This is ELCO
ELCO is a European provider of heating solutions headquartered in Hechingen, Germany. Founded in 1928 in Switzerland, the company belongs to the Ariston Group and offers heat pumps, solar thermal systems and gas condensing boilers for residential, commercial and industrial buildings. At the heart of the gas condensing boilers is the proprietary HEX³ stainless steel heat exchanger technology, whose multi-tube design supports condensing operation and, in selected product ranges, enables NOx emission values up to 60% below EU limits. The products follow a compact, modular design approach with cascade configurations; the floor-standing TRIGON® XL/XXL series are available with outputs from 160 kW to 2 MW and are suitable for hospitals, hotels, office buildings and other large installations. ELCO supports projects from new construction through renovation to modernisation and retrofit, and works with installers, consultants, architects and building owners. Since 2011, the company has implemented World-Class Manufacturing principles in its production sites and support functions.
