Hi Emmanuel, I already had to ask you the question twice but without an answer from you:
-Is it you who did an internship at Sebasol and who aspired to set up your own business as a Sebasol installer?

Hi Bham,
Oops, I shouldn't have seen the messages ...
Yes, I did the Sébasol internship which I recommend warmly anyone who wants to design a solar thermal system (heating, hot water). A 12 hour training day but we really understand a lot.

On the other hand, I did not set myself up as Sebasol because in France, the market for solar self-construction is far too weak to live on.
Most self-builders make this choice to reduce costs or for the pleasure of construction, they are not ready to pay for a service or assistance ... In addition, self-construction no longer gives access to subsidies
(tax credit). It may change in a few years when the tax credit
will have stopped!

In the Jura, there is a Sebasol installer who helps self-builders but it seems to me that he only operates in his region ...

Yes, finally, the valve is an ultimate safety which does not correspond to normal operation (otherwise, it would be necessary to recharge the liquid circuit regularly).
Before the valve works, there will be the expansion tank which will compensate for overpressure due to high temperature.

I disagree...

The rate of solar cover does not only depend on climatic conditions, it also depends on the installed surface and the capacity to store heat.

On sanitary DHW, with our 70m² of panels (self-construction) and 60 m3 of buffer, we must be a few thousand% of coverage ... and we are in Belgium ...

Economically, I am 100% for self-construction ... it is normal that the subsidies do not take into account this kind of panels since they are there to inflate the prices of new gear ... not to reduce consumption fossils ...

Speaking of price, you who did the internship, for 20m² that would amount to approximately how much per m²? (without labor obviously ...)

Solar coverage rate = Annual energy available (storage included) provided by the solar installation / Energy consumed (not energy stored and stupidly wasted)

But you have the right to disagree 8)

I do not agree that you have to be in a tropical country to have a coverage rate of 100% ... not on the definition.

Capt_Maloche wrote:Energy consumed (not stored energy and stupidly wasted)


: Shock: Do you mean that the energy is wasted in a buffer?

It is certain that there are more losses in a 60 m3 buffer than a 400L tank ... nevertheless these losses are useful for indirectly "heating" the house since they remain for a large part "in the house "... Good ok we also heat the cellar (room next to the buffer at 20 ° C ... being optimized, I need an insulator for this ... will create a subject) .

There it starts to freeze all night and the heating floors have not yet been put into operation (taking from the buffer) ...

I know of few houses in the Ardennes which have not yet turned on their heating. Well let's be honest, we did 4 or 5 outbreaks in the stove since the beginning of September anyway :)

it seems to me that in the nordic countries there are more and more
autonomous dwellings (less than 3 kWh per year in energy)

which should give a coverage of 99, ...

for the moment I have not seen this approach in the countries further south
For example, I am in France, there are very very few

But, in the Paris region, for my part I did not turn on the heating either, just 4/5 outbreaks in 3 weeks

I just have a veranda and I open the French doors when I am present, i.e. The week ends.

It's currently 20 ° C in my house, cool isn't it?


Toff, do you have a reserve of 60m3? it is enormous!
Have you built a swimming pool in the basement?
