What Ecotherm does
ECOTHERM Austria GmbH is a privately held, family-owned industrial manufacturer headquartered in Hartkirchen, Austria, that designs and builds stainless steel components and turnkey systems for hot water, steam, and solar thermal applications. The company traces its lineage to a blacksmith trade established in 1880 and has operated as a heat transfer specialist for over 50 years, producing high-capacity water heaters, heat exchangers, electric boilers, clean steam generators, solar thermal collectors, fibre-fleece insulated storage tanks, and pressure vessels. Its proprietary technology stack includes patented flat-tube heating coils and patented fibre-fleece insulation closure systems, an in-house R&D laboratory with thermal and aerodynamic test capabilities, and the ECOSIZE design software built on a database of more than 65,000 performance measurements.
ECOTHERM operates a sales-led, project-based business model: pricing is custom to each customer's specification and delivered on multi-year contracts under direct enterprise sales from the Austrian headquarters and a global franchise and partner network of 45+ countries. Revenue is generated through (i) stainless steel component sales, (ii) turnkey system design-build-install-maintain projects, (iii) OEM products and custom solutions, and (iv) training and consulting services through the ECOTHERM Academy. End-customers are concentrated in three verticals — Hotels & Hospitality (including Burj Khalifa, JW Marriott, Ritz Carlton, and Abraj Al Bait), Hospitals & Healthcare (Sidra Medical, multiple Gulf and European hospitals), and Industry & Manufacturing (L'Oreal, Continental AG, Heumann Pharma, Spitz Beverages) — with OEM and custom solutions as a secondary segment. The company is led by founder and CEO Eng. Herbert B. Bremstaller, has 101-250 employees, carries ISO 9001/14001/3834-2/EN 1090, ASME Sect. VIII Div. 1, Solar Keymark, and AD 2000 HP0 certifications, and in January 2026 began manufacturing its own heat pumps, completing its transition to a full-system provider across electric, gas, solar, and heat pump categories.
