GEBE-STREBEL GmbH

What GEBE-STREBEL GmbH does

GEBE-STREBEL GmbH is an Austrian privately held heating technology manufacturer headquartered in Wiener Neustadt, Lower Austria, with origins dating to a December 23, 1893 patent by Ing. Joseph STREBEL for a modular boiler with O-shaped elements. The company operates through two core subsidiaries, Strebelwerk GmbH and GEBE Gesellschaft m.b.H., under the Strebel, GEBE, and Thermostrom brand names, employing over 100 people across three Austrian production facilities and serving customers throughout Europe. Its product portfolio spans the full heating technology stack: cast iron section boilers built with proprietary GG-20 special cast iron and the in-house-developed Dreizugprinzip (three-pass principle), wood gasification boilers, pellet boilers, biomass boilers, solar thermal collectors and packages, heat pumps, buffer and hot water storage tanks, gas and oil condensing units, solid fuel boilers, and gas room heaters and cooking appliances.

The business operates a sales-led, channel-driven go-to-market: heating equipment is sold primarily through a certified installer partner network (Installateurpartner) in Austria, Germany, Switzerland, Spain, and the UK, with additional distribution into Central and Eastern Europe. Factory customer service (Werkskundendienst) provides commissioning, maintenance, and repairs at a published rate of EUR 160.80 per technician hour, creating a recurring service revenue layer on top of one-time equipment sales. Pricing for equipment is quote-based via published price lists; service pricing is transparently disclosed. The 1993 merger with the GEBE group brought gas-fired heating and cooking appliance capabilities into the portfolio and remains the most significant structural event in the company's modern history. The company has no disclosed external funding, no public listing, and operates as a privately held family-founded enterprise.

Core offering

GEBE-STREBEL GmbH manufactures and sells heating systems including cast iron section boilers, wood gasification boilers, pellet boilers, biomass boilers, gas and oil condensing boilers, solid fuel boilers, vacuum tube and flat plate solar collectors, hot water heat pumps, buffer and hot water storage tanks, and gas room heaters. Products are produced in three Austrian manufacturing facilities using proprietary GG-20 cast iron with the Dreizugprinzip (three-pass principle) and are sold through a network of installer partners alongside factory-direct customer service for commissioning, maintenance, and repair.

Product overview

GEBE-STREBEL GmbH is a traditional Austrian heating technology manufacturer with over 100 years of experience in boiler construction. The company offers a comprehensive portfolio of heating solutions including solar thermal systems (vacuum tube and flat plate collectors, solar packages), biomass boilers (wood gasification boilers Turbotec and TT Easy, pellet boilers Narvik, tht Nova, Varan, Biotec, and Biomatic biomass boiler), fossil fuel boilers (gas condensing units Victrix Extra, Zeus Superior, and PRO, gas/oil boilers, oil condensing EC-C), solid fuel boilers (Ökotec), heat pumps (Astral W for hot water), storage solutions (buffer and hot water tanks), and gas room heaters (external wall and chimney-connected models). The product range follows a modular approach where customers can combine solar systems with storage tanks and various boiler technologies for complete heating solutions. STREBEL products are manufactured using cast iron (GG-20) with the proprietary triple-pass principle for optimal efficiency, while GEBE focuses on gas heating and cooking appliances.

• Fröling Heizkessel- und Behälterbau: Austrian-headquartered manufacturer of biomass heating systems (pellet, wood chip, wood gasification) plus buffer tanks. Direct peer to STREBEL's biomass boiler portfolio with comparable installer-channel DACH focus.
• Wolf Heiz- und Energietechnik: German manufacturer of gas and oil condensing boilers, biomass, heat pumps, and solar thermal systems sold primarily through installers. Directly comparable product mix and channel approach to STREBEL.
• ETA Heiztechnik: Austrian manufacturer of wood-fired boilers, pellet boilers, and wood gasification systems plus heat pumps and solar thermal. Direct Austrian peer competing across STREBEL's biomass and renewable heating portfolio.

Broad incumbents

• Bosch Thermotechnology: Global heating and hot water division of Bosch offering residential and commercial boilers (Buderus, Junkers brands), heat pumps, and air conditioning. Overlaps STREBEL on boilers and heat pumps but operates at much larger scale with broader product and geographic portfolio.
• Buderus: Long-established German heating brand (now part of Bosch Thermotechnology) manufacturing cast-iron and steel boilers, gas/oil condensing units, heat pumps, and solar. Closely comparable on traditional boiler lines STREBEL competes in.

Emerging players

• Stiebel Eltron: German-headquartered heat pump, hot water, and renewable heating specialist. Increasingly relevant as European policy shifts from boilers toward heat pumps - directly competing with STREBEL's Astral W and forward product roadmap.
