Hi Shutt
Send me your email I will send you the plans as well as photos of the stove, I go to a hardware store to look for copper tubes and fettings for my bubbler I bring my camera you will have a series of photos of the stove which are on sale (smaller than mine)
No the engineers are not idiots nor the French, nor the others
but the engineers as the journalists they have bosses who ask them to design products salable locally, he manufactures the modes he decides the quantity of wood that you are going to consume, he does not care whether it is economical or not the only thing that interests them it is $. The stere costs over $ 80 delivered here.
We did not invent this kind of stove, it was the Swedes the first, it happened here in the 70s and full of skilled handymen started businesses of this kind of economical and profitable stove. currently these stoves are perfected
Efficiency comes before fashions and it can be beautiful to look at too. more than 20 years ago I provided the plans to a French from Lorrainne to make this kind of stove, he never built one
the answer is not salable here people prefer fireplaces, so go and pile some wood in it and stand close to the stove to feed it.
There are those who like to put logs in the hearth, the ceremonial of the fire in the hearth, yes it is beautiful a vigil. but as heating for a winter it is slavery, I much prefer to put 2 logs and heat all night at -20 outside, in the morning two more logs and it is left for 6 hours.

yes, I'm interested to see it. but now also, our stoves or our fireplaces hold the night. On the other hand, if you want to heat the whole house, it must be well insulated, otherwise that is not enough.
But then we have the Austrian kacheloffen, or we put logs of 1m

About 38 € (about $ 53 CAN) per cubic meter of 70% oak and 30% hornbeam / beech cut in 50cm to pick up on site by my home.

But I'm sure that in Quebec wood can be found a lot cheaper than $ 80 per cubic meter, isn't it?

@Andre: I'm interested in your photos too.

Hello Benoit
For the volume figures of the wood it is not sold in stere
and I made a convertion a little fast, the usual measurements here come from the old French colonists it is a rope
The real rope is 1,2m X 2,4m X 1,2m, or 3,62 cubic meters
but it is rare that it is sold like this in the details
it's more of a cord or a thin cord
it is 1,2mx 2,4mx 0,45m (or 0,40, or 0,30)
depending on the size of the pan
In general the price I give you is for 1,53 cubic meters of wood, good, Maple, oak, or beech. The trees are not as big as those in the south, they grow less quickly and are denser,
(For land measurements it is Arpents)
In general the stoves of the trade, the sheet is 1/4 is 6,32mm thick saves the top it is 8mm and the door is generally in cast iron with a ventilated glass a grooves to put a seal
There are several air inlet a primary a secondary to burn the gases, some have a catalytic converter in the chimney outlet.
qu, it is necessary to switch on only when the pan is hot
otherwise it gets dirty quite quickly, he sells the honeycomb to replace it occasionally.

To Andre,
If you have the opportunity, I am also interested in the details of the stove in
wood made from La Belle Province.
I lived there when I lived with my parents and we
heated exclusively with wood. At the time I was not interested
too much to that kind of detail.
I remember we had a big steel stove that
heated severely. So much so that the ash was often vitrified.
She was turning white and spanking puddles of glass.
managed to achieve this with the stoves from here.
Regarding consumption, it seems to me that it was less
than the one I had with the different stoves that I bought here.
That said, we often had chimney fires, but without
consequences the fireplace seems to have been planned for.

I noticed that here, it is easier to heat under -5c °
that between 5 and -4 ° C. Can be al less high humidity
outside .

Rabbit,
I don't know how you can make glass with wood. But if you insulate the fireplace well, dry wood and double combustion, you can exceed 1000 °. there, you better have a material designed for, because we are at the limits of the materials used for classic stoves.
For example, a guy from supra told me that in the lab they managed to obtain a blowtorch effect which perforated the cast iron plate at the bottom of the insert because it was too concentrated.
In a villa it would be a bit messy, wouldn't it?

It is not the wood that vitrifies, but the ashes.
But that's not really the point of the operation.

Hello Shutt
In my stove, I put fire bricks like the one we put in pockets of molten steel, the one that comes into contact with liquid steel, it is difficult to find thin bricks,
It is important to put a layer of ceramic wool insulation
between the sheet metal and the bricks, especially the one at the bottom, and arrange to support the bricks mechanically so as not to crush the insulating wool. The other top row of brick does not need insulation
The combustion air must be heated by the gases at the top of the stove, then it must descend slightly above the ash. (the cold combustion air cools the fireplace)
The heat must be at the maximum in the fireplace, so do not capture heat in this place, on the contrary well insulated.
The vertical construction of the stove is that once the fireplace is hot, we can stack several layers of poor quality wood that is not very dry, all the heat passes through this wood and dries it.
when he arrives at the foyer it's super dry,
The heat is only captured in the top plate just before returning to the chimney, it takes a little for the chimney to stay hot, otherwise when it is -20 it condenses and it flows in the chimney, at these outside temperatures all the chimney smokes white, it is water vapor that the wood contains
completely dry wood does not exist.
Moreover in my case the wood and outside in the snow pile, we avoid storing it in the house, when it is frozen well, the ants and the bugs are frozen, if you enter the house too early the bugs can wake up and you are right everywhere. So directly in the stove it dries on.
Another thing the first time you light a stove with new bricks, it has difficulty performing (the humidity in the bricks prevents the fireplace from reaching high temperatures) it takes 24 hours of heating to dry out the bricks and you must not make it work at full power the first time, once it's hot you can give it a slap, anyway a stove of this size you cannot open it at the back it is not liveable in the hut.
To light it, roll a newspaper into a ball and 4 logs of 2 to 3 inches in diameter arranged like an Indian tent, the door slightly open, once part close the sealed door and open the plugs of 6mm and it is all, an hour later two good logs.
The fault is when you suddenly open the door there is a little smoke that escapes, with the experience you open delicately
the door before reloading it, but like most of the time when you open the door there is nothing left but embers this is not a problem.
If you want the fireplace effect, the front door can be glass, there you see the wood (burning),
A slow combustion stove does not make a flame we just see red embers burning with a certain hissing sound

For what Rabbit says it is true sometimes it is -2 with humidity and we freeze at nothing else times it is -20 very dry and it does not appear
just the top of the ears if it is windy. When you heat with wood it is preferable to humidify the house or at least to control the humidity it is more comfortable.

To all,

If anyone is interested, I will add that this type of stove is reputed to have an efficiency of around 90%.
These plans are the work of André Philippot, from Sorel in Quebec. This study dates from the 70s, which shows the advance of Canadians in this area.
