Very nice looking, Radek. What did you use to plaster it? Clay+sand? Any fibers
As i see, the plaster touches the barrel - no cracks?
The oven: the bottom is only metal barrel plate? How does baking performs?

thanks Matthewwalker for nice comment i really appreciate it.
Hi dvawolk the brown plaster is clay slip mixed with hors manure-no sand i my case.I have mixed half clay slip and half hors manure and let it sit over night than mix it again a bit.I gues this is call Litema in India.The white stuff is pure caolin clay mixed with fine sand and some flour paste and a pigment.Whot i usualy do to protect the cob and the plaster against cracking,I glue some cartboard paper on to the barrel-with flour paste while the barrel is hot .This way i create an expansion joint between the barrel and cob-plaster.In most cases it prevents the cob-plaster from cracking.
The bottom of the oven is only the barrel,when i bake i have to sit-lift up- the baking pan above the barrel so it does not burn the food i baking.Otherwise the oven works realy well,i have done wegies,fish and even cakes in it.Usualy i close the door of the oven one and half hour before baking ,i load the stove with wood and when there is only a little bit of fire left i start to use the oven. Hope it helped and thanks for comment.

Radek, That's a beautiful design and I envy your finishing abilities. Is the exhaust pipe in the wall??? The first picture shows it on the left...where did it go...do we see the top of it above and to the right of the barrel?
You have made this a work of art! Do you like the way it heats your home?

Hi Lightlover Thx for the comments and yes sometimes i can be a detail freak.Here is a pics for you from during the build.Yes the stack is on the right side of the barrel but there can be seen only the black elbow.The rest of the stack is buried in the cob.Basically because the bench on this 20cm/8'/ heater is little bit to short i wanted to get more heat out of the system ,so i added more mass around the barrel and stack.Love ,peace ,Happiness Radek Attachments:

Looks really good radek..... would you mind posting all your pictures from the build?
I will be doing one similar to this in the near future.
Now the copper manifold, is that for heating water? Kinda a small run no?
I Am reallly thinking about heating oil in tubes in the heat sink.... the circulating that into a coil with a small fan and or some pex under the floor of the home to add some even heat through out the home. Oil retains heat very well....

hi agatto2 yes the copper run thru the bench is not too long and if i would have more money at the time of build ill do it longer.The loop is hooked up to my water heater.In the winter season when i make fire every day the water temperature will get to 50C max.Thats ok for shover .But this water temp would be ideal for floor heating for sure.I will post every week some more pics from the build,but not all because i have a quite lot of it.  |

I was thinking that if you ran cooper tubing probably 3/8 and coiled it around the stove piping it would increase the temperature via surface area of the medium being used to heat.
Pretty sure on mine i will coil around the whole stove pipe assembly with 3/8 copper pipe, then use a Peristaltic Pump and try to pump oil underneath the floor joists. Will use pex under the floor. This should increase heat retain ability 10 fold over water.
For water heating we are in a sunny area and will just use a vacuum tube heating system for hot water
