Lower cost than that, you die:

on Wikistrike, a nice DIY:

I had the same idea of ​​recycling the fridge the other day at the recycling center ...

AMHA the best is the half-radiator: inexpensive, solid, etc.

Otherwise, an anthology of ideas:

Hello, here is a realization of solar panels with cans of coca https://www.youtube.com/watch?v=QLNViUsRCVU

in short some inexpensive and homemade solar hot water systems

slut,

small useful detail oli 80, the solar panels with cans are hot air, there is no liquid in it ...

Yes I think the same, if possible aluminum for lightness and non-corrosion ... provided you know how to assemble it (harder to weld aluminum than steel) ...

Hello,
I'm relaunching an old post on low cost solar collectors.
Indeed in my thermal storage project (high power). I am in the process of sizing my sensor surface. There eventually appears a need for around 100 m2 (on the ground).
My research aims to obtain a sensor that is simple to make and resistant, however, over time (hence the constraint).
I initially focused on the steel tank with copper, polystyrene insulation and 6mm polycarbonate plate .... 30 euros / m2 is too expensive.
I am now turning to polyethylene pipe associated with a sensor base, but which (not easy to reconcile the diffusivity of the different materials by performing a high-performance assembly (binder) to transmit the power of summer and winter. ..)
While passing to PE I possibly saw the possibility of associating PE with concrete (thin 1 or 2 cm) so as to have something solid in time .... The calculations show an inertia too penalizing in winter even for a thickness of one cm ....
So I leave in my research ..... currently a type of subject holds my attention EDPM.
This common and solid tarpaulin associated with PE (by hot coating and gluing) could provide an initial response ...

Copper is essential, go snooping around, you will see that it makes a very big difference.

This is also why I suggested in the other thread to put the drilling site close to the house, the heat does not like too much loss over long distances, everyone said, this is not is not good and it gets complicated! (big insulation of the conduit, etc) And we are looking for simple and efficient solutions right?
