Underfloor Heating for Wooden and Laminate Floors

hybrid

Both electric and water underfloor heating are compatible with laminate or wooden flooring. Generally speaking, electric systems are more popular with renovations and small to medium-sized rooms whereas water products are more popular in new builds and large areas.

Laminate and wooden floor surface temperatures should not exceed 27°C. This top temperature restriction is secured by using a thermostat which controls the heating system. If you are thinking of using floor heating as the sole/primary source of heat, get a heat calculation done to ensure that the floor heater will meet your heating requirement for the room.

Electric heating mats and foil heaters

The most used radiant floor heating system for wood and laminate floors is the Foil Heater. However, the best system for your project depends on the size of the room, floor height and many other factors. To help with deciding which system to choose, read our Buying Guide or contact us.

Thermal Conductivity

When choosing the wooden or laminate flooring ensure that the material is as dense as possible for good thermal conductivity. The denser the wood, the better it transfers heat. Also, the thinner the flooring material and the higher the density, the shorter the heat-up time and more responsive the underfloor system will be.

Both laminate and solid wood flooring make a good floor covering to go with underfloor heating as long as the wood is not overly thick. We recommend that wood or laminate thickness should be no more than 18mm as any thicker than this will hinder the efficient performance of the system. When it comes to the board width, wider boards will often show more “movement” than more narrow boards of the same material, so we recommend that the ratio of thickness to width should be in the region of 7 to 11. A board with a thickness of 16mm and width of 160mm would give a ratio of 10, so it is ideal.

Floor heating is generally compatible with also other types of wooden floorboards such as engineered wood. It is always good to double check with the flooring supplier the floor covering’s suitability for use with underfloor heating.

Installation of underfloor heating with wooden or laminate floors

Installation of underfloor heating is dependent on the type of system. Foil Heater being a popular system with underfloor heating the installation will include;

  • The type of underfloor heating
  • Underlay
  • Overlay
  • Fitting the final floor covering

It is good to note that everything above the heater, including underlay, overlay, and final floor finish needs to be in the limits set in the table below.

If the manufacturer of the wood flooring states that it must be used in conjunction with an underlay, the underlay must be no more than 3mm – 6mm thick and breathable.

When using the system with wood flooring, care should be taken to ensure effective performance of the system and we do not recommend installing a floor heater if the limits below are not met. This may hinder the performance of the system and result in the system not working as desired.
