Hargassner
Heating Technology
of the future

We have been providing cosy warmth for four decades and would like to celebrate this significant milestone together with you. Numerous exciting surprises await you in 2024, stay tuned.

Hargassner is a family-run family business in the second generation. From Anton Sr. and Elisabeth Hargassner to their offspring Anton and Markus Hargassner – we are proud to be able to continue this tradition.

On the 16th of June 2023, the official groundbreaking ceremony for this new large-scale project took place at the headquarters of Hargassner Heiztechnik in Weng with (among others) LH Mag. Thomas Stelzer, BH Mag. Gerald Kronberger and BM Gerhard Wiesner.

Quick facts & data:

• 32,000 m² gross floor area
• The largest wooden multi-storey garage in Central Europe:
  13,500 m² of solid wood for 500 parking spaces
• 6,750 m² of office spaces made of wood over three storeys
• 500 m² apprentice workshop with its own training rooms
• Rental space for start-ups
• Planned completion: Autumn 2024

As of March 2023, the Polish industry leader for biomass boilers and heat pumps “HT Heiztechnik” was taken over as majority owner and integrated into the Hargassner Group.

The most important key points:

• HT Heiztechnik remains an independent company
• Brand identity remains as before
• 6,000 m² of state-of-the-art production area
• 150 qualified employees have been taken over 100

After only 8 months of construction, the extension of the office building was completed. In February 2023, five departments and the Hargassner management were able to move into the new premises.

• Addition of one storey
• 1,520 m² extension Total areahttps://www.hargassner.com/at-en/news/hargassner-integrates-ht-heiztechnik/
• 1,320 m² office space with meeting rooms
• 180 m² break area
• New total company area 75,000 m²

The Hargassner Energy World – multifunctional company centre and headquarters of the administration, training centre, exhibition area, adventure world and heart of the company catering – is being adapted to the healthy expansion of the company. In June 2022, work will begin on extending the office wing by one storey along the entire length of the south side. This project will create 65 new jobs.

We have rebuilt and created a completely new biomass world in our Hargassner Energy World.

Here you can not only learn about our heating technologies, but also about the world of biomass. The newly created biomass experience world aims to provide a deeper understanding of nature, biomass and heating with biomass.

The exhibition can also be visited on site at any time.

After 18 months of construction, the production expansion is completed.

• New production capacity increased from 15,000 boilers to 30,000 boilers.
• New premises of 54,000 square metres
• 8,000 square metres of assembly lines
• 6,000 square metres of offices and bistro for employees
• 95% of orders go to local companies
• Irrigation now through own rainwater canal

The extension of the production hall will start at the beginning of 2021. The Weng site will be expanded by 18,000 m². The production of boilers will be gradually increased to 30,000 per year.

The total area of the company will now reach a remarkable 54,000 m².

The Hargassner Group expands with the acquisition of the Polish company Rakoczy Stal.

The State Prize in the category “Environment, Climate and Energy” goes to Hargassner for the first time, for its product range of pellet, wood chips and wood log heating systems. We are incredibly proud to be part of the movement for environmentally friendly heating and renewable energy with our various boiler solutions. “Good for you, good for the climate.”

To further strengthen its presence in the alternative energy sector, Hargassner has acquired a stake in Thermosolar. This company is engaged in the development, production and distribution of innovative solar energy systems.

Hargassner takes over GILLES Energie- and Umwelttechnik in Gmunden, a company involved in the development and sale of pellet and woodchip boilers – in the 12kW to 160kW range – and in recent years has been increasingly and very successfully involved in industrial plant construction in the 180kW to 2,500kW range. The company has 60 employees and operates in several European countries. The focus of the integration is growth. The aim is to bring together the best of both companies. Hargassner’s managing directors, Markus and Anton Hargassner, describe the acquisition as an “important milestone for the further development of the company”, which will strengthen its position in the respective markets.

In production, a lightweight hall with an additional 1,200 pallet spaces is being built to meet the needs of the market.

The Hargassner Energy World will be inaugurated during the in-house exhibition from 7 to 9 June 2019.

More than 10,000 visitors will not miss this event and, together with the 300 employees, will enjoy an unforgettable weekend with one highlight after the other.

The Hargassner Energy World is being built. The groundbreaking ceremony on 23 November 2017 marks the start of the extension of the Hargassner company on an area of 6,000 m². With an investment of 10 million euros, the new training centre, a customer centre with an impressive biomass world and ultra-modern offices are being built.

Here you can get an insight into the Hargassner Energy-World.

Cultivation of the company’s own energy park on over 25,000 m². Here you will find poplars, willows, elephant grass, side grass and many other experimental plants. Here we test the suitability of various short-rotation woody crops for combustion. See Energy Forest for more details.

The ground-breaking ceremony for the new state-of-the-art logistics centre with a total area of 6,300 m²: 7 truck docks as well as a ground-level transshipment warehouse for picking 20 truck loads at a time are the cornerstones of this expansion. The total area of the company was approximately 30,000 m².

Opening of an annex with a dedicated gym for staff and a green roof terrace to relax and recharge. A new canteen and modern social rooms complete the picture of a vital oasis for employees. Construction of the new Research & Development Centre on a further 3,600 m².

Expansion with vision. Well equipped for the future! The final ground-breaking ceremony for the gigantic extension. 11,000 m² more production space, an employee vitality centre with its own gym are just some of the cornerstones of the new building.

Opening of Europe’s most modern biomass heating technology centre. Clearly recognisable from afar and architecturally expressive, the new Hargassner Heating Technology Experience World in Weng im Innkreis is absolutely unique and welcomes its visitors in a fascinating ambience.

In 2002, the ground-breaking ceremony took place for the new company premises, located directly on the main road in Weng. A completely new company building was constructed, with the first modern showroom, expanded production and a warehouse.

This was followed by the final expansion of operations at Gunderding. A new building provided space for a test and demonstration heating system, a fuel store and all the exhibition material. Further construction was no longer possible on this site. In the following years the idea of a new company location was born.

Only two years after the start, production figures showed that the first expansion of the company was imminent. An outbuilding was adapted, and the new production hall would suffice for the next few years. The next step came just 3 years later, when another production hall was added to the existing one, more than doubling the company’s floor space.

In the beginning, the Hargassner family only needed a small workshop to produce the required quantities. With increasing customer interest and the inexorable rise of the Hargassner name as a brand, it soon became clear: “We need more space!”.
