Digital controllers have the unique features allowing you to reduce energy waste. Some thermostats are fitted with Wi-Fi allowing remote control of heating systems via mobile application.

Heating mats are used for the installation of 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 minimises the floor level increase. Electric heating mats consist of a thin cable securely fixed on self-adhesive glass-fibre 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.
