Hi,
I've got three solar h/w panels plumbed in parallel. They are almost level, and I have the feed and outlets going through T's of 1/2" copper.
I'm not getting any circulation through the first two panels, only the farthest panel cools down, (indicating water flowing through it)
I have an underpowered pump. Would a larger pump help or only make it worse, as far as balance goes.
I suspect the venturi effect is keeping the glycol pulled down instead of pressurizing the panel as I had hoped.
Could I use some sort of Y connection instead of the T's, or possibly step up to larger diameter tubing at the T to reduce the venturi effect?
Any ideas are much appreciated, Tom
