Definitely the mother of all masonry stoves web sites,there is a book : A 
gide for practitioner by Heinz Maresh,book from 1943.There is almost all you 
need to know about technical aspects of kachelofens

http://www.dataphone.se/~ncteknik/We_are_setting_up_a_Swedish_ceramic_stove.html

this is what a kachelofen is,the best site I have found on the internet 
,detaily pictures of a construction of a swedish traditional stove.Look at 
the back of the stove - it is built from ordinary bricks.The mortar is clay 
sand mixture 50% / 50 %

the missouri designed masonry stove.

It can be definitely build "do it yourself".When you understand the principle 
it is stupidly easy.Just playing with the mud,like a kid.


In Serbia the tradition says to mixture clay with some grain husks and work it 
in quite wet condition - the clay I mean.
Basically,use ordinary bricks,firebricks only in the hotest part -the 
firechamber and first chanel,then ordinary bricks,make some chanels that 
moves the hot gases around,use two layers of brick -the core and the outside 
,dont complicate to much - voilla, you have a masonry stove.It doesnt cost 10 
000 $ but it will work excellent.This cheap stove will not last hundred of 
years like a 10 000 $ one ,depending on the usage,but 10-15 year almost 
sure,probably longer,there are some kachelofens here that have lasted for 30 
years without rebuilding them.When its time is up,just torn it down and 
rebuild it again with some new bricks.Or just youse firebrick for the whole 
core of the stove,and it will outlast you .I think it fits great with a cob 
house,no I know it works great with a cob home,its also a tradition 
here.Cheap.I am planing to make myself one just for experiment and I let you 
know the results,but I doubt that there will be any problems.As I have said I 
have used kachelofens mortared with ordinary clay,some tiles broken ,some 
missing and replaced with a ordinary roof tile,actually two rooftiles glued 
with clay ,and no problems.I have built 10 kachelofens,so you know I know 
something about this stuff.
About making tiles(kachels,fliese) for this stoves,I have experimented for a 
year about it ,but so far I have not resolved the problem of cracking of the 
tiles during drying and baking in the kiln,I think I know what is the problem 
but dont have acces to some equipment.It is hard to gain here any knowledge 
about pottery,no books,no one willing to help etc.Tiled stoves can be real 
art,but tiles are not necessary, all you need is a fire resistant core,and a 
heat storage.
