Thanks for your post @burnman and welcome to Workshop. I hope you get some great advice from our community members for this important project and many others in the future.
I have tagged one of our resident engineers @BIM_Engineer for you as he might be able to assist with some first steps.
Do you where the water problems have originated? Have they been addressed? It would obviously not be a good idea to replace the flooring without tackling the plumbing issues first. If you could provide a little more information I'm sure our members will be happy to assist in any way they can.
All the best,
Thanks for the photos at a glance I would say the underfloor heating has caused Condensation->Moisture-> Rotting floorboards?
All floorboards will need to be Removed, Dried & Salvage what you can, Then try timber salvage yards, insulate between the joists, put down a Damp proof Membrane
before you put the new floor down. Watch this video here
