ok, just spoken to a technical man at Ardex and he confirms the Ardex-Flex FS is suitable for underfloor heating (i saw a website somewhere that said an admix was needed - it's not). So for me Ardex-Flex FS and PCI Aquafug are now neck and neck in terms of specs (although i could do with some more opinions/reviews on the ardex one if anyone has any?!), so i guess i'll be buying whichever one i can get hold of easiest...
