Low flow air solar walls

I have not read any posts about these Conservall (brand name) type of solar collectors.



I installed these (4 - 4'X16') units about 7 years ago, they each have a 8" duct with a active damper and duct fan that is controlled by a demand stat and a micro processor at the top of each panel that says that the panel is warm/hot enough to come on.



I was concerned about tight house problem with my ICF construction and need make up fresh air and this works great.



I like this concept and it works for me.

    good old days

    Saw many installations in Canada on industrial buildings in nineteen seventies. Difference between comfy and chilly is only a few degrees.

    SRCC is rating

    and certifying performance of air (transpired) collectors now. Some some actual performance and durability data is available. Looks like your brand is one of the listed.
