With the construction industry moving towards safer, smarter and more sustainable buildings, the sector must recognise heating systems' impact on the built environment.

Traditional fossil-fuel-based systems do not align with the UK Government’s aims for net-zero emissions by 2050. This poses a clear challenge to architects, specifiers and developers alike, who must explore sustainable heating alternatives.

In this article, we’ll explore how NBS Partner DEVI may offer the perfect solution with its safe, sustainable underfloor heating systems…

Electric underfloor heating (EUFH) is a compelling alternative to traditional fossil-fuel-based heating systems, offering 100% efficiency at the point of use and a host of other benefits such as cleaner indoor air quality and compatibility with renewable energy sources.

Unlike systems that rely on combustion or gas, electric heating produces zero on-site emissions and poses no risk of carbon monoxide leakage. With the UK government prioritising all-electric new builds and modern heat strategies, EUFH is no longer just a luxury—it’s becoming a mainstream, sustainable choice in both residential and commercial developments.

For anyone serious about sustainability throughout every aspect of a building, understanding the role of EUFH is paramount. DEVI, a Danfoss-owned brand with over 80 years of experience and a track record of innovation, offers tailored solutions designed to achieve smart, reliable, energy-efficient heating in any building…

Why specify EUFH?

With so much discussion focused on achieving net zero in a safe and sustainable way, EUFH offers an appealing pathway to more energy-efficient heating systems. For specifiers, DEVI systems provide exceptional energy efficiency and other advantages such as safety and intelligent controls.

Electric heating, by its very nature, converts nearly 100% of electrical input into usable heat. Unlike water-based systems that experience losses through pipes, pumps, or boilers, electric underfloor heating delivers warmth directly and immediately where needed.

This makes DEVI systems not only ideal for reducing operational costs but also perfectly suited to integration with renewable energy sources such as solar PV or wind. As more buildings seek to align with Part L compliance, EPC ratings, and BREEAM or LEED certifications, the synergy between EUFH and green energy solutions becomes increasingly vital.

Moreover, DEVI thermostats and sensors allow for fine-tuned energy management. Heating zones can be defined room by room, providing responsive, real-time control that prevents overheating and eliminates unnecessary consumption. These smart features contribute to lower utility bills and a reduced carbon footprint, without sacrificing comfort or performance.

When specifying for buildings, the safety and comfort of occupants must also be considered. One of the hidden advantages of electric underfloor heating is its quiet and clean operation. DEVI systems are entirely free of moving parts, fans, or combustion components, which means there’s no noise pollution and no risk of allergens or dust being circulated through the air – a crucial benefit for allergy sufferers or in environments such as healthcare facilities.

“Safety has always been at the heart of DEVI’s design philosophy. Our systems are built to meet the highest standards in electrical safety and longevity. Unlike traditional gas systems, there’s no risk of gas leaks, carbon monoxide exposure, or combustion-related hazards. This creates safer environments in both residential homes and public spaces such as schools, offices, and care facilities.”

Comfort vs total heating: which is right for your project?

To help specifiers choose the most appropriate underfloor system for their building, DEVI offers two core underfloor solutions: Comfort Heating and Total Heating.

Comfort Heating is designed as a supplementary system—ideal for bathrooms, kitchens, and entryways where cold tiles and surfaces often diminish comfort. By gently warming the floor surface, comfort heating enhances the user experience while allowing your primary heating source (e.g., central heating or heat pumps) to operate more efficiently.

Users can set precise schedules and, when paired with smart thermostats, ensure energy is only used when and where needed. This approach reduces energy waste and elevates comfort, making comfort heating a valuable addition to modern spaces.

Total Heating, on the other hand, functions as the primary heat source for an entire room or building. It’s a solution designed for full coverage, providing consistent warmth throughout without needing radiators or supplementary systems.

Combined with advanced programmable thermostats, Total Heating allows for complete control, enabling night-time temperature setbacks, unoccupied room settings, and energy-saving vacation modes. This helps users balance comfort and consumption, minimising energy use while maintaining a warm, inviting atmosphere.

Lasting reassurance through a leading warranty

Sustainability is about long-term performance, and DEVI stands behind the quality and durability of its products by providing a DEVIwarranty™ – a warranty package that covers five individual coverage areas, including product replacement, installation cost reimbursement, and material cost recovery for up to 20 years.

“The DEVIwarranty™ reflects our confidence in every cable, mat, and thermostat we produce, ensuring that clients and contractors alike can rely on DEVI for long-term performance with minimal risk.”

Build smarter and safer with DEVI and NBS

As the UK accelerates its transition to cleaner, safer buildings, heating must evolve in tandem. DEVI is proud to be at the forefront of this shift, offering innovative solutions that go beyond basic performance.
