Hi bham
As long as the sensors are stopped, they are empty. When the sun begins to heat them (and there, more risk of frost), the regulation starts the circulator which makes the heat transfer fluid rise in the sensors, namely ordinary water which is in a small tank in the house, protected from frost.
When the circulator stops, the water being no longer pushed flows through the circulator and returns to the tank which empties the sensors which cannot therefore freeze.
The collectors heat the domestic hot water by an exchanger in stainless steel tubes, the equivalent of a coil, located in the beuler. When there is enough hot water, a valve sends the heat transfer fluid to another exchanger (with plates) which heats the water in the pool. I can also heat 8 recovery radiators. Unfortunately, I don't have a heated floor.
When there is no sun, a large fireplace (1,10 m log) unfortunately open hearth, with water collector connected to the same circuit, can take over. It is mainly used to incinerate the garbage that is preciously stored for days without sun! But we don't use it to heat the pool, it would be a waste.
I actually have an air purge at the top of the sensors, via a copper pipe which goes down into the house and which is connected to a valve, sometimes I want to put the sensors under pressure for a better efficiency of the circulator. But it's been a long time since this has happened, it works well like that, winter and summer.
I have no storage system (size and cost) other than the pool.
I suppose that in good weather, we recover around 500 Wh per m2 of collectors.
I live near Senones.

I actually have an air purge at the top of the sensors, via a copper pipe which goes down into the house and which is connected to a valve which I can close if I want to put the sensors under pressure for a better performance of the circulator. But it's been a long time since this has happened, it works well like that, winter and summer. The yield does not matter, with 40 m2 I have enough.
I have no storage system (size and cost) other than the swimming pool or the thickness of the sandstone walls of this old farm (exterior insulation on the north side with 12 cm of polystirene)
I suppose that in good weather, we recover around 500 Wh per m2 of collectors.

Thank you Ex-oceano, I will go to bed less stupid this evening. You also do service to those who like me wade a bit without daring to say it :( I'm going to end up figuring out how to post :P

Sorry, didn’t think I was more specific.

hi cuicui and thank you for your answer. Yes I could have clarified for the MP since I also went through this phase of learning on the forum (and that I don't know everything yet). Besides, I received yours and I send you an email in return.
For your installation, not only were you a pioneer but in addition you made an installation that seems both simple and very functional. And I read with interest that you don't have a heated floor, so solar also heats radiators, contrary to what everyone tells me, except to talk to me about heat convectors or oversized radiators.
I don't live very far from your house, 90/100 kms away. If it doesn't bother you I would come to see your installation. As long as I can't see, I find it hard to understand.

Hi Bham,
I hope you have received my response and the photo of my installation. Of course, 150 m2 of collectors (including 40 m2 of water collectors) is not trivial, but not much more expensive than tiles.
It was even less so at a time when the sun was not yet in fashion and made us pass for merry eccentric, even dangerous agitators: ph34r:. When I was talking about my "solar farm" I was suspected of being part of ... the sect of the Solar Temple! I even received calls from General Information! So, if you are called a sect, do not panic, I have seen others, the stupidity of some people is immeasurable and this should not prevent us from moving forward. Top hearts :P !
I roll 1/3 rapeseed oil at 79 cents from ED. Both green and cheaper, what more could you want? The engine is running flawless. with a smell of frying which I find nice. Too bad that filling the tank with 1 liter bottles is not very practical. I can't wait to sell it in 10 l can!
I haunt them forum of econology and gathers information with the project to manage to pantonize without fail my 205.
I would like to take this opportunity to salute André whose tasty Canadian speaking (ah! The accents, useless "fanfreluches"!) Spreads a refreshing current on our compassionate and agreed French language, and who does not stop experimenting and sharing generously with us the fruits of his labor.

A solar water heater is by definition one of the most rustic, African-style technology, with the cheapest materials possible. Seeking high yields with complex, expensive and fragile technology is an aberrant catch-catch. But as for the Pantone, it is advantageous to use stainless materials. My installation is all copper (soldering with tin) partly with recovered tubes.
The Beuler is made of stainless steel, expensive, I did not find any occasion '. Previously, I rusted 2 of ordinary steel :( , now I'm quiet :P .
