I'm looking for a reliable source of copper fintube for DHW panels.
Does anyone here have experience with particular manufacturers and/or
products?

I built a prototype a while back; but used tubing salvaged from old
baseboard radiators - the tubing worked quite well but the landfill
had only a limited supply...

First thing Monday morning I'll visit Lowes, HD, and Menards - but I
hate to have to mark up their prices after incorporating the tubing
into a product. Also not sure they'll be prepared to deliver the stuff
configured (alloy, diameter, wall thickness, fin size and
bonding/spacing, length of finned section, length of unfinned ends)
the way I want it and/or in production quantities.

I found one producer (Fin Tube Products, in Wadsworth, OH) that looks
promising; but most of the rest I've identified appear to be targeting
high-end markets (power generation, chemical processing, etc) - and I
_really_ want to avoid the pitfalls of single-sourcing key components.

Thanks. I should have been more clear - the product I'm looking for
has transverse fins which are more efficient in my design. You can see
