What Flexel International does

Flexel International Ltd is a UK-based manufacturer of electric radiant heating systems, founded in 1978 and headquartered in Glenrothes, Fife, Scotland, where it operates its UK production facility. The company designs and builds carbon-based flexible heating elements and far infrared heating panels using proprietary printed conductive ink / carbon-film technology, and is self-described as the UK's longest-running far infrared heating element manufacturer. Its product portfolio spans underfloor heating (ECOFILM SET, ECOFLOOR mats, ECOFLEX cable, ECOFOIL aluminium mats), domestic and commercial infrared panels (ECOSUN S+, ECOSUN C+, ECOSUN TH, EcoSun U+, ECOSUN UB), specialised church and heritage heating solutions (ECOSUN CH pew heaters, ECOSUN K+, ECOFILM Raised Platform), outdoor ice/snow-melting systems, pipe freeze protection, mirror demister pads, and a controls range (V22 wireless thermostat, FlexelTouch, TH131 analogue).

Flexel is a wholly-owned subsidiary of the Czech-based Fenix Group, which the company cites as positioning it among the world's largest electric heating equipment manufacturers through shared European production capacity. The business sells primarily B2B/B2C hardware through a multi-tier UK distribution network — national and regional electrical wholesalers, builders merchants, plumbing/heating outlets, kitchen/bathroom/tile/flooring showrooms, online dealers and installation professionals — supplemented by direct e-commerce at flexel.co.uk and a dedicated trade portal at trade.flexel.co.uk. Pricing is on a per-unit, ex-VAT basis with a £10 flat delivery fee (free above £150 order value), and the company offers a free heating design service alongside product sales. Named end-customer case studies include St Augustine's Church in Dumbarton (heritage heating replacement) and PeachyKeen (vertical farming / hydroponic root-zone heating), illustrating niche specialisation in heritage buildings and controlled-environment agriculture alongside core residential and commercial/industrial segments.
