Hi Peter, excuse me for butting in as this is just my second post on permies.com. I´m facinated by this design as it incorporates mass without all the ducting and bench making, which is great but isn´t suitable to all situations. Would you mind clarifying some of the materials used in the construction. Johan mentions that the mesh is firstly coated with ¨some sort of terra cotta¨ What´s the purpose of this layer and what exactly is it. He also says that the outer layer is Loam, Wikipedia ¨ Loam is soil composed of sand, silt, and clay in relatively even concentration (about 40-40-20% concentration respectively)¨ or is it actually cob? Thanks in advance. Stephen.Peter Berg wrote:

The barrels were covered with cardboard first and after that with the wire mesh. This type of mesh is called lath, I am led to believe. The cardboard was done as an experiment and it turned out to be a very smoky business because we couldn't keep the cob layer airtight... In retrospect, we should have used ceramic paper instead to compensate for the expansion of the barrels.
The stove did what was hoped for, by the way. The top barrel radiated lots of heat from the first minute and the covered part got hot enough to burn one's hands despite the 2" layer of cob. This layer could be as thick as 4" I would say, even 6" maybe. But that hasn't been realised yet.
