Installing Underfloor Heating Under Laminate & Wood

There are two types of under laminate & wood heating systems


Ultra Thin

At under 2mm thick the ultra thin heating elements won’t add anymore height to your project


The entire process can be be done by a competent diyer the only qualified person needed is an electrician

Primary Heating

The heating elements are suitable as primary heat source. Providing the heating covers 70% of the area


No radiators

That’s right no more unsightly radiators taking up floor space. Giving you that added space

under laminate heating

Let's start at the begining

Living Heat has been selling electric underfloor heating in the UK for over 12 years. Today we now stock the largest range of electric under floor heating systems in the UK. We have also expanded into other countries and currently export our floor heating and insulation’s to 16 other countries. We offer free technical advice and pride ourselves on product knowledge and after sales service. If you have any questions or require assistance please just give us a call – we are here to help.

Product Feature

1: The sub-floor must be clean, sound and suitable for the chosen floor covering prior to laying the heating. Impact Plus 6mm insulation or hard insulation boards must then be installed over the sub-floor prior to fitting the heating.

2: Measure the floor accurately allowing for a 100mm+ unheated border around the perimeter of the area. Once measured make sure the heating mat is a suitable size for the area. The mat size and wattage can be found on the outer box and heating mat. The mat should also be tested for continuity and resistance at this stage. The readings should be noted down on the back warranty page of this manual.

NB; If the mat is incorrectly sized or the resistance readings do not match the test results on the box label, stop and return the mat for the correct size. Once the mat is unrolled it becomes the responsibility of the installer and the mat can not be returned for an alternate size.

3: Start the heating as close to the thermostat location as possible. If this is impractical the cold tail can be easily extended with a suitable electrical wire. Slowly unroll the mat using the foil tape to hold the mat in place. All exposed cables at the side of mats must be covered with the foil tape provided. As you proceed, the mat must be laid flat making sure the heating element is not twisted or stressed at any point.

4: To turn the mat in any direction or turn it back on itself the installer can cut through the mesh/foil backing, (DO NOT CUT THE HEATING CABLE) to allow the mat to be redirected in any direction.

5: Alternatively if the area to be covered is an irregular shape or an obstacle has to be avoided the mat can be cut several times into strips, (the cable must never be detached from its foil casing.) This will allow the thin strips of cable enveloped in the foil to be laid in any direction. The foil tape must then be used to cover any exposed wire and join all strips and mat runs together. Exposed wire can cause hot spots also disrupt the earthing continuity between heating sections. It is important that cables are not laid to close together. A minimum of 50mm should be maintained between cable runs. If the heating cables get too close, touch or overlap at any point the cable may overheat.

6: Once the heating is fitted the electrical resistance and continuity test should be repeated and noted down on the warranty page. Make sure these readings are the same as the readings noted down during stage 2. The heating should also be tested after the flooring has been fitted. There is no limit to how much the cable can be tested but to complete the warranty the heating must be tested before it is laid, after being laid and after the floor covering has been installed. All figures must be accurately recorded.

7: The floor probe supplied with the thermostat must now be fitted. The probe must be installed under the foil and between 2 heating wires but no more than 30mm away from one cable. Make sure when fitting the probe, no other heating or cooling sources can influence the floor probe such as hot water pipes. Once the probe is fitted a resistance check should be carried out to confirm the probe is fully functional and the readings noted down on the warranty card, When heating wood or laminate the floor covering manufactures recommended max floor temperature should be programed into the thermostat. The thermostat must also be set to regulate floor temperature, not air temperature.

8: If multiple mats are to be installed all mats can be connected together into a suitable junction box and then one suitable spur run to the thermostat location and left ready to be wired in.

9: The heating system must be run via a residual current device (RCD), fitted in accordance with all current electrical regulations at the time of installation. All electrical connections should be carried out by a qualified electrician. It is the installer/electrician’s responsibility to make sure the system is fitted correctly and any additional materials are suitable for use with the heating system installed.
