Electric underfloor heating for all types of floors

Electric heating is an energy-efficient and environmentally friendly floor heating solution. It is flexible for new build homes and renovations for both wet and dry installation.​

Quick-responding heating systems are easy to control. They enable great comfort and convenience with their user-friendly navigation providing long-lasting effects according to the highest-ranking quality standards.​

Electric heating can be utilized as comfort heating (as an additional heat source) or as the primary heat source.​

The electric floor heating system consists of three main components:​
• Heating element (cable, thin heating mat, or heating element for laminate floors, etc.)​
• A thermostat with air and/or underfloor temperature sensors.
• Accessories.

Floor type: ceramic tiles, natural stone or terrazzo floors

Floor type: ceramic tiles, natural stone or terrazzo floors

Ceramic tiles and marble floors, granite, and terrazzo are smart, easy to maintain, and almost indestructible. There are many advantages to choosing a stone floor. However, unheated stone floors are very uncomfortable.

On the other hand, cold stone floors can be combined with electric underfloor heating. Our heating cables or mats can be placed directly under the stone floor to help ensure warm feet and a comfortable temperature in the room.

Electric underfloor heating is suitable for stone floors as they lose heat quickly. However, such floors also heat up quickly when heating cables or mats are placed directly under the floor. This is accurately controlled by our advanced room thermostats. They not only control the heat precisely, they also ensure maximum energy efficiency. This ensures excellent comfort and economy. The comfort temperature of the floor depends on the floor covering. For tiles, stone, and terrazzo, this is 26 – 29°C.

Floor type: wooden parquet and laminates

Floor type: wooden parquet and laminates

Wood is a natural material which contracts or expands depending on the temperature. This creates demand for a floor heating system to distribute the heat in a gentle and controlled way.
 
The electronic thermostats with floor temperature sensors are the perfect choice for wooden floors. They ensure that the temperature in the floor construction is always in accordance with the tolerance level recommended by the manufacturer of the wooden floors.

Under all circumstances, it is important that the floor is well insulated underneath to ensure the best heating comfort and most economical result.

Floor type: wall-to-wall carpeting

Floor type: wall-to-wall carpeting

Wall-to-wall carpets (or fitted carpets) are warm by nature. However, a carpeted floor can still be advantageously heated using electrical underfloor heating. The heating cables or mats must be covered with a layer of tile mortar or self-leveling floor screed with a minimum thickness of 6 mm. This provides a good, even distribution of heat over the floor’s surface.

Carpets have a slight insulating effect on underfloor heating. This means that an underfloor heating system installed beneath a thick woolen carpet may take slightly longer to react to changes in the room’s temperature.
 
Choosing any type of floor covering, please consider the limitations provided by the floor supplier.​

    Heating Mats

    The heating mats are used for installation in a thin layer of tile adhesive, self-leveling mixture, or similar. The standard minimum thickness of the floor layer is 5-8 mm while the thickness of electric heating mat is 3–4.5 mm. This minimizes the floor level increase. Electric heating mats consist of a thin cable securely fixed on self-adhesive glass-fiber mesh, usually of 50 cm width. Thin heating mats are manufactured as ready-made heating sections with a specific area (i.e. 0.5, 1, 1.5 … 12 m²) including a power supply cable (cold lead) and hermetically sealed connections.
