Well, PEX is cheap.

I've heard mixed horror stories though. Some people say how solar can get rediculously hot and melt through anything. Other people say that the hot water PEX works great, and why spend any more money on copper.

I need 25-30 feet each way between the collector and the solar tank, which will be in my utility room in the middle of the house. (No basement!)

1/2" soft copper is about $120. 3/4" is $180. I could buy a lot of connectors, valves, etc for that money.

I'm thinking of using PEX instead of copper if nobody has any objection.

Either way, I do want to use flexible material. It will make it a lot easier to work in my crawlspace that way. It's kinda hard to solder straight copper laying on my back in the dark!
