To optimize underfloor heating (UFH), choosing the right flooring and underlay is crucial for thermal conductivity. Ideal choices include:
Tile/Stone + Thin-set Mortar: High thermal conductivity; maximum surface temperature of 29°C.
Engineered Wood + Low-TOG Underlay: Combines stability with efficient heat transfer.
LVT/Laminate + Specialist Heat-Transfer Underlay: Use dense underlays with a low TOG rating under 0.5.
Key considerations for UFH efficiency:
Low TOG Ratings: Ensure minimal total thermal resistance.
Avoid Thick Carpets: Keep combined TOG below 2.5 to prevent heat insulation.
Caution with Solid Wood: Not recommended due to potential warping.
No Extra Underlay: Avoid adding another underlay if the LVT already has one.
