Hello again to all
After the electricity problem, solved by the PV panels and a wind turbine (still in its box, waiting for the scrap mat)
After the water problem, which initially was to be solved by a well, followed by a drilling and finally resolved by a capture from a source at the neighbor ...
Here's the problem of hot water!
I already have an overlapping of 200l in perfect condition (new), of which only the metal hood is a bit battered (osef)
I intend to modify it to supply it with 24V with the surplus production of the wind turbine. that's for the winter ...
Now for the summer, I would like once more to the advantage of the sun ...
Several solutions are available to me and I hesitate:
- Either install commercial vacuum sensors (kind bricod ... to 270 € or 353 € depending on the number of tubes)
The advantage is that it is immediately ready, basically there has out of the box and do some plumbing.
And then install and scalable by adding a heat exchanger and antifreeze it can operate even in winter.
The disadvantage is likely to be too much power, even 9 configuration tubes. So I need to provide an efficient discharge loop (swing hot water in nature what) or partially hide the sensor, otherwise hello overheating.
- Or make a "home made" flat panel sensor. I don't really see any advantage. it's going to be long to do, as expensive and less efficient than a vacuum sensor. Ultimately the only advantage would be guaranteed longevity and the possibility of repairing itself even in the event of problems.
- Either use the tip of the black polyethylene tube placed simply on the roof. It is very inefficient but cheap and fast and certainly more than enough from May to September.
- Is ? something which I did not think ...
In your opinion, what is the best solution?
Knowing that in any case it will take me a circulator, and the management of the facility will be provided by the small PLC already in place (Crouzet Millenium II)
