All product datasheets are available for download on our Datasheets page. Here you will find technical specifications for heating mats, heating cables, thermostats and frost protection products.
Yes, multiple heating mats can be combined to provide good coverage in a room. However, all mats must always have the same power output per square metre (W/m²). It is recommended to install as few heating mats as possible. All electrical connections must be carried out by a qualified electrician.
Heatcom heating mats and heating cables work with most floor finishes including tiles, stone, vinyl, laminate, parquet and carpet. For wood, laminate and carpet, the floor temperature must be suitably limited using a thermostat with a floor sensor to prevent overheating. The thermal resistance of the combined floor finish must not exceed 0.125 m² K/W.
Yes, in well-insulated properties electric underfloor heating can be used as the primary heat source. Under good insulation conditions, Heatcom recommends 100 W/m² for primary room heating. For rooms with below average insulation or cool floor coverings such as tiles, a higher output may be required. A heat loss calculation is recommended to confirm the correct power output for your specific room.
The heating mat or cable can be laid by a competent installer, but all electrical connections to the mains must be carried out by a qualified electrician in accordance with national wiring legislation. The heating mat must be connected to the earthing system and supplied through a 30 mA HFI or HPFI residual current device. The installation must be documented at the electrical panel.
Heatcom offers a 25-year warranty on all embedded resistance heating cables and heating mats with a maximum power of 30 W/m cable and 200 W/m² for heating mats. AluMat has a 15-year warranty. Thermostats and products used outdoors that are not embedded have a 3-year warranty. Heatcom may provide longer warranty for specific installations.
Running costs depend on room size, insulation level, floor type and local electricity prices. A typical bathroom of 4-5 m² with 150 W/m² uses approximately 0.6-0.75 kWh per hour at full power. Using a programmable thermostat significantly reduces energy consumption by only heating when needed.

Heating mats are pre-spaced on a mesh and are ideal for regular shaped rooms such as bathrooms and kitchens — quick and easy to install on existing stable floors. Heating cables are loose and can be adapted to irregular layouts, specific spacing requirements or larger areas such as new build concrete floors. Both products are available in different power outputs to suit your insulation level and floor type.
We consistently strive to develop & build serious and long-term cooperative partnerships with our partners and suppliers.
