Which Floors Can You Use With Underfloor Heating?


Underfloor heating is a wonderful and efficient heating system. However, the design of it means it's in close contact with the floor. Because of this, not every floor can be laid over underfloor heating.

It's fine to use engineered, laminate and luxury vinyl tiles, as these floors are all designed to cope with dramatic changes in temperature. However, it's always worth double checking with the product manufacturer, and remember that no floor should be exposed to temperatures above 27 degrees celsius.

Solid wood is not so suitable. The reasons you can’t use solid wood floors with underfloor heating is that the high heats can dry it out, causing it to shrink and creating gaps in the floor. When the heating goes off again, the wood reabsorbs moisture and expands, which can make it swell and buckle.

Unfortunately, our natural carpets are also not guaranteed against underfloor heating.


Hints & Tips


  • The heat needs to be spread evenly across the floor, with no hotspots.
  • Floors must be laid close to the subfloor, with no gaps between the layers so the floor doesn't dry out.
  • The relative humidity of the room should be less than 60% both during and after the installation.
  • Be aware that Beech and Maple floors react more dramatically to heat so will experience more movement than other species.
  • Our paper felt underlay has the lowest amount of thermal resistance. Thin foam underlays (2mm-3mm thick) can be used too but steer clear of fibreboard or thick acoustic underlays as these will reduce the efficiency of the underfloor heating system. Regardless of which underlay you choose, make sure it has a Damp Proof Membrane to cope with the moisture from changing temperatures.
