I was told that using cinder blocks as a base and filling their holes with perlite would work as insulation. Then Peter Van de Berg suggested to me that i don't stuff the holes with the perlite material as the air gap is crucial for the insulation.Then he suggested to me that i use on top of the cinder blocks ''a ring of bricks'',an infill of perlite clay and on top that i build the firebox. The thing is that i can;t visualize this. Can anyone help me?
Beginner question. I am assembling materials to build a BBR. Which design should i apply for the base structre in order to achieve an air gap of 4 inches. Can you give me some practical ideas and what to use to achieve this?
I want to build a batch box heater 150mm heat riser diameter. The dimensions of the firebricks in my area are 22x11x6 cm. So for example if i stack vertically 3 firebricks for the firebox it gives a height of 33 cm instead of 32,4 cm as mentioned in the spreasheet's dimensions for the 150 mm system. Now in this case should i cut the firebrick so that it matches exactly to the 32,4 cm height? Or should i scale down the initial system to perhaps 145mm diameter for the heat rise so it fits better?
Would a straight firebrick core be sufficient for heating a small house(not good insulation but it is just a house of 48m2/3 rooms)? My floor is tile. I can't build the firebox on top of it.Right? Do i need to put an additional layer of firebricks as a base for the firebox? Do i need to put any other insulation to the floor?
Last question is how much clearance should be between the firebox or the bell and the wall? How many cm of insulation of perlite do i need to put all around the hot firebox?
Thank you for any help! Btw my location is Greece and it is the first time we had such a cold winter in January.Totally not prepared for this,and as for the traditional fireplaces they are a waste of wood for the most part.It actually costs like 2000 euros to have someone build a fireplace in a new constructed home.
panos: Some fireclay products say thy exhibit resistance up to 1000 celsius.Would that be fine for a 150 mm Batch box rocket?Would it be better to search for reistance up to 1200 celsius?

idahodave: I'm getting ready to build my first RMH, and have some specific challenges. First one is that the site has a high water table, which in February got as high as 8 inches above the projected base of the heater. Any suggestions?

panos: Can someone make a sketchup file for the support base of a batch box rocket as per Peter's van De Berg following reply:

panos: those pumice cinder blocks are better suited to a base support. On top of the blocks a ring of bricks, an infill of perlite/clay and the firebox and maybe even a bell on top of that. If possible, arrange the blocks in such a way that there are channels

panos: under the whole of the heater so heat won't accumulate under there but can be vemtilated away by air currents.''

SilverFire: Yes, our designs have moved from the experiment design to production, as with the other stove models that were listed on this thread. Hopefully this will inspire others to continue to improve stove designs as we have done.

permaculturebob: citrus paint removers --"citra solve" is one and Walmart distributes another--non toxic fumes, softens tough barrel paint--sometimes it takes a couple applications and some scraping, but I prefer it over sanding and burning

martinm: Hi there ! I need chart / comparisson on : RSMH vs mass produced wood burning stoves. I need to write a proposal to local govt. to convince them on choosing Rocket stoves for supplying families in poor neighborhoods. Thank you Will look through the threads
