pecs with hot water baseboard

I plan to add a zone to my hot water baseboard system in the basement of my home (30X40). I would like to use PECS for all the runs to save money on copper (I can get tools from a friend), but I hear the PECS expands a lot. This would be long perimeter runs of up to 20ft or so before they hit a radiator. Can someone with experience tell me the right way to install this stuff and if there are any pitfalls? Thx, GT

No pitfalls with PEX

The expansion won't cause you any problems. We set PEX (stands for 'polyethylene' 'X (represents crosslinked)) in concrete and the expansion is contained by the concrete and there is still no ill effects. Knock yourself out.

Make sure to get the oxygen-barrier PEX or you will kill your system. Also check the temp and pressure rating and make sure you don't exceed either. I think it's rated for 200F at 100 psi. For standard hot water baseboard, you should be fine.
