Heating Mats

Most floor finishes are suitable for use with underfloor heating, provided the floor has been prepared correctly and any manufacturer’s temperature guidelines have been followed. With finishes, such as wood laminates and carpets, it is essential that the heating mat is completely covered with a suitable floor leveling compound before the specified finish is applied. 

Moreover, for flooring, such as laminate, wooden parquet or carpet, we recommend DEVIdry™ / ECdry solutions as well as the use of a thermostat/regulator with a floor sensor. 

The heating mat is designed to be laid directly onto an existing floor surface, so it does not require insulation. However, if there is room within the floor to add insulation or a tile-backer board, we strongly recommend this as it will enhance performance and reduce operating costs. Please contact us in Electric heating for information. 

CONTACT YOUR ELECTRICIAN. Fuses can blow or circuit breakers can trip on either short circuit or overload, short circuit being the most common cause 

No, the electric heating mat cannot be shortened as this will alter the resistance of the element, which may lead to overheating. It is therefore important that the area to be heated is measured accurately (free floor area only) and that you select the closest smaller area element. Please feel to ask DEVI service for help. Mesh can be cut, but take care to not cut or damage a cable. 

The mat has an adhesive backing; if the floor is dusty or greasy, it will not stick particularly well. Priming the floor will significantly help the mat to fully adhere to the floor surface. 

The cold tails/leads have to be brought out of the floor and have to be connected in parallel, e.g., core colors connected together, brown with brown, blue with blue, etc. into a thermostat. 

The underlay that is usually supplied with wood laminate is an acoustic about 2-3mm thick; this is acceptable. If you are installing anything else, please call our technical team for advice. 

For laminate, we recommend DEVIdry™ / ECdry solution. 

We in electric heating do not recommend that the heating mat is installed under any such fixtures for a number of reasons. For example, it can inhibit the heat being produced from the system; and, if ever a fault was to occur, it would be extremely difficult to carry out a repair. 

We strongly recommend that each section of floor with a different covering has its own ‘mat’ as well as thermostat since each floor surface has a different maximum temperature limit. We advise to use a thermostat with a floor heating sensor. 

Contact our local office to discuss the best options for this floor. 

The actual width of the mat is 480 mm, but it is recommended that it be laid at 500 mm intervals to ensure the correct gap between runs is achieved. 

The difference between the two mats is the cold tail/lead (connection to thermostat). 

The twin conductor mat does not have a second connection tail/cable to return to the thermostat. The single conductor mat has a single “cold tail” at each end of the mat, and they have to be brought back together at the connection point. 

This is the connection at the end of the twin conductor mat where the heating element is connected to the neutral return. This is manufactured within the cable.
