DEVI History

For more than 80 years, DEVI has been a pioneer in electric heating technology. Founded in Copenhagen in 1942 (as Dansk El-Varme Industri), DEVI’s first products were frost-protection cables for cold-storage.  

By the 1980s the company had grown across Scandinavia and Western Europe, and in 1987 it launched its own thermostats to become a complete systems supplier. Notable innovations followed: the thin DEVImat™ floor-heating mat in 1997 and the world’s first adaptive timer-thermostat (DEVIreg™550) in 1998. 

In 2003 DEVI joined the Danfoss Group, and continued to advance its technology – for example introducing touch-screen and mobile-app thermostats (DEVIreg™ Smart) in the 2010s. Throughout its journey, DEVI by Danfoss has “drawn on decades of expertise to deliver reliable products” – a legacy that builds trust with every new engineer and customer. 

Over the decades DEVI has overcome challenges from post-war rebuilding to modern energy transitions.  
In 2021 the company marked its 80th anniversary and moved its headquarters to Kolding, Denmark, cementing its heritage of quality and innovation.  

Today DEVI by Danfoss remains a global leader in heating, with an unwavering focus on quality and durability that stems from this rich history. Generations of DEVI employees and partners share stories of early installations and breakthroughs, forging an emotional connection to the brand.  

Looking forward, DEVI by Danfoss continues honoring its heritage – for example, ensuring 90% of products have Environmental Product Declarations by 2023 to meet new sustainability standards. 

“From icy glass cabins in Lapland to solar-powered homes in Germany — our systems quietly power comfort in places where excellence matters.” 
 

Real-world DEVI projects demonstrate tangible benefits: enhanced comfort, lower energy use, and greener operations. For example, staff members of a Northern Lights igloo village in Lapland report that DEVI by Danfoss underfloor heating keeps their 16 m² glass-roofed cabins cozy for guests, while remote scheduling tools let them shut off heat when empty – “ensuring average energy savings of 30 percent.” 
Guests love the warmth: “The place is amazing!… electric heating managed by remote control provides ultimate comfort,” according to project staff.  

Similarly, builders of a near-zero-energy housing complex in Koblenz, Germany chose DEVI floor heating for its quick warmth and ease of integration with solar panels. The DEVI system’s slim construction meant faster heat-up (under 30 minutes) and lower installation cost, and residents now use smart thermostats to optimize efficiency.  

In each case, installers and partners were equipped with DEVI knowledge (often via our webinars), ensuring the solutions were right-sized and efficient. 

These success stories highlight how DEVI empowers all stakeholders. Technicians trained through the DEVI-engineers can apply best practices to deliver smooth installations and energy savings. Building owners and end-users benefit from DEVI’s support and certification: for instance, learning modules show installers how to maximize return on investment and guest comfort.  
Across projects large and small, DEVI Academy has become the “behind-the-scenes” hero – providing on-demand training that turns product features into customer benefits. 

Innovation isn’t just what DEVI does — it’s who we are. For over 80 years, we’ve defined what electric heating can be. From the world’s first adaptive timer-thermostat to intelligent app-connected systems, we transform comfort into technology and turn energy savings into real-world impact. 

Innovation is at the heart of DEVI Electric heating. Our solutions exemplify smart, sustainable heating. Electric heating inherently converts nearly all consumed energy into warmth, and DEVI extends this with cutting-edge controls. For example, our systems seamlessly integrate with Wi-Fi thermostats and smartphone apps, giving installers the tools to schedule and monitor heating from anywhere.  

In 2016 we launched the DEVIreg™ Smart app, allowing users to adjust thermostats remotely – a game-changer for energy management. Under the hood, advanced floor-sensor algorithms and multi-zone control ensure comfort while avoiding waste. 

DEVI’s technical innovations meet the latest environmental standards. Combined with renewables, our products enable entirely green buildings: solar PV and DEVI underfloor heating form an ideal system that can run on 100% renewable power. 

Our training covers these developments: DEVI Academy courses teach how digital tools and connected heating meet building codes and efficiency targets. We also continually update content to include new product releases (like smart thermostats and cloud connectivity) and international energy standards.  

In short, DEVI Academy translates complex technology into practical know-how. Installers learn the “why” behind features – for instance, how adaptive algorithms maximize comfort – making the innovation both understandable and inspiring 

Behind every DEVI innovation is a passionate person.  

Our team members – from production engineers to C-level managers – bring DEVI’s story to life. They truly “draw on decades of expertise” in their daily work. For example, one Academy lead trainer, Alexander, started as an electrician in the 2000s and built snow-melting systems before joining DEVI. His hands-on background makes him a trusted mentor to new installers. Similarly, Krzysztof, a DEVI design engineer, fell in love with sustainable tech while studying renewable energy; he now incorporates eco-friendly features in every new product. Their colleagues span generations and cultures, but all share a commitment to quality and customer success. 

These personal journeys connect DEVI to customers. Sales expert Matteo might travel to teach DEVIreg™ thermostat courses in Spanish-speaking markets, reflecting our global reach. Technical Literature Specialist Alevtina, originally from Ukraine, develops multilingual tech-learning content so technicians worldwide can learn in their native language. Natalia provides high-level customer support in procurement so our Installers worldwide can easily receive any of our DEVIreg™ thermostats, cable or mat to experience the innovative features and easy installation. Each story – from the inventor of DEVImat™ to the mastermind  who created the DEVI Website  – adds warmth to the brand. 

By highlighting their motivations (engineering comfort, reducing energy waste, etc.), we make DEVI relatable. Indeed, as one longtime employee puts it: “I joined DEVI because I believe in a future powered by clean heating”. These real voices, combined with our proven track record, show that DEVI is built and run by people who care.
