For eighty years, DEVI Electric Heating’s innovative solutions have been improving the quality of people’s lives by creating comfortable indoor environments.

Electric heating cable technology is also widely used for outdoor heating applications to minimise the hazards of snow, ice and frost and to ensure outdoor safety in winter.


DEVI Electric Heating is celebrating its 80th anniversary!

Established in Copenhagen, Denmark in 1942 as a manufacturer of heating elements for industrial purposes, DEVI Electric Heating has grown significantly over the years and is now Europe’s leading electric heating brand.

Electric heating products and solutions are applied almost everywhere and anywhere you can imagine. It is used in a wide range of applications; inside and outside residential houses, apartments and public buildings. In can also be found in infrastructure, sports fields and even in more specific areas ranging from trains to airports and roads. In 2003, DEVI Electric Heating joined the Danfoss family.

Why is electric heating a good answer to rising energy costs

As the world faces rising gas prices and potential supply disruption, electric heating powered by 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 strive to hit ambitious climate targets. These renewable energy sources will help significantly decrease CO2 emissions. 

When combined with modern, intelligent controls, electric heating can make grids smarter and facilitate renewable energy consumption. Also, 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 to help reduce emissions, increase energy efficiency in buildings, and ultimately enable countries to to meet their ambitious climate targets.

Electric heating is cost efficient solution

Electric underfloor heating in combination with solar PV is perceived to be 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, maximising 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 can achieve the required temperature quickly even though this varies a bit depending on the floor construction. What this means is that rooms can be heated only when required which therefore produces some amazing energy savings. The positioning of the source of heat under the floor and very precise thermostatic control ensure an exceptionally high level of energy utilisation, giving reduced energy consumption without compromising thermal comfort.

    Electric heating systems for the conservation of old castles

    The Örebro Castle is a medieval castle fortification situated in the scenic region of Närke, Sweden. The castle lies on an island by the river Svartån. The oldest part of the castle, a defence tower, was erected in the latter half of the 13th century, but its present appearance, the Örebro Castle, was constructed over the last century. Since 1935, the castle has been a national Swedish monument.

    Heating Mats

    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.
