Creating a central heating with wall heating

[Obamot]

... I'm not a specialist in that, you should ask a heating engineer (ok I'm going out ->)

Well, a priori I would say that's a very bad idea. If you do that you should then insulate the plasterboard from the wall with a real insulator (cellulose wadding), then who says heating thinks of expansion: the pipes do not have the same coef, I would say that we must forget (risk of cracks : night / day & seasonal cycle) or else you need a company that gives you a guarantee over twenty years ... (you can never be careful enough ... better than the famous prommesse that: "It will not arrive"...)

But certainly there are some who have better ideas than I do.

I found this link http://ecohabitat.wordpress.com/2005/08/18/murs-chauffants-2/

An extract :
"These walls can also be made of a formwork of two panels of thick and reinforced plasterboard (BA15mm). The boards are fixed on vertical wooden frame members. They are screwed with numerous 35mm plasterboard screws. , to withstand the thrust of the 2.50m high filling. This formwork is then filled from above with a mixture having an extended grain size: very fine sand to be coated, sand to be masonry, gravel, and pebbles. "

Thank you for your opinions, it will prevent me from making mistakes.

... no further comments. Make way for other opinions.

Yes, well, a risk of cracking in a plaster is still not dramatic, it is not a load-bearing wall. By dint of wanting zero risk we get locked into rules and standards and there is nothing we can do.

... yes then question "design" is the ponpon ... Why create conditions straight away or cracks will necessarily appear when it is enough NOT to meet said conditions from the start?

As for saying that cracks is harmless because it is not a load-bearing wall is nonsense. The most insidious heat losses occur precisely through the air which passes through the cracks of a construction. Not really possible to approve.

If we build in the event that we know that potentially cracks can appear in certain areas, the remedy is very simple:
— we put a joint (which is nothing other than a prefabricated crack).

The advantage of the seal is that the air does not pass !!!

PS: and that we do not come to say that it does not matter because a construction must "breathe". We know all that ... this is another very specific function: which is checked / calculated.. The air that surreptitiously circulates no.

But this is just one of many opinions.

It reminds me of the concept of the large, decorated earthenware stove, "German style (I say this because I saw it mostly in Germany, but it may not be the real origin), always placed against a wall separating 2 rooms, in order to heat them both.

Once hot, the stove radiates for a long time.

Making a wall like screeds for underfloor heating would be a good idea, but it is absolutely necessary to do it between 2 rooms, never to the outside: remember that an insulator does not prevent thermal conduction, it only delay ...

By the way, with an internal storage mass, it becomes really useful to have solar thermal collectors, because the mass can then store the heat for the night, or even for several days. Or a reserve of hot water ... 1m3 of water at 90 ° C is 93KWh of energy compared to a cold source at 10 ° C ...

Hello,
is would it be possible to return after 6 years?

Thank you for sharing
