Update: We've just finished the build of this DSR3 with a 200mm system size, bypass and open bench. All pictures off the build can be found here: drive.google.com/drive/folders/1FqSqoeGr99Cv1M45tRamwELaXmbF2oJ0?usp=sharing


In the video we've just finished the build, the stove is still wett and you will see some condense on the looking glass.

Dimensions: 

Total height 170 cm 
Width 110 cm on the front
Bench 150 cm long by 60 deep

We've used 90mm compressed earth blocks as the outer skin of the bell (oskam-vf.com/en/clay-products/compressed-earth-blocks) and halfway we've switched to a double skin bell. 40 mm earthblocks on the outside, 40 mm chamotte stones on the inside. Leaving 1 cm gap for expanding. 

There's also a bypass just below the exit port of the dsr 3 heatriser. 

We had several online meetings with peterberg discussing this build for which we are truly grateful. Thanks a lot Peter, credits for this design go to him! The design is really simple and logical and buildingwise a great improvement.

Please note that this build is still a test. We don't know yet how it's performing. 
The heater is now drying and we are planning to invite Peter to visit this stove together with his Testo equipment to run some tests and get more information on how it's performing. 

In this way we are hoping to contribute in a usefull way to this open source system and the further development. 

That's a beautiful build! I love the simplicity of the chimney stack and bypass. Do you have any photos of the bottom portion of the first bell where the chimney mounts near the ground? Also, what is protecting the chimney from the high temperatures when inside of the bell like that?

Hi, thanks for sharing. I would like to experiment with the DSR3 and I was wondering if it was possible to replace the vacuum ceramic wool tube with firebrick? Thanks

No I dont think you can because the tube needs to be insulating, you could cast one from insulating refractory ready mix.
