments, flaws or problems you see, please feel free to point them out
before I make fool out of myself.
