What ELCO Heating Solutions does

ELCO Heating Solutions is a UK-headquartered commercial heating brand operated by Ariston U.K. Ltd, a private limited company registered in England (company number 06414126) and part of the publicly listed Ariston Group on Euronext Milan. Founded in Switzerland in 1928 and present in the UK for over 35 years, ELCO manufactures and supplies commercial heating and hot water systems, including the AEROTOP air source heat pump family, the THISION and TRIGON condensing boiler ranges, VARION C-POWER combined heat and power units, instantaneous gas water heaters, calorifiers and buffer vessels. Its proprietary HEX³ heat exchanger geometry and water-cooled cold flame burner are positioned for class-leading low NOx and CO emissions, while VARION C-POWER is certified for 40% hydrogen blend operation.

The company sells primarily through a direct field-based sales force targeting specifiers, planners, architects, housing developers and public sector buyers, supplemented by a UK-wide network of trusted service partners for commissioning, maintenance and repair, plus an in-house spare parts operation stocking over £1 million of inventory with next-day delivery. Revenue derives from hardware sales of heating equipment, recurring service and maintenance contracts, and CIBSE-approved CPD training delivered through a West Midlands training facility opened in June 2023 and a hybrid-working UK headquarters in Brentwood, Essex established in 2024.

ELCO's product portfolio is positioned around commercial decarbonisation, offering hybrid configurations that combine gas boilers with heat pumps to support the transition of UK commercial buildings, housing developments and public sector estates towards net-zero. Its parent Ariston Group reported approximately €3.1 billion in 2023 revenue, operates in 40 countries with 29 production sites and 29 R&D centres, and recognised the group with an EcoVadis Silver Medal (top 15%, 88th percentile). ELCO itself has installed over 1.7 million heating systems across Europe and supports its specification channel with the award-winning Hybrid System Selector Tool.
