Simple and efficient underfloor heating system
The UK government's commitment to achieving net zero greenhouse gas emissions by 2050, outlined in its Heat and Buildings Strategy (October 2021), necessitates a fundamental shift in how buildings are heated. This strategy targets significant emission reductions across 30 million homes and workplaces, with a focus on residential properties but also setting objectives for decarbonizing commercial buildings through minimum efficiency standards and performance-based energy ratings. A crucial component of meeting these ambitious targets involves transitioning to alternative heating systems, specifically high-efficiency electrical heating and heat pumps.
Underfloor heating is identified as an ideal complement to heat pumps because it can operate effectively at lower temperatures compared to traditional boilers and radiators while still delivering comfortable warmth. However, conventional underfloor heating systems, which typically utilize water pipes or electric mats, often present challenges in terms of installation and remediation, particularly in commercial settings. These issues include complex installation processes and difficulties in accessing heating elements for repairs.
To address these concerns, IOBAC UK Ltd, in collaboration with NexGen Heating, has developed Ezy-Warm Underfloor Heating. This innovative system is ultra-thin and designed for simplicity, capable of being powered by renewable energy sources such as solar panels. It employs far infrared radiant heating to maximize heat and cost efficiency. The Ezy-Warm system boasts straightforward installation, consisting of three primary layers: an Ezy-Warm Heated Mat, an approved underlay, and various floor covering options like carpet, Luxury Vinyl Tile, laminate, and wood.
One of the key advantages is that the system operates on less than 24V (AC or DC) power supply, eliminating the need for specialist electricians during installation. Furthermore, the floor covering can be easily lifted for repairs or to access the heating element. Performance tests indicate that Ezy-Warm uses 55% less power than conventional electric mats and incurs running costs 15% lower than mains gas (based on 2019 pricing). NexGen's expertise in developing heating films, leveraging patented graphite and graphene-based nanotechnology, contributes to the Ezy-Warm Heated Mats' exceptional heat-conducting properties and their ability to generate far infrared heat.
Far infrared underfloor heating functions by directly warming individuals and objects within a room, rather than inefficiently heating the entire air volume. The absorbed infrared energy transforms these objects into heat sources, which then gradually and evenly radiate warmth throughout the space, minimizing heat loss. This method significantly reduces ongoing energy costs compared to traditional convection heating. When combined with IOBAC’s adhesive-free magnetic flooring installation technology, Ezy-Warm becomes compatible with a broad range of floor coverings. Its use with IOBAC’s Ezy-Install Underlay allows for clean installation and easy uplift of floor tiles for repairs, access, or design modifications.
The material cost for Ezy-Warm Heated Mats is £32 per square meter (for 84% coverage), with an additional £14 per square meter for the power supply. The system offers several returns: lower installation costs due to its quicker and simpler process, requiring fewer materials and eliminating the need for professional plumbers or electricians. Its ultra-thin profile (0.6mm) also negates the need for door rectification due to raised floor height. Maintenance costs are negligible, as the system is maintenance-free and the heated mat is easily accessible for repairs without disruptive floor excavation. Lower energy costs are achieved through its energy-efficient ultra-thin profile, with independent testing demonstrating 15% lower running costs compared to mains gas boilers (2019 pricing) and a 64% reduction in carbon emissions. The product has received a Gold Award in the National Flooring Innovation Awards (Environmental category), was featured in Barratt Homes’ “Z House Project,” and included in Project Etopia’s demo home, earning recognition from the Solar Impulse Foundation and praise from industry experts for its innovative approach to heating without burning gas.
