What Riello Burners does

Riello Burners (legal entity Riello Limited) is a UK-based designer and manufacturer of combustion equipment for heating and process applications, operating as a subsidiary of Carrier Global Corporation from its headquarters at The Ermine Centre, Ermine Business Park in Huntingdon, Cambridgeshire. The company produces gas burners, oil burners (light and heavy), dual fuel burners, and low NOx burners — including pre-mix and electronic cam variants — with a capacity range spanning 10kW to 30MW across residential, commercial/industrial, and process end markets. Its product line is supported by accessories (gas boosters, RWF 40/50 modulating equipment, acoustic shrouds), a structured spares business with documented part numbers and cross-references for older models, and CIBSE accredited training courses for specifiers and installers.

The firm sells on a quote-based model with no public list pricing, distributing through direct technical engagement with specifiers and installers in the UK and Ireland, supplemented by an industry-first online Burner Selector tool, BIM files, downloadable catalogues, and a returns/CRA process for parts. The company generates revenue from hardware sales (burners, spares, accessories), professional services (technical support, commissioning, warranty), and training services, with pricing configured to individual boiler requirements. Brand positioning emphasises over 100 years of design and manufacturing experience, a No. 1 market position in the UK and Ireland, and pioneering low emissions technology dating back to 1992.

Riello positions itself as the No. 1 burner supplier in UK and Ireland, citing marquee reference customers including the Leadenhall Building (the Cheesegrater), Liverpool Cathedral, Tate Gallery, DVLA, and Kings College. It maintains active memberships in OFTEC, ICOM, Gas Safe Register, IGEM, EHI, Eurofuel, and FPS, and continues to extend its product range — most recently via a new Process Burners Catalogue (2025), expanded monobloc burner range to 12MW, flue gas re-circulation burners, and CIBSE accredited CPD courses — while embedding its offering earlier into the digital specification workflow through BIM files and the Burner Selector.
