Yes I already knew the installation of Evrard, very simple but you have to obtain a higher "solar" temperature than with your underfloor heating for it to work, because the radiator has a smaller exchange surface.
I take note of the invitation.

Some info from a BYSUN interview on ChaleurTerre
While in some countries solar equipment is in supermarkets, we need in France, in addition to our already expensive conventional installation, contact a solar specialist and have him set up a second installation at often incredible prices.
Our equipment is taken directly from the factory. No intermediary will strike the sale price. The vacuum sensors come from China, the only country to mass produce this technology. China alone produces more than 95% of vacuum sensors. The rest of the material is generally of German origin. We have the same manufacturers on certain products
We are among those who believe that the current premium system prevents the emergence of solar in France. Buying a solar collector should be as trivial as putting curtains on windows. Why pass such an expensive test series, which is imposed on no other energy?

Hello everybody
I read your suite and again I saw my nickname and also two forums that I travel often
So actually we are quite numerous now to have made the choice of tubular that does not detract from the quality of the flat sensors.
Indeed, we are many to have sensors Bysun Pascall60 was one of the first with Andre bayle and then we made several grouped orders to control our shipping costs for those who did not live in the South East. Overall this is very good spend very little breakage and material compliant (only one problem on a solar station and on the resistance of a balloon.) But on the volume it is very low.
There were also two orders grouped by apper members (Yoda) and also some members who made purchases directly from China. There are therefore sensors from different manufacturers (sunpower, ....) there is even one of the compatibilities between certain tubes the KMax from Bysun and the group order from Yoda even if they are not from the same factory when closing the tube is made by a plastic stopper for Bysun and a cork stopper for Yoda. now (we know that we will not have too much difficulty for a re-supply we are very numerous and we know each other for a repair. André bayla even made comparative measurements between the two types of tubes, he hoped that the new tubes would be more efficient but this was not the case but the reverse, the results are on Apper.
the sensors offered by apper are 30 tubes and on Bysun it is 18 and 24 tubes there are also two other types at Bysun the UMax and the Smax which are more efficient than the KMax I have the three type of sensors now there is indeed a very big progress on the quality of manufacture on the last two sensors but they are more expensive
I am at your disposal for any information
Small information on the heating walls it would seem that the PER and the plaster are not very compatible (info Malogne APPER) so it is still preferred the cement as the floors.
If some of you already have solar installations it would be nice to make a presentation of installation on earth heat the more we will be more the solar will develop
http://www.chaleurterre.com/forum/viewforum.php?f=31&sid=727c463f29d17a6b6c5bec37e45272d4
And if it is an auto installation or auto construction you can also present it on APPER.
On Chaleur Terre we also talk about Econology of course
So all of your solar projects

Hi RV45
Super nice that you intervene on this forum
It is always interesting to have the point of view of a specialist in latest generation equipment, such as heat pipes for example
Our last question was about the difference in quality that could exist between "high-end" tubes and those offered by Apper. Life span and performance can be really different?
I also believe that the tube collectors would be well suited for use on existing central heating installations, which represents a majority of dwellings (excluding equipment in convectors)
Personally, I think solar is more likely to break through if we offer a boiler replacement / complement solution than if the only alternative is to break everything to redo a PCS.
Heat pumps to replace boilers sell well while the temperature of conventional radiators is often not suitable for this technology
Finally, heat pumps are not an "econological" solution because of the primary energy (nuclear reactor or fossil power plant with catastrophic efficiency) necessary for electricity production and its delivery to the user.
What do you think?

Hello,
For solar, the solution proposed by Apper with a reasonable cost is a good solution even if the performances are not necessarily comparable to the Viessmann that you quote. But when we do the cost performance this is correct especially if we have the necessary surface. We can always when the finances allow it to evolve towards more efficient sensors, at least we control the installation which is the main thing. But the best solution for solar will always be heated floors. I have a house over 100 years old and I remodeled in pc on the ground floor. I only have the kitchen to redo the floor I oversize my few radiators.
For the pacs the analysis that we offer is simply not good, because you judge the results not on the pacs which can have a cop of 5 like mine but on the production of electricity
.
I consider that the electricity that I consume is that produced by the wind turbines which are less than 20 km from my home
On the other hand, my neighbor who is on electric convectors I consider that he uses the coal thermal power station which is located 500 km in the north east of France.
Do you think which polu most
You can see that it is not totally objective, especially since I am between two nuclear power plants 50 km away.
No, the real truth is this:
http://www.pac.ch/dateien/La_PAC_en_10_questions1007F.pdf
For me there is not a solution but a set of solutions:
insulation, heat pump, wood, solar MOB ... It is obvious that heat pumps are an important part of the solution but not the only good obviously.
But what is most important is to act and act now.
I only hear people complaining that gas or fuel oil is very expensive. Well it is well done for them, they were warned and they did nothing and the longer they wait the more they will be in a difficult situation to do it.
I save more than 2000 € / year on my oil boiler solution. I have invested heavily for 4 years, but I have already paid off.
And I still have to do on my insulation and my heated floor.
So let's hurry up the price per barrel will be 200 € in a year and 300 € in two years and the first oil shortages are announced between 2010 and 2012 and this since July 2007.

Thank you RV 45 for these details
When I say that heat pumps are not economical, in reality, I should say:
Electricity production from the heat produced by a thermal or nuclear power plant is an aberration
Especially if the use of electricity is used to produce heat in a convector.
A heat pump is a great way to draw calories from a rather warm natural reserve (cold on a human scale)
It is true that the heat pump is not responsible for the energy choices of governments, which until now have been content to go for the easiest (petroleum and uranium)
Where electricity is produced by hydraulics or wind, the heat pump has its place (in addition to solar for example)
What I fear with the disproportionate development of the CAP as the only heating solution (economical?) Is once again, a lack of alternative to electrical production that we know
Solar energy will still fall behind if EDF justifies its investments in nuclear power to justify the ever-increasing demand. What will happen if tomorrow homes equipped with oil or gas, switch to a heat pump?
A+

It is also necessary that the people who are in pure electric also pass in pac to divide their electric consumption by 3 and at the same time that they insulate their housing and which installs solar.

solar
hi christophe, you brought up the subject, great, now i'm always walking around with my camera and when i see a solar or wind installation, i'm near machine-gunned.
by cons do not count on me to take pictures of heat pumps, or more commonly pump money (electric)
solar greetings to all.
tiigrou, ex / lux, ex / auv, but biker always.

Here for those interested, here is the house of our Tigger:
I am in the process of making a file of it:
https://www.econologie.com/pourquoi-choi ... -3773.html
Notice to others who want to present their home (ours as soon as we have performance all year round)
