As said before, start by providing a water circuit, with radiators and / or heated floors.
After which, you have the choice for the heat generator, and for the energies.
Personally I would tend to say solar + pellets, but that remains to be adapted to the case of each, according to the degree of automation required, and the possibilities of purchasing fuel.

Thank you very much for your answer ..
considering the old design of the house the water circuit and underfloor heating would be too expensive I think .... DRC maybe but in fact I have no idea of ​​the cost ??
without going through what are the other solutions ..
I thought I would put a stove down one above better insulate above, cha, manage the windows and go to the solar water heater ??
it's a bad idea ??

insulate, change the windows, yes, it should be done first. The required heating power will be reduced. And if you insulate VERY well, the heat has time to diffuse, and 1 stove may be enough for the whole house.
For heating, the cheapest solution is always the stove, both in terms of initial investment and fuel. Its disadvantages are cleaning and the obligation to feed. If you want to go on vacation, you have to plan for someone to come and make a fire in case of extreme cold. This is the "manual" solution.
There are stoves and wood-burning stoves that heat the solar tank, even this can be done "manually" : Wink:

It is up to you to see if you will have the time and the desire to take care of it every day. if you are not sure, plan that at least one of the 2 devices can operate in automatic mode. But there, it will no longer be wood logs.

thank you Philippe for your complete answer ...
I think to change the windows and insulate better because the only stone house ...
A stove below, a stove above ...
how to pass the heat from room to room ?? can we facilitate that ??
what would be in your opinion the budget in stove for each stove knowing that each floor is about 90 m2 and that the Second has more volume than the first ... Even better insulate the house will be less than a recent construction must therefore provide a little more powerful stove power ??
thank you for your precious advice

well, therein lies the defect in the distribution of heat by the air, precisely. Heat only passes from one room to another through the circulation of air. Count 2 ° of difference between the rooms when the air passes through the doors.
Some chimney inserts incorporate a hot air distribution system. Placed in a central position to limit the length of the flues, such a chimney will be able to heat the whole house. This would allow you to have a cheap, reliable and simplified system.
Please note: since the start of the year, stoves and inserts must have a yield of more than 70% to be eligible for the 50% tax credit.
As far as I am concerned, I consider that a welded envelope is required. It is the guarantee of a waterproof device in 20 years, while the joints of the cast iron assemblies will have cracked. In France, Deville has a few devices of this type, Supra is currently reviewing its copy to improve yields which were generally lower.
On the other hand, a hearth allowing logs of 55cm, will allow you to cut the wood only once in a stere instead of 2 times.
Randomly, I would say that you need in the 15kw, for the 2 levels.

I don't have the prices in mind, but it should be around 1500 € excluding taxes, plus the wind tunnel.

thanks Phillipe
in my case go through fireplace with insert would ask too much taf the fireplace is far from being centered and given the design of the house there would be too much to break ...
when you talk about 15 KW do you speak for the whole house?
what do you think to put a stove like:
http://www.flamme-bleue.com/prdt.php?c=22&s=90&p=390 placed in the kitchen
and another at the top which would heat 2 large terraced rooms 32 M2 each but therefore fills the high roof in the gable center at 4 meters + 2 rooms of 12 each with ceilings at 2,50
I would put it north side in the room of 32M2 which is a little below (less 1 M) compared to the others ..
what do you think

yes, 15kw, it was for the whole house.
Damage, you will then have to climb the wood and descend the ashes ...
Try to choose a double wall stove, like this one:
http://www.flamme-bleue.com/prdt.php?c=22&s=90&p=386
see the last line "Double-walled steel + cast iron hearth: longevity". The price is not higher, and in time you will be glad you paid attention to this little detail. when your neighbors have to replace the joints of the cast iron plate assemblies, you won't have to ask yourself the question.
With rooms so high, the heat will be up. provide a fan that returns this hot air down?
And I hope your kitchen is great, otherwise your wife will cook : Wink: To give you an idea of ​​the power of these stoves, a friend maintains a 150m² garage at 16 ° with a forest, even when it freezes, and without forcing.

Small note in passing.
isolate from the interior ...


Avoid at all costs unless you have a cellar that you can arrange
to sleep.

I made this mistake, I applied 5 cm of mortar composed of
artificial lime , rhine sand and polystirene balls
expense. Homemade recipe :P inspired by a marketed product.
The result was above all my hopes.
Super comfortable in winter, very low mark of my
consumption of wood, breathable, does not sound hollow when
l knock on the wall etc .. that happiness .Until summer heat.
This is where we tell ourselves that we have forgotten that it is not only winter.
30 to 40 ° c easy from home all from July to August. Hell!

We must think of a small detail, if we do not know how to evacuate the
heat produced from the house in summer, we have a big problem.
By heat producer there are the inhabitants, the tv and others
household appliances, lamps, pc etc ... The interest of having walls
in hard is that they allow to have a thermal inertia.
times the walls insulate from the inside we lose this famous thermal flywheel
and it’s already less comfortable.

Since I moved, from a house with thick thick walls
stone. I just cap the walls and enjoy
of this good doing freshness in summer and a temperature
very equal throughout the year. Loving the heat in winter, I
heats up to 25 ° c on average, using a wood stove
and an insert (which will be replaced by another cooker from 2
days ) .

Philip,

thank you for your advice and your link ...
for the kitchen it is 12 m2 but it is fully open to the dining room which is itself open to the living room ...
so it's ok for my wife :D and then I spend a lot of time also in the kitchen ... so it's good for me too ...
so the goal will be to distribute the heat well for the First floor ... I will plan I think a large room which will have 2 or 3 levels because the two rooms which are quoted on a different level I will provide at one point in my plans a place for hidden wood storage.

Rabbit,

I completely agree with you but you still have to insulate in one way or another that we only have stone walls ... if I heat as the house is done now I will have a hell of a heat loss that will s go outside ..
how do you do in your recent house?
me my walls are 60 cm in stone joined only in earth ...
a very ugly exterior crepit thick on 3 walls out of 4 but if I fire it I think the walls will come with ...
what do you recommend?
how is your house insulated ??

it is hot upstairs in the house in summer probably because of the roof which recovers heat but it is suportable

thanks for your advices

Personally, I insulated from the outside, with polystyrene plates and plastic plastering reinforced with a fiberglass mesh.
Indeed, the thermal inertia is there and we feel it well, and it insulates well.
drawback, the wall does not breathe, and not even at all. wetlands must be well ventilated, and I'm always afraid that the walls could rot. If I had to do it again, I would look for a product like Rabbit, but to apply outside, with fake stones around the windows and doors, to restore the original style which is erased in my home. : Cry:
You can take off your plaster, repoint the stones with mortar on 2 good cm, and your wall will not fall, even if it is raining. then put on whatever you want. Interior insulation is a horror for fixing furniture or paintings, that's why I opted for the exterior.
