George, Can you explain why the angled floor pieces are staggered? Is there a practical function that I'm missing, as it seems like they would make it that much harder to clean with all those nooks. There is a photo you posted much earlier (4th picture) showing this same area where these same angled bricks are all the same length and ending at a metal grate. Curious.

I noticed that the height difference between the inclined parts of the firebox floor lets the primary air invade the wood stack and on the underneath . In the first part of ignition the primary air flow besides the walls and create turbulence when meets the secondary air jets
Sorry , I forgot to draw the cleaning  hole under the metal plate .
This firebox is made by refractary  plate , the first one has bricks dimentions . So , my friend can  choose the better version , depending on the materials available .

So what I think your are saying is that when the wood is laid in the firebox, the staggered bricks provide air channels for the primary air to pass under the fuel and upwards along the sidewalls, meeting up with the secondary air ports. Similar to an open fireplace with a metal grate used to elevate the wood off the floor.

Good morning .
A little important change.
My friend doubled the back of the firebox .
Over time, he noticed cracks in the gas output area, the area where the temperature reaches its highest rate.

There will be a dumper for direct smoke way , to heat fast the chimney .
An air channel is already made for the panoramic door .
There are also two air slots at the gas output from the fire box .
let's see what materials will use for the catalyst... or refractory fine plates, or some iron flat bar .

Look up a German company called "Lehm und Feuer" (Clay and Fire). They have been creating works of art wrapped around fireplaces for years. Their gallery of past projects is inspirational to say the least! Best of luck

Sorry, everyone.
The owner of the house will be gone 10 days . My friend will teke a break during this time to this work only .
It will transport materials to the new location , where he will build a new stove on two levels. Stove 2 in one and also both level will have separate firebox .
Down stove should be able to heat both levels , top stove will heat occasionally .
Will be black oven , two exhanger 25kw bot , boiler with coil 300 litres and buffer 1000 litres .
For me, the project itself will not be easy to make it , but to cut hundreds of refractory bricks ... wow !!!
I'll be back with new images of the work after the break .
Best wishes from Romania !
