A maximum floor surface temperature of 27°C should not be exceeded. This top temperature restriction is secured by using a thermostat which controls the heating system. Our thermostats are specifically designed for use with and to protect your flooring; automatically keeping your floor surface at a consistently safe and pleasant temperature.

You should also note that this maximum floor temperature means a certain maximum heat output so if you’re thinking of using underfloor heating as the sole source of heat, you should get a heat loss calculation done in order to ensure that underfloor heating meets the room heating requirement. If you need help with a heat loss calculation, our expert team is available to help you on 0345 345 2288.

Wood Flooring for Underfloor Heating

When choosing the wood or laminate flooring, it is important to ensure good thermal conductivity, which is best when using more dense wood. The thinner the flooring material and the higher the density, the shorter the heat-up time and more responsive the system will be.

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 is ideal. You should always check with your wood flooring supplier to check for suitability for use with underfloor heating.

Everything above the heater, including underlay, overlay and final floor finish need 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 the system if the limits below are not met. This may hinder the performance of the system and result in the system not working as desired.
