About EHS
Ernst Hörtnagl u. Söhne GmbH (EHS), based in Fulpmes in Tyrol, has been developing and producing flue, exhaust and stove pipes as well as heat-resistant pipe products for use in combustion installations and exhaust gas systems since 1974. Products are made from sheet steel, among other things with a material thickness of 2.0 mm, in computer-controlled, partially automated manufacturing processes with laser-welded seams. The product range includes product lines for room-air-independent (RLU) applications, pellet stoves, enamelled and thin-walled products, as well as bright steel and heat-resistant versions with coating. In addition to standard solutions, the company offers custom-made products and consulting. Production takes place at the site on the Fulpmes industrial estate, which was modernised in 2017 and expanded in 2022 with a new production line. 722 solar modules with a total output of 330 kWp are located on the company premises, covering about one third of the electricity demand.
