Solar Thermal

It seems to me that the sections are very small. When you see a hot air heating duct, it is of the 400 to 500 cc type, often rigidly insulated.

I would of course put a fan (20-40 watts) controlled by a thermal probe. I still hesitate between a fan placed near the panels to reduce noise or near consumption to increase efficiency.

We must of course ask ourselves the question of seeing where to get the "fresh" air, the ideal seeming to me to be at the top of the room to be heated, the hot air outlet having to be at the bottom.

But, for my personal taste, I would have preferred a water panel, plugged into a radiator, possibly with a small circulator.

In fact it is true that I had thought of taking the air outside but indeed there would be a significant loss.
I have to improve this but my main problem is the power of the breath and the type of hose to use

I even think that the inside of the tube must be relatively smooth.

Hi bricolo07, everyone,

I answered you on un forum neighbor, I also think that your main concern is related to the too low flow.

Fi, the ugly AD44 who diverts the posters from forums econology!

sorry that this is misinterpreted, I didn't think there was competition or enmity between sites and forums .

To decrease the pressure losses it is much better, the disadvantage is that for the propagation of the noise of the fan it is very good too.
They sell "silencers" which are mounted on these pipes, chai not if it is valid and if it supports hot air?
