Wow. Thanks for the update Radek. That is an incredible build, lots of challenges, not to mention it's just huge. Very fun to follow along, it looks like you'll be having a fire before too long here. Amazing work.
yes Matthewwalker lots of chalenges been ovecome with this stove,actualy i like chalenges ,what doesnt kill you,makes you stronge ,some says.So im almost done with building, now will come the fun part of plastering the stove and some playing with finnal design.The chimney will be done by someone alse,it will be triple wall stainless steel chimney about 7m tall starting on top of the second floor bell.That bell by it self is 1m tall so i guess there will be around 8 m of active chimney- starting from the floor of the second bell.I have a question thou, the vertical channel connecting the first floor bell to the floor of second floor bell is around 3.2m tall,so should this 3.2m be added in to the active haight of the chimney,not sure about it.But right now -no chimney-when i light a paper in the fire chamber -no door-the smoke is easylly finding the right way up the connecting channel.Good sign.
Andy yes i like to do the shelf this way,its easy and the top of the bell could be exchanged in the future if necesery,because the top slabs are not build in to the skin.it just flows in the fire wool on top the shelf. Your first question-none of this two,,normaly i would use fire brick slabs just because they are easy to get around here.But for this stove i wanted something lighter and with less mass-acumulation.So i have used synthetic cordierit ceramic slabs.This material is quite pricey,but i have found recicled ones for really good price .http://s101.photobucket.com/user/snake11112/media/two%20story%20stove/DSC04831_zps8497ad37.jpg.htm For sticking the fire wool to anything ,i just use fire clay slip.Im sure ordinary clay slip would work as well. For lining the vertical channel i have used something called Silca aroud here.Basicaly its a calcium silicate board rated up to 1250C.I have used some kind of fire glue witch comes and is suggested for the calcium silicate board,one thing thou,the boards are really dusty,so you have to wet it a lot before aplying the glue.Than i used three screws on each side of the 1m long section. hope i could help
hi Eric there are two slots on each side of the fire chamber right behind the door.Yes,they are for the primary air.The problem around here i keep coming too,are really well insulated houses.So,usualy i have to bring the external air straight in to the fire chamber to avoid draft-cross wind-in the room.You can see on the right side of the stove a pipe which will bring in the external air ,first under the fire chamber and than thru this slots into it.The pipe will be connected to chanel and to outside.We had to have a hole driled thru the 80cm thick rock wall.The hole for the air is 12cm D . i guess i have seen it done this way by Alex Chernov.
Hi radek, Thank you for the timely explanation. Our house is not so tight, so I suppose I won't go that direction.... Just thought maybe it also involved air washing the glass. Say, your 2nd most recently finished heater, the one with the white plaster finish- can u share your recipe for that mix, or is it a trade secret?! Either way, I really like it, and I know it would help the w.a.f.! I appreciate your response and sharing your experience. Eric VW
Hi Eric VW no trade secreds here,The bottom part of that heater-the part made out of red brick-was wraped in to Jute-Burlap-cloth.Basically i dip the burlap cloth in to a water ,squesed it out, than dip in to some clay slip,and stick it to the wall of the heater.Than by hands just smooth it out so the structure of the brick under it is somehow visiable.After that i took some clay slip and brushed it on top of of the burlap so the holes in the mesh would get covered.After it did dried out whole heater was painted will realy good quality Lime -5 years old.No, i didnt make the lime my self. The top part of that heater-the part build out of fire bricks -has some fire mesh first,followed by plaster made out of fire clay and sand.1-3.Than painted with lime. How you can see in the picks above,im wraping this heater in the burlap cloth as well.I somehow like it ,and it makes a realy good base for thin layer of finnish clay plaster.

daniel: in my experience as I am working now on something of that nature, I have thought of making a heat exchanger and distributing the heat through vents using a slower fan. Now after a few years I realize that mass heaters give out primarily radiant heat, for

vesuvius: Do any of you have experience with using the glass from home oven doors on a rocket stove? I'd like to have a viewing port on my stove but don't want to fork out for new ceramic glass. Any thought as to whether it would take the heat of a rocket stove?
