Re: passive radiator design help needed
been looking into finned tubing, I haven't done a price request yet (afraid to ask).
The big issue might be bending as some of the types of finned tubing can't be bent at all, I believe helicoil can and there are some resistance welded carbon steel tubes that can, but I would prefer to stick to plain copper, or even aluminum.
on another note, I'm really dumb. Did the math again and I came out at 52 ft of tubing. Not sure where I got an extra 30 ft.
