Electric Heating solutions for indoor comfort and outdoor safety

As the global supplier of electric indoor and outdoor heating solutions, we master advanced, heat-control technology that optimizes user comfort, safety and energy savings.

Why electric heating?

Electric heating wind

Electric heating a good answer to rising energy costs

As the world faces rising gas prices and supply uncertainty, electric heating powered by electricity from renewable energy sources is gaining importance as a valuable and sustainable heating option.

Indeed, demand for electricity is forecast to grow to 30% in 2030 and to reach 50% by 2050 as we make the transition to climate neutrality. By 2050, the European Commission is aiming for 84 percent of this demand to come from renewable energy sources which will significantly decrease CO2 emissions. 

When combined with modern, intelligent controls electric heating can make grids smarter and facilitate renewable energy consumption. And moreover, with the use of electric heating, no harmful substances are emitted to the air or to the soil.

Electric underfloor heating is a major opportunity for Europe. This can play a significant role in helping Europe reduce emissions, increase energy efficiency in buildings, and ultimately enable Europe to meet its ambitious climate targets.

Electric heating is cost efficient solution

Electric underfloor heating in combination with solar PV is perceived for the most cost-efficient heating solution when it comes to highly insulated residential buildings. Electric underfloor heating is also set to become cheaper for consumers than traditional gas, liquid and solid fuel technology.

Electric heating enables a comfortable room temperature with the lowest possible energy consumption. Room temperature can be reduced by 1 - 2 °C on average compared to traditional radiator heating, saving energy use and costs. 99% of the energy consumed by the electric underfloor heating is converted into heat, thus maximizing its energy efficiency and avoiding unnecessary energy losses by having to circulate water, for example.

Why is electric heating energy efficient?

An electric heating system achieves the required temperature quickly depending on the floor construction, so rooms can be heated only when required for amazing energy savings. Together, the positioning of the source of heat under the floor and very precise thermostatic control ensure an exceptionally high level of energy utilization efficiency, for reduced energy consumption without compromising thermal comfort.

Benefits of electric underfloor heating

A comfortable ambient temperature and quick response time are just a couple of the benefits electric heating offers. Learn more about these and other benefits of electric heating.

Electric heating applications



  • if (isSmallPicture) { Digital Thermostats; } else if (isBigColumns) { Digital Thermostats } else { Digital Thermostats }
    Digital Thermostats

    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.

  • if (isSmallPicture) { ; } else if (isBigColumns) { } else { }
    Indoor Thermostats

    The indoor thermostat is an integral component of the electric heating system, used to control the floor heating.
    Thermostats are electronic devices allowing precise control of the floor surface or air temperatures. They are equipped with air or/and underfloor temperature sensors control the heating element.

  • if (isSmallPicture) { Heating mats; } else if (isBigColumns) { Heating mats } else { Heating mats }
    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.

  • if (isSmallPicture) { Heating Cables; } else if (isBigColumns) { Heating Cables } else { Heating Cables }
    Heating Cables

    Heating cables are used for a variety of applications, including indoor comfort floor heating and total heating both for small houses as well as large commercial buildings.
    Heating cables are mostly used in connection with new building or larger renovation projects.





DEVI has consistently delivered value to customers through a commitment to quality, reliability, and innovation. Our products are supported by industry-leading assistance including the DEVIwarranty™.

It not only covers the replacement of cables or mats but also extends to the reimbursement of installation and material costs for up to 20 years!

Comprising five individual warranties, DEVI provides you with complete peace of mind when using Electric Heating products.
