Indeed, sir, all valid points. I realized some of the flaws as I was building and testing it, but you sure do bring some smart cards to the table. This was really my first rad, (not to mention the first time I've ever soldered anything in my life), The tubing and T's cost ~$5- worth the investment for the experence. If I have time this weekend I may try something I've been playing around with in my head...
As for this rad, I realized even on paper it was a poor design. But it was/is intended to be put behind the rafters, exposing it to our chilly PA winter air... it's -8C out right now, and to give you an idea of how poorly it performs: my 1.2 T-bird is at 28C at the moment. But to get it behind the rafters it had to be >11in wide, >7in deep, and 16in tall to fit my hole in the wall....(the hole was very inexpensive).
The rest of the pics are
here....it's the first, but not the last.
Thanks for taking the time to explain a few things to me, Gerwin, I'll stop rambleing on in your thread now. I've bookmarked this for futher research....
thanks again!!
