On nothing because it does not yet exist! it was electric convector, a real wound what ...
So the whole installation is to be done.

Also the cheapest is to separate the DHW functions already functional with conserved electricity (good for the summer) and put the wood heating by forced air ducts as I have in one of my houses 60m2, much cheaper than the radiators and sufficient.
The energy to heat the house is much higher than that of domestic hot water and therefore the economy will be very important.
By keeping the convectors as a backup, it is also possible to ensure frost protection by prolonged absence.

After it is always possible to add a water pipe exchanger on the fumes that come out hot to heat a thermal mass and in addition the sanitary water which needs much less power than heating, and which therefore has no no need for a large balloon, 50L is enough given the power of wood heating, while the slow electric balloon requires much more, to keep for the summer, which later can become a solar heating in the summer cheap, like Forhorse did for his horse.

I tell you an economical solution in investment and free wood that works with me.

Furthermore I get lots of wood for free, logs and hedge trimming, in a quantity much greater than what I have been able to burn over 11 years of windfall since the storm of the end of 1999, so that the results are very interesting, free wood that heats and investment limited to basic insert and circulation ducts of air.
I see wood thrown in a recycling center or burnt in the open air, everywhere in France (smoked by my neighbors !!) both in the Var and in the Paris region, free wood perfect for heating !!

For 3 radiators the central heating is absurd.

While this solution is very economical.

It is on it is cleaner but the idea is still to use the log wood that I have in quantity on my land. With 5hectare of drill I use only dead wood and I still have rab then past that pelleted is not at all the idea ...

I will take a look at what is done in France in cooker thank you for the info.

As for the ball I wondered if I could not find a used one.
I really do not want to put more than 300L I find it quite sufficient

I understand your point of view but I had already thought about it and the idea did not appeal to me more than that.
First of all, the interior does not have false ceilings to hide the ducts, the roof is directly above us. It's very charming, all in wood of course and I can't see aluminum sheaths wandering around even in a formwork.

The idea was to make the most of the land resource which is wood and which we have much more than we need.
At the most it is therefore both DHW heating and cooking. In winter anyway.
With a 300L buffer tank of ocaz I can later install the solar.

The idea of ​​having radiators does not displease me, it is a heavier installation which takes a little longer to heat ok but at least the result is there, the heat is diffuse, pleasant and the radiators are still hot in the morning.

Having both, radiators in the main residence and hot air in the second residence, I prefer hot air with an insert, because it arrives in less than half an hour when arriving in cold weather (house at 5 ° C), whereas the radiators require more than one day to two days to heat the house when arriving cold house in my main residence !!

So in my opinion it is a false impression or idea, that the radiators are better.
The sheaths can be hidden behind a similar wooden formwork or passed in the attic above between wood and roof (with insulation then) as I currently have.
The price is also very lower.

If you have wood everywhere in your ceiling, have you considered the nature of the treatment of wood which can be very harmful, for sure especially if treated before the 2000s !!

I have this at home for the roof beams (smell) and I avoid any risk with strong natural ventilation of the roof and serious waterproofing of the ceiling !!
read carefully (cancers, allergies, diseases):

http://fr.wikipedia.org/wiki/Pentachloroph%C3%A9nol
http://fr.wikipedia.org/wiki/Traitement ... s_des_bois
People made sick without knowing it !!
http://la.maison.empoisonnee.pagesperso-orange.fr/

If you do not know, look for the dates of realization, if before 1990-2000, it is certain that the treatment is very harmful, and the current one after 2000 also remains it in principle less, but will be prohibited in the future !!
It is kafka, because if untreated the wood is eaten by insects and others and if treated, it is dangerous for insects and us too, and all living beings (especially pregnant women in the first months by a factor of 100 and more ).

Be wary of current treatments (even green) which could be discovered dangerous in the future as we have not stopped in the past to prohibit what was allowed before !!

300L is already a safety issue.
Then, to limit the number of ignitions to 1 / day and have a fire high enough for secondary combustion to take place, you can always add more if you feel the need. Not sure ...
In a well-designed and warm fireplace, this double combustion is already done at half speed. No need for a hellfire.

please, I know that it is more expensive, but think of heating the water in summer with the solar, therefore, buy a boiler with two possibilities of heating. (one for the stove, and one for the solar collector which will be installed later, it will be great.)

You are very right but these devices cost more because it assumes two coils in the balloon.
Do all the tanks have two heat exchangers? because one would be enough if we put T-valves?

Otherwise I find it on the net

http://www.leboncoin.fr/bricolage_jardi ... htm?ca=6_s

Is it impossible to use it? 50 euros is not expensive!
If we bring the water heated by the stove through the cold water inlet of the tank, where is the problem?
Notice to specialist

ps:
What do you think of that one?

Not as simple as that idea, I had done it, but with solenoid valves (which eat the current)
Not so simple, because in winter, you can have your boiler that heats with wood, and a radiant sun that heats too.

I repeat the question, pkoi not use a conventional balloon as DHW storage tank ????
