copper pipe

I need to run about 50 ft of copper pipe for a solar hot water system. I need to push about 30 ft of pipe thru some joist bays..I dont have to drill.
Should I get 50 ft of coiled pipe or use straight.??I would want to push it thru under existing insulation....and then bend one end in an arc to get it outside and on its way to the panel.
At that point I will have to cut and solder. Or use a compression fitting.
I looked online for a story of how someone did it but there isnt much... any ideas??

I agree. I don't think you want copper in an area that will quickly radiate heat. I suspect the pex will have less conductive properties in terms of heat loss. I'm sure it will be cheaper than copper.

PEX is totally no go for SHW systems. The fluid can get to 200 F. It has to be metal.

Pex is rated for up to 200 degs at 80 psi.

But I agree I would stick to copper.
