Universal Underfloor Heating Cable
Flexible, ultra-thin 3mm underfloor heating cable
A flexible simple to fit heating system designed to provide energy efficient floor warming or a full heating system as desired. This electric underfloor heating cable is particularly suited to small or complicated areas where heating mats can be more complicated to install.
The systems output is varied by altering the spacing of the heating cable, allowing 200W/m2 to be installed in conservatories and similar high heat loss areas. An additional benefit of this system is that it can be used beneath virtually any floor covering if covered with a levelling compound and installed with an output of no more than 160W/m2.
- When installed at 200W/m2 this system is suitable for providing a full room heating system, even in high heat loss areas such as conservatories
- Perfect for floor warming or room heating in standard rooms when installed at 160W/m2
- Alter the heat output to match your individual requirements - outputs from 80W/m2 to 230W/m2 are possible
- When used with Heat Mat's intelligent thermostat timers this heating cable provides a more energy efficient and cost effective heating system than lower powered alternatives
- Particularly economic to purchase, and can be installed onto thermal insulation boards to provide a faster reacting and more economic heating system
- Significantly quicker to install than some alternative systems as there is no need to cover the entire heating cable with masking tape due to its high strength outer insulation
Selecting the correct heating cables
To start with you will need to decide on the heat output of your heating system. For floor warming or room heating in well insulated areas we suggest installing the cable at roughly 150W/m2, and for high heat loss areas, or for a faster reacting system, we recommend choosing a 200W/m2 output.
Once you have chosen your desired output you should measure your room to find the total floor area. You should then subtract from this figure any areas where kitchen or bathroom furniture will be placed, or where furniture without an air gap underneath it will be positioned. Once you have subtracted these areas you have your free floor area (FFA). If you multiply the FFA by the Wattage output you have chosen you will have the total output of heating cable you require, and you should then choose the most suitable combination of heating cables from the front of this sheet to provide you with the closest combined Wattage to your required output.
Combining multiple units
Undertile heating cables are designed to be laid together with other heating cables to ensure the perfect floor coverage. The cables are wired into the thermostat or junction box in parallel, and heating cables can be used to 'fill in the gaps' in a heating mat system, as long as they are laid at the same output as the mats.
Flexible and quick installation
Heat Mat electric undertile heating cables are incredibly simple to install, and in small or complicated areas can be significantly quicker to install than heating mats. The cable spacing can be altered to match your exact heat output requirements, and the system is fixed to the floor with the supplied high strength double-sided tape before tiling on top.
Sub-floor surfaces and insulation board
For the most energy efficient system and the fastest warm up time we recommend laying heating cables onto Heat Mat thermal insulation board. Heating cables can also be laid onto pre-primed concrete, tile or stone surfaces or suitably secured ply board.
Suitable for nearly any floor covering
If you are unsure of the final floor covering, the heating cables can be laid at an output of up to 160W/m2 and covered with flexible levelling compound. This allows nearly any floor covering to be laid on top including tiles, stone, carpet,laminate, solid wood, Karndean and vinyl.
Approved and guaranteed
Heat Mat's electric underfloor heating cables are independently BEAB and Semko approved, manufactured in Denmark in our BEAB approved factory, and supplied with a Lifetime Warranty. They are also certified by Semko as having a very low EMC radiation, which is a result of their twin conductor design and 100% aluminium earth shield.

Heating cables must always be controlled by a suitable electric underfloor heating thermostat with floor temperature limitation. Heat Mat thermostats are rated to 16 Amps, and if a system exceeds this loading a suitably rated contactor should be used. The circuit must be protected by a 30mA RCD and suitably rated fuse or circuit breaker.
