So yesterday, I got to play outside a bit more. I worked on my Pocket Rocket Heater some more. I tore it apart, to see where it got hot, and where it did not and to add 1 more can to complete a burn chamber. I also insulated it with perlite.
I couldn’t find my baling wire (old timers will tell you it’s duct tape 1.0) so I used a bit of floral wire. Not as sturdy, and I expect it to be too light, so a good burn will melt it enough that it will break, but this is just a test unit, right?
I also poured perlite all around the inside cans to insulate the stove burn chamber area. Of course, I forgot to take a photo of this step. Bummer.
I am quite happy with how it all works. I like fire, and I like making things from junk.
My future plans for this particular unit is to either run a longish near horizontal 4″ exhaust out a window or maybe do the full on inverted chimney. This involves a 2nd, much larger chimney placed around the current one with a cap on top. A horizontal exhaust is then attached to the bottom of the outer chimney to vent the gasses. This allows the whole thing more time to release more air into the space that it occupies. It’s worth trying to play with, that’s for sure!
