Flooring over underfloor heating in New Eltham
Most New Eltham UFH complaints come from the flooring, not the boiler. A 12mm plank with 3mm foam is doing the wrong job. We use 4–5mm LVT or 8mm UFH-rated laminate over ≤1.0 tog underlay so heat reaches 1930s bay-fronted semis with a scattering of post-war infill feet — not the subfloor.
