My friend turned me on to this idea last week. I was pretty impressed so I decided to build one of my own.
I already had the 2x6s and some old sliding doors. I am predicting a final cost of $50 to $75. If I decide to use solar panels to power the fan it will drive the cost up a good chunk though.
Here is the sliding door I started with. I decided to go with a single pane set up because the door as it sat was ridiculously heavy and the seal was broken making the glass foggy.
Here is the glass taken out of the frame and the double pane taken apart. It was a beast getting the seal cut.
This is the framework. I don't have it all screwed together yet. I cut a channel in each of the long 2x6s for the glass to slide in and I want to test fit before I get any further.
The glass is 34x76 and it will hold 192 cans. The cans will be painted black like all the other builds out there but I am considering using a either a reflective insulation or just aluminum to line the box with. I think the reflective surface will improve the heating of the cans. Any thoughts? I am still trying to decide how I will close up the header and footer but that is a ways off. I was limited on space so I am going to be stuck using 4 inch pipe for the inlet and outlet. I found a 92mm computer case fan for 16 bucks that I will put in the footer to suck the room air through the furnace. It is rated at 119 cfm though so I think it should move a decent amount of air through.
