Hi there, I'm wanting to use underfloor heating as the main heat source in the room, and have been advised that I may need to increase to 200W per square metre. I notice all your mats are standard 150W. Also because it's an odd shaped room, I would probably use a loose wire instead of a mat. Can you confirm whether it's ok to increase heating to 200W per square metre on the tray please? And am I ok using a loose wire system? Thanks, Tim.


Hi Tim,

We do not know any recommendation about the heating mat to be at least 200W per square metre. It depends on many factors like type of the building, insulation etc.

Our mats have been supplied many times for a primary heating source.

We do supply a cable, please have a look: https://wetroomsdesign.co.uk/magnum-underfloor-heating-cable-1941-m#/130,thermostat,not-include/137,spacer-strips,not-include
