If you are running full temp heating (80/70C) I wouldn't put pipework in concrete as you could end up with cracking due to high temps. Low temp systems, plastic is okay but avoid any joints in the floor.
For long term use I'd go for copper. There are a number of plastic systems on the market but compatability is a problem with different jointing methods and even different pipe sizes. With copper there is no problem as pipework is all standardised. I've been making joints in 50 year old copper pipework no trouble. Wouldn't be able to do that with plastic!
