masonry wood stove model

Good morning .
I am from Romania . I like very much the stove from attachment and I want to built it .
It has anyone any idea how it was built this stove ? Where  can I find o drawing or a diagram that can help me ?
Thanks a lot .
Best wishes from Romania .

Hi George,    Welcome to the place where dreams come true.
A most lovely stove to emulate indeed! I would say its a batch box type heater. A great place to start your research is at:batchrocket.eu
There are lots of things to consider, but once you have an understanding of some of the basics, come on back and ask questions. I'm sure we will have plenty for you too.

Good afternoon Mr Gerry .
I hope I understand well the operation  of the wood stove . I did the drawing and the stove work good .
And not this only .
Of course , we always learn .

And wood stove with two levels ...

Hi George ;  
I'm confused (normal) have you already built this stove ? Or did you find photo's from somebody else building it?
That appears to be  a masonry stove, not a batch box stove.

If you are still planning on building a stove, then the website Gerry recommended ( http://batchrocket.eu/) is a great site.  Lots of good information and there are all the plans to build a batch style RMH.

Yes , I did the drawing and my frend built the stove .
It work s good , but because the secondary air is not enought , need tom burn less than expected quantity of wood .
The first test done by a frend engineer ...

Now , my brother - in- low wants a stove like inthe  image sent , but I do not know the inside compartiments .
I can do a drawing of firebox , but i need to know the smoke way to do the right drawing .
No matter the tipe of firebox ...

In my country people work , wife , husbant also ...
So , they are busy and start to prefer a wood stove with acumulator in walls , and a firebox that should not be  fed often . So massonry stove are most comon .
Of course , besides the boiler stove .
I have in my home Viadrus U22 . Not the best but I made a few changes .

George,  I've contacted our batch box/masonry heater expert to see if he can look at your system you would like to build. Looks very interesting and will enjoy any information that comes out of it. Beautiful work by the way!

EDIT: He's quite close to you too!

Thanks a lot .
I am looking forward for some informations .
I will post the sketchup drawing after I have done , for discussions .
All the best .

Good morning to all .
For this stove I did first my drawing . My friend made the stove for his home . The exchanger it is huge , 20 kw . In the present we try to find the best water exchanger , after I strongly supported to use two pieces , one big power situated over firebox , and secondary one situated in smoke way , with role of recovery .
In the link you can see the big work of my friend ...

Have a nice day .

To believe me , I attach some pictures of drawing , sections ...

In present , in firebox , we changed rectangular stainless steel pipes with channels ( in drawing you can see pipes with long channels ) and use stainless  pipes with round holes . Because the air was not injected , the air fell in the firebox and do not help to much in gasification process .

George,  That is some friend you have there! A fantastic build indeed! ....and I must tell you that this is definitely out of my league. Unless anyone here can help our friend George, I'm going to recommend you go take a peek over at donkey32.proboards.com where they specialize mostly in rocket stoves and masonry heaters. Good luck!

wow !!!
I do not deserve an apple just for drawing , thanks a lot . I will send to my friend who works to transform a drawing in stove .

Thanks dear Mr Gerry .
I hope I will find some help to design the stove . So , my problem is to put on paper a good drawing , but I have never done before a stove with hot bed .
The design should be good , with double way for smoke to not heat the bed to much .
I think the stove should have about 3 kw . For my brother in-low ,  the exterior design and hot bed are important . Next week I will start to do a base drawing .
Maybe I will use a batch box ...

Good afternoon .
I am steel waiting for answer . Until then , i will post another masonry stove that with remaining in the drawing stage , because the materials are more expensive than a cast iron boiler .
The fire box can be replace with batch box and on top can be built another bell . The possibility are many .

Hi George,   Peter van den Berg is probably the most qualified to assist you that I know of but in the meantime, thanks for being patient. 🤠
As with most (all?) permies staff, he is a volunteer staff member and probably enjoying his retirement, so we are always grateful when he joins in the conversation to give us young chaps a little advice!

Have you enquired in the proboards forum? If you have, could you provide a link here as I would be interested in following your build.

I want  , from a long time , to ask if somebody try to fix in rycer of batch box a pipe with secondary air from ecterior , and dumper to adjust the quantity of air ?
Maybe it is possible to have a secondary burning of gas  . On top the calalyst ,  made from stainless steel plate 2-3mm , will burn the rest of gas if is very very hot , and the hot air comes close .
That means the flame has to go through the catalyst .  

Good evening .
The  drawing , as a first base .
A simple scketch of stove . The fire fox will be normal one , with primary air from inside and secondary air from exterior .Lateral the wall will be double for secondary air .
Both sides have two rows of square secondary air holes .
The smoke comes out of the furnace and down by counter flow left side , and passes under the ash to bench .
One part off bed will cover the furnace .

Base stove with secundary air between firebox walls ...

The base from my friend start to built the stove .

The first level of fire box .
Secundary air from exterior will be heat in a corugated stainless steel tube, 125mm diameter .
The tube will be buried half in the base . The air enters from the outside, crosses the first lower bell, follow  the bench and enters under the ashes.

The base of the ashes will be a metal plate , 6mm thick .
The plate, heated by hot gases that pass under neath it, will heat also the primary air .

The ash and entrance of air ... separate room .

George,  I'm curious what type of material your using to (I assume) cast the parts for your stove?

... the base of the fire box with primary air cutout, the place where the grill will be for the elimination of ashes.

The first row besides firebox with secondary air input .

Also the first row of fire fox wall ...

Behind the firefox you can see the counter flow channel , the way that guides hot gases under the ashes .

Refractory bricks have the dimensions 230/115/60 mm and the refractory and refractory plates have the dimensions 500/340/60 mm .
Because of insufficient space , the fire fox walls  will have 60mm thickness .
In the next row of fire box will be first row of secundary air .

Depends on my friend's choice. But all the walls , inside , will be refractory bricks .
Exterior , if not using double wall , first coat will be special adhezive and triple rows of fiberglass mesh .
Between the bricks will be use special  paste resistant to high temperatures , for stove , ovens ... but not this only .

Your stove George is so well thought out (in combination with a really, really good experienced friend) is going to make it enjoyable just to sit back, relax and watch your progress so we can learn from you! Photos of your progress would be nice too if you can pretty please  :)

You are very nice , but I have to learn a lot . So all these apples are well deserved by my friend , all , no exceptions .
Also the pie ...

The wall will be double . Exterior ceramic bricks , inside refractary briks , between 5-8mm expande space , for sealing, glass wool .
So , for exterior cover ,will be use this time three rows clay= one part refractory clay and 3 parts sand, 1 part hemp and 10ml silicate(water glass)at 40kg clay .
For finish , yelow clay plus fine sand .  

The final base ... I forgot to post it .

A sections of fire box .
Each side has three rows of holes for secondary air , each hole has dimension 20/20 mm .

New section ...

start job...

Final firebox .
Panoramic glass door will have separate air that will wash the glass , even if secondary and primary airs are closed .
Please , do not hesitate if you think changes should be made .
Thanks for help .
