Underfloor heating kit with Vaillant 637?

[SomebodE]

I've just started the build of a rear house extension and would like there to be under floor heating connected to the existing Vaillant 637 system boiler with 470F weather compensator.

The floor will have 100mm PIR insulation and will have 65-75mm of screed on top so I'm looking to attach/clip the UFH pipes to the PIR insulation.

I know I'll need to swap out the VR65 control centre for a VR66 or VR61/62 and probably another room stat for the new zone.

The area is 4 metres by 9 metres approx.

Can someone recommend a UFH kit that I can use with this boiler?

I've seen kits from Prowarm and Poly Pipe so any feedback on these would also be helpful

I use polypipe, jg or nu-heat. But as Steve says all much of a muchness.
Check the guarantee lengths and terms and don't let a builder install it.

I've posted the installation as a job in case any of you are interested.

Croppie, please don't close the thread just yet in case anyone else has any additional nuggets of advice to offer on the kit selection.
