Carpet

UFH can be used with almost all types of flooring, even carpet, providing that the carpet and underlay have a thermal resistance of less than 2.5 tog. Indications show that, for the majority of carpet styles, the thermal resistance will be less than 1 tog.

Stone, Ceramic, Slate and Terracotta

As these flooring materials have become more fashionable, there has been an increase in the number of homes using UFH. Heat-up time depends on the thickness of the tiles. Thick flagstones will take longer to reach optimum temperature, but once this is reached there's no difference in heat quality between thick or thinner floor surfaces.

Timber

UFH is suitable for use with many types of timber flooring, but most installers stipulate that the timber be specifically recommended for UFH use. The flooring should have a top temperature restriction (usually 27°C) and an expansion gap needs to be left around the edges (this is easily hidden by a skirting board or trim). Always liaise with the flooring supplier and heating installer before making your purchase. Many suppliers will recommend a specific brand of electric UFH and it's a good idea to listen to their advice.

Vinyls and Laminates

UFH can be used with high-quality vinyls and laminates. However, not all laminates or vinyls are compatible with UFH, so it's a good idea to check with the flooring manufacturer or the heating installer before committing. Many suppliers have developed their own UFH systems, or have one or two that they recommend.
