What type of wood stove for house sandwich planks




by choupi_ced » 27/11/06, 16:06

Hello,

we are going to build a single storey house of 160 planks (40 of wood - 80 of extruded polystyrene insulation - 40 of wood) ditto for the roof. it will have a floor area of ​​124 m2.

we are interested in three types of stoves:
* the mass stove;
* the pellet stove;
* the Norwegian stove.

which seems best suited to our construction ??

thanks in advance.

I am not a specialist but I think that given the inertia of your building, the mass stove is oversized ... After you should ask a professional ... (a good one)

Between Norwegian and pellets it is more a question of life choice and budget (installation and use) than technological choice: pellets are more practical and it requires less work but it is also more expensive ... as much for investment as for use ... and it also consumes current ...

The mass stove, on the other hand, is perfectly suited for a wooden house. The power of a Nunnaunni, it is the one I own is only 6 kW but is well suited to my 50 m2 for the moment in traditional construction.

The fire diffuses its gentle heat for 24 hours after the last flame without any consumption of current.

I already have the fire, I am thinking of surrounding it soon with a wooden chalet.

Ok I didn't know that there were mass stoves as "little" powerful ... I thought it was 10 to 15kW minimum ...

in fact, with this kind of fire, one cannot really reason in the same way as with a traditional heating.

The heat is almost not diffused by convection, but only by radiation at a wavelength (it seems) close to that of solar radiation.

And indeed, the heat of this type of fire is absolutely inimitable, without any relation to another type of heating.

I know something about it, I am a heating engineer and install all kinds of systems. But none equal this one.

In addition, its combustion efficiency is excellent and the fumes are pyrolized at the top of the fireplace, which guarantees almost smoke-free operation.

As for security, it is excellent because we only make fires when we are present.

Frankly, my wife (a little skeptical at first) and I are delighted.


well with wood heating, we deserve its heating !!

In any case, congratulations for the site and the forum : Cheesy:

first of all thank you for these answers.

so let's give up the pellet stove.
several questions come to my mind:
* can a mass stove or a Norwegian stove alone heat my house? (or do they only heat the living room properly)?
* momotopo, what price should you count for a stove with a power of 6kw?
* would this power be enough for the surface of my house?

thanks in advance.

I did not know either that it existed in such a weak power but to bounce on your reflection above, it does the same thing as a tiled stove, Kacheloffen style, that we found and that we still find in Alsace, Germany, Austria, Switzerland, .....
I believe that what is necessary is to have a large mass which allows to have a significant thermal inertia, is not it?

I will try to answer the various questions asked, based on my own experience.
can a mass stove or a Norwegian stove alone heat my house? (or do they only heat the living room properly)?


it depends, in reality, you have to try to position the stove in a central position and "build the house around", if possible. The heat diffusing only or almost in the form of directly perceptible radiations, a simple partition will stop them. The builders estimate the possible heating distance to be around 6 to 7 m, the comfort distance being all the greater when the accommodation is well insulated. With us, the fire heats the entire 45 m2 ground floor, not the first floor which is never heated anyway, but the heat rises anyway after a while.

what price should you count for a stove with a power mass of 6kw?


I paid mine 4000 € 4 years ago, the aim being to burn reclaimed wood (pallets) in order to make it profitable. It's pretty much done today.
It's a lifestyle choice. The consumption of wood is 1% of the weight of the fire, in my case 12 kg of dry wood per day.

To my knowledge, there are only two manufacturers of this type of soapstone fire (soapstone) NUNNAUNNI and TULIKIVI which both have a website

http://www.nunnauuni.com/francais/
http://www.tulikivi.com/www/homeFRA.nsf ... t?OpenPage

I chose nunnauuni because the rates are more favorable for equal weight.
At the time, I bought the smallest 1200 kg, for the same price at Tulikivi, I only had 850 kg.

would this power be enough for the surface of my house?


I think we should take a little bigger anyway, the surface being a little larger.

Bham's question


It does the same thing as a tiled stove, Kacheloffen style, which we found and which we still find in Alsace, Germany, Austria, Switzerland, .....

yes absolutely, the principle is the same, unlike the stone used, which has nothing to do, the heat storage capacity of soapstone is exceptional.

If it is necessary to distribute the heat in distant rooms, the water remains sovereign, in particular in heated floors. This system also has the advantage of being able to add a solar system to it. Pellets have the advantage of regulation and automation compared to wood, but beware of the prices which have increased sharply.
Some automation is necessary to be able to go on vacation in winter ...

Hello,

in the case of a renovation stone country house, center of France, which I will isolate from the interior .. for a 1st floor, 4 room on 90 m2 .... including two of 30 you advise me what as stove I know nothing about it ... the ideal would be that it would be my main heating ... would like to do the same thing for the DRC ... maybe the heat will also rise up right?
Mass stoves are quite expensive ...
Thank you for your advice because I do not know much and it is true that we get lost a little ...
if you can help me and tell me about your experiences ..
please
