"Upside-down" fire: gasifier

And there's more!

Home-made little gasifier

Works the same as the fan-driven woodgas camp stove that I did a video review on some years ago... It's my fourth most viewed video, out of nearly 200! Sadly they aren't for sale any more http://www.youtube.com/watch?v=Z6evSvYH_RA

We have only brushed our flue out twice in seven years as we never bank the fire down. We only ever burn it at full whack or let it go out completely. The flue is a modern insulated block design so it keeps most of the heat that goes up the flue in the flue. We have a flue thermometer and adjust the temperature of the flue by opening the top covers and the oven door to change the amount of heat that comes out into the kitchen. The kitchen doesn't overheat very often because of the high thermal mass of the house. We adjust the output of the stove by varying the time between rechargings, more often keeps the fire going hotter and less often allows it to cool down a bit more.

There is a collection point at the bottom of the flue for any soot which flakes off the walls of the flue and we empty this usually only once a year. A visual inspection of the flue is possible through this opening and a clean has only been necessary once in the last few years. We did have a problem in the early days but think this was due to the flue being damp still and us not getting the hang of burning the stove hot to burn off any soot accumulation.

I think its called Holistic design!
