20mm Tekwarm Foiled 400 KPA UFH Board | 1200mm x 600mm | 150mm Centres for 12mm Pipe

Yes. This one's grooved for 12mm pipe at 150mm centres. It's the right pick if your manifold and pipe runs are already set up for 12mm, which comes up in smaller zones, utility rooms, or certain packaged kits. Running 16mm pipe? There's a version of this board for that too.

Same dimensions and core. 1200mm x 600mm x 20mm, 0.72 m² per board, 400 kPa EPS, foil face. The only difference is the groove is sized for 12mm pipe at 150mm centres rather than 16mm. Double-check your pipe diameter before ordering, especially on multi-zone projects where both sizes might be in play.

Yes, same requirement across the whole range. The foil face isn't a surface you can tile or lay flooring onto directly, so an overlay goes down first. Get that factored into your floor height calculation before you commit to the build-up, especially in retrofits where headroom is tight.

When your system is built around 12mm pipe. Smaller zones in a multi-zone project, single-room retrofits, or systems supplied as kits with 12mm throughout. At 150mm centres it performs well as a primary heat source in well-insulated rooms and doesn't need 16mm flow rates to hit a comfortable output. If you're not certain which pipe size applies, check the manifold spec first.

If your system is specced for 12mm pipe and your rooms need solid output, this is the one. The 16mm/150mm version (BM01924) suits systems running the more common 16mm pipe diameter. Both 150mm variants give you more heat per m² than the 200mm options, so if you haven't run a heat loss calculation, either 150mm board is the safer choice. Move to 200mm centres only if you're confident the room's heat demand is low enough to manage on the reduced output.
