A judicious question. This is the tank where the domestic hot water, the water heater, is stocked. Generally, it is equipped with an electrical resistance which heats the water with the current of night With the sun, it heats during the day ...

I am lucky enough to live in a large, secluded building. As it was necessary to redo everything, including the roof, I treated the whole south part in solar. There was no problem with the building permit.
A tip for the permit. On the plan, instead of meter "solar collectors", it is sometimes better to put "canopy on a slate gray background". It's better. I read it in a book 30 years ago ... But currently, solar is fashionable and there are certainly fewer problems.

Who can answer me?

What would be the disadvantage of the polyethylene "coils" (the current pipes for running water) black, rather than copper?
It seems to me that polyethylene is much cheaper ...

cordially
AJH

I think the polyethylene is too thick and too insulating so poor performance

Copper goes great for transmitting calories

A simple declaration of works, as for a fence, a garden shed, would suffice (conditional cautious), according to a heating engineer therefore no building permit. Unless the house is within the perimeter of a listed monument, church, old house, .... there it is not even worth thinking about.

Hi everyone...

I find the solar pane "home made" super, indeed, no need for advanced technology to achieve it.

Is there anyone who has experience in Switzerland? And that I might eventually meet?

Hi everyone on this super forum

I will make my sensors with brass plates of
2 mx 1m and 5mm thickness

12 8m diameter tubes 1m welded on the plate and spaced from 15 cm axis to axis and welded end to 8 x18 x18 tees and 18 tube then 18 or 20 output

My question is this because nobody talks about the dilation :(

Because the expansion of the plate is important in the trunk with the heat you made how the pipes of the outlets must not move well </ span>
And also after you 2m x 1m too large or not

<Span style = 'color: blue'> I found copper plates 2m x 1m x 0, 5mm </ span> to 51 </ span> euros HT too expensive or Not that says better

Thank you for your answers and congratulations to cuicui for your editing and help

good evening to all
