Wood powered Gasser??

I think the burley stove is double-glazed. The fire chamber is also excessively-lined with firebricks to ensure a high combustion temperature.

Yes, Desp, catalysts work on woodstoves. The Americans use them a lot. You got to bypass them until the flue gases are hot, otherwise they clog up. Also, you have to be very careful about what you burn - there are a lot of chemicals that can kill catalysts (eg heavy metals to give one example) - so if you start chucking any old wood on the stove, you end up with a dead catalyst pretty quickly. So it's high quality logs only. None of this pallet rubbish!

The Walltherm stove  has an extra flap between 4a and 4b  on Billi's plan that can be used to increase the draught,  by shortening the heat transfer area, if the flue is too cool.   I am probably going to install one soon.   My chimney is quite  short, only about five metres above the stove, so  I may have to do something to increase the draught.  An angled entry to the flue and perhaps an extension  to the chimney  by way of a tall cowl might help. I wonder how difficult it is to initially get the flue gases up to 300C?    I want to use the air inlet to help dry wood by drawing inlet air through the wood store.  There is a an insulated version that the Irish  agent didn't know about  that cuts the heat output to the room down to about 3 kW instead of 5kW.   This should be OK for a daily four hour burn.

Yeah, it would be nice to keep the glazed door and line the other 3 sides and the base, do you reckon the glass would be up to the job? Maybe some of the secondary air heat exchange pipery could sheild the glass a bit. I am going to try and knock up a sketch or two for your perusal.

Don't know where you can get Corning 7913 from but a melting point of 1530C should be high enough.

The other option is rocket stove mass heaters (google: ianto evans rocket stove), they are very efficient, and if we get the house that we are currently hoping for, then I will most likely build on as the main heating appliance, ideal for running on coppice wood.
