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 Cable Technology

Over the last three decades Heat Mat have worked to continuously improved the design of their cables and mats to ensure their safety and longevity. This unique combination of technologies means you get a safe and fast to install system without sacrificing quality. Only Heat Mat’s systems include this combination of technologies:

• Litzer Wire Technology – multiple heating elements are spun together to provide superior strength in a very flexible heating wire
• 200°C Fluoropolymer Protection – super-high temperature fluoropolymer insulation surrounds the heating elements and provides superior protection against overheating and physical damage
• Kevlar Anti-stretch Cable – Kevlar strands run through the centre of the heating cable preventing it from being stretched and damaged during installation
• 100% Earth Shield – an aluminium safety shield wraps the entire heating cable to ensure the system is instantly shut down if damaged. The shield also enables the cables to hold their shape when being installed
• Anti-crush Cable Jacket – the high quality PVC cable jacket provides unrivalled protection against crushing and cutting damage during installation
• 100% Shielded Coldtail – the entire coldtail is shielded continuing the 100% electrical protection seen on our heating cable
