<br>
Yes I'm using an air feed from below the grate. The hopper lid
was designed to be air tight. Its made of heavy steel plate
welded onto some thinner metal strap that is on edge, this closes
down onto some asbestos rope that is sat in a channel.<br>
<br>
I'm not sure if it is completely airtight. When I was burning
wood chip in the stove I noticed, once, that the fire had spread
up into the hopper. I guess time will tell. I have been
considering fitting some kind of latch to pull the lid down tight
onto the rope. I've done this to the front door since I took this
picture during the first test burn in January.<br>

It looks great but are you not concerned about for lack of a better description , "back burn" up into the hopper as the back combustion chamber wall gets hotter. Long a go in this list there was mention of a Canadian inventor who developed the idea of back feed like your stove. Anybody recall the person ? Maybery ? Another person, from the US part of the Americas , tried the same idea with vertical stacking of the fuel (in this case hollow core briquettes) and had pretty good success as long as the hopper lid (feed tube in the case of the briquettes) was absolutely kept airtight. In both cases air feed was thru separate vents, not the hopper.
