About Haas+Sohn
Haas+Sohn Ofentechnik GmbH is an Austrian family business based in Puch bei Hallein (Salzburg) that has been developing stove technology for residential use since 1854. The product range includes fireplace stoves, pellet stoves, kitchen stoves, water-fed stoves, chimney inserts, and DIY chimney sets. The welded steel stove body is offered with up to 60 months warranty; the cladding consists of heat storage concrete, natural stone (including Speckstein, quartzite, serpentinite), and safety glass. Technologies include the Easy Control single-hand air control, WLAN/App control for pellet stoves, water-fed systems with heat exchanger, and the patented stainless steel energy-saving draft regulator for chimneys and heating. In-house departments for prototype construction, a testing room with flue gas and fine dust measurement, a spare parts warehouse, and a central warehouse complement the development and sales. Sales are conducted through specialized trade and home and garden centers such as BAUHAUS, hagebau, HORNBACH, OBI, and OTTO in Austria, Germany, and Switzerland.
