Zehnder Group UK: Driving low-carbon innovation in heating
Matt Broughton speaks to Zehnder Group UK Product Manager, ChrisWalley, about a landmark year of sustainable innovation, product launches, and the shift towards low-temperature heating systems.
year, combining strong growth with a strategic focus on sustainability and design-led innovation. Product Manager Chris Walley reflects on the company’s performance and the opportunities ahead. “2025 has been a positive and transformative
A
year for Zehnder UK,” Chris explains. “We’ve seen sustained growth across our portfolio, driven by increasing demand for low-carbon, energy-efficient heating solutions. Our design-led approach, coupled with technical expertise, has resonated particularly well as themarket transitions towards low-temperature heating.” Central to this success has been Zehnder’s collaborative efforts with distributors, showrooms, and installers, supported by enhanced technical advice and training tailored to new systems such as air source heat pumps. “We’ve also expanded our CPD and specification support for architects and consultants, helping bridge the gap between design ambition and technical performance,” says Chris.
A landmark product launch One of the standout moments of 2025 has been the introduction of Zehnder’s Aluminium Radiator range, which sets a new benchmark for sustainable, design-led heating. The collection features four distinct models - Kymaira,Myra, Symena, andOlympoz - crafted from lightweight, 100% recyclable aluminium. Designed to deliver fast, responsive
warmth, these radiators are optimised for low-temperature systems, making them ideal for spaces like bathrooms and kitchens where quick heat adjustment is key. “Beyond performance, the range embodies Zehnder’s
s 2025 draws to a close, Zehnder GroupUKhas marked a pivotal
commitment to elegant design, with clean lines, slim profiles and finishes that complement contemporary interiors,” Chris notes. All models are EN442 certified and comply fully with Part L building regulations.
Focus on low-temperature heating Throughout 2025, Zehnder’s overarching goal has been to support the UK’s transition to low water temperature heating systems, driven by stricter energy efficiency standards in Approved Document Part L. Heating accounts for around two-thirds of household energy consumption, making efficient, low-carbon solutions critical. Chris highlights that “radiators are exceptionally
well suited to low-temperature systems such as air source heat pumps, often outperforming alternatives like underfloor heating in comfort and responsiveness. Our low-temperature radiators deliver fast, effective warmth while supporting the shift to renewable energy.”
Next-generation immersion heaters Looking ahead to early 2026, Zehnder will launch two new immersion heater models: the IHC (Control) and IHD (Design). Both represent the latest evolution of Zehnder’s electronic platform, offering enhanced efficiency, safety and design integration. “The IHC model provides exceptional flexibility
with rotary dial, remote, or app-based control via Zehnder Connect, plus energy-saving features like programmable timers and replaceable control units for long-term use,” explains Chris. The IHD focuses on seamless design, featuring
a compact, colour-matched form with discreet electronics, intuitive operation via app or remote, adjustable surface temperatures, and a boost mode for quick heating.
Together, these complement the existing IHE
(Easy) model, completing a versatile immersion heater range tailored to private homes, hotels and multi-occupancy buildings.
Commitment to energy efficiency and sustainability “Energy efficiency underpins everything we do,” says Chris. “While low water temperatures can reduce heat output, improved building insulation balances this out. We engineer radiators to maintain consistent warmth, especially when paired with air source heat pumps or hybrid systems.” Electric models such as the Tetris radiator
enable independent room control, ideal for bathrooms and guest rooms, combining style with patented smart technology. Zehnder’s sustainability efforts extend across
design, materials and production. Laser welding on the Zehnder Charleston range reduces energy and water use while eliminating onsite flushing. Steel and aluminium radiators are produced with high recycled content and are fully recyclable at end of life. “We’re also addressing packaging, transitioning
to recyclable and recycled materials with a goal to eliminate unnecessary plastics,” Chris adds. Full transparency is provided via Environmental Product Declarations, CIBSE TM65 assessments, and Product Environmental Passports, supporting specifiers with real-world environmental data.
Looking ahead The coming year promises continued innovation, with new finishes and products designed to support low-temperature heating and energy efficiency.
“Radiators are just one part of Zehnder’s
holistic climate solutions,” Chris concludes. “Our portfolio also includes radiant ceiling panels, trench heating, and ventilation systems that improve indoor air quality and occupant wellbeing. Together, these technologies create comfortable, healthy and sustainable indoor environments.” With a strong foundation laid in 2025, Zehnder
Group UK is poised to remain a key player in the transition to sustainable heating, combining technical excellence with thoughtful design to meet the evolving needs of homeowners and professionals alike.
