Can you please post a pic or to of the internals where you connect the boxes?
I didn't photograph the assembly process, but it's easy enough to figure out. Take the big box, which is your heat collector/drying area, assemble
it, then take the dimensions of your space heater (height x width), and mark in pencil the size you need to cut out. The cardboard tunnel for your
heater is inch bigger than your heater. That allows 1/2 inch on each side to prevent overheating.
Also, do you seal around the heater inside the smaller box to prevent the air escaping?
Nope. The heater is injecting lots of ambient heat into your collection chamber. You want a loose fit to remove your heater for other uses, plus, it
just sits there. No fasteners required, as it's the simplest design I could think of. Air-flow is the key, and remember, the excess heat is also
being absorbed by the surrounding room, so you are still using your heater for it's original purpose, with a beneficial side effect.
I have been doing a lot of research lately on storing food items without electricity.
My only issue with the design is the need for power. I was thinking though... in a SHTF situation the power could be acquired through some "black
ops". If solar panels can be added to electric cars to run the air conditioning without using the main batteries, I am sure one could be "acquired"
and adapted to power some small items like your dehydrator.
My design can be scaled back if needed. I could run a 300 watt model heater, instead of 1500 watts, and I have an inverter for my truck that produces
500 watts, so I could easily take the dehydrator on the road, if need be.
If we ever loose the electric grid, a redesign is required, but it would be a wood fired version utilizing the same parameters, with air-flow
determining the heat produced and the drying temp. I'd probably make a sheetmetal version then, and place the heat tunnel over the edge of the
coals, and let induction run it's course, with no fans or electricity required. The sheet metal version wouldn't catch fire, like the cardboard box
Adaptability is the key to survival.
