No I don't. If the heater is running it pulls enough to keep it from being a problem even with a family of 4 living here. In the last 35 years it hasn't been a problem for the most part. But now that I am trying to get rid of that heat and therefore the air draw I will have to do something long term. While my parents were alive my mother always tried to make it to Thanksgiving before lighting the heater and made it about 50% of the time. The house is so tight that it is necessary to open a window or a door to keep from back drafting the heater(or occasionally the water heater) With the heater running the house gets too hot on a good sunny winter day so opening doors or windows in later afternoon was common. So there was never a problem. Now I am trying to use the collector to add a bit of heat and more importantly take the excess to the basement to use the basement for additional thermal mass to reduce heating. But that means opening doors and windows less or not at all so I will have to do something. Current thinking is to add another collector coming in another existing crank open window to bring additional air and at the same time add an air to air heat exchanger and a heat bell to recover heat from the drier. Still mentally designing on that one. Coming up with a bunch of good window glass is the first step. Still trying to figure out how to implement the european style water ground loop HRV with it to. No heat pump but simply a large ground loop. The slope of the ground behind the house would be ideal for one aimed up to the west. Problem is that is completely away from the best places to put in the air exchangers. I know long term I have to do something and I am paying attention to it short term while I learn.

Have you considered aluminum screen?
It should be resistant to heat induced sag.
I see it affixed horizontally at the top with a strip of wood or metal furring,the screen fabric cut or folded to width, and affixed at the bottom as in a similar way.
With tension between the top and bottom, you might not need to affix the sides at all.
I have considered building a collector for my homes south side
With a first story of brick walls, I would need insulation.
Have you considered lining your collector with foil faced insulation boards?

2. Whole collector box cools off at night to outdoor temperatures. Minimal mass, sealed off from the house and a really good black body radiation surface virtually guarantees this right thru the glass. The very things that makes it a good absorber make it a good emitter too.

I love the design of having the collector completely covering the open window and sealing that in.
I had trouble understanding some of the wording of things. What does this part mean?

how is it sealed off from the house? and if it were, how would that make it more of an emitter of the house's heat, rather than less of an emitter? thanks
