How do I fix solid wood block flooring onto a concrete floor with underground floor heating?

Dear whistlecroft I don't recommend fixing solid wood floors on underfloor heating. If anyone says its ok to fit, do NOT let them fit the floor and ignore them. I would go for a semi solid (engineered) floor but must be 15mm thick or under.

We don't and also most manufacturers don't recommend fitting any type of solid floor thats going to be fitted over an underfloor heating system, the heat will cause numerous problems, Only engineered boards up to a maximum of 15 mm should really be laidover an underfloor heating system. Hope this helps! Jamie The London Wood Flooring Co.

Hi The most recommend on underfloor heating surface is tree-layered engineering floor (wood, ply, wood) layed floating system! You can lay also solid wood parquet (small blocks kind of mosaic) with to 12 mm thickness. This system needs to use two special two components adhesive.
