Also, does anyone know what would be considered a "good"
difference in outlet water temperature? For testing purposes, If
I'm using water starting at 70F, what should I strive for? I plan
to use an indirect system with non-toxic anti-freeze, so, I shouldn't
be working with temps as low as 70F anyway but... I found 2
double paned sliding glass door panels today. I can build the
boxes and experiment with the 2 side by side until I come up with the
best combination but, at what temp should I begin to see diminishing
returns? Also, could I expect anti-freeze temps to be able pushed
higher than water alone? That's of course, provided that I can
attain temperatures that high anyway.
Thanks everyone,
Take care,
Ken
