Sommerauer achieves 47 official TÜV SÜD world records for dust and efficiency and 1 official GUINNESS world  record for highest energy efficiency worldwide

Hybrid biomass boiler ECOS achieves 23 dust world records (up to 0.2 mg/MJ) and 24 efficiency world records (up to 98% conventional, up to 110.4% condensing) in TÜV Süd boiler tests, which have been proven by TÜV SÜD test reports and international market analysis reports. In the meantime, 10 patents (European and other countries) with 84 invention variants have been granted by the patent office for the ECOS technology. With a newly developed artificial intelligence (AI) LOOP+, the boiler functionalities of the ECOS are continuously improved in an innovative way.

We will be happy to advise you on site with our Sommerauer base partners to help you select the optimum biomass heating system, the best possible subsidy and individualised room layout. We have been specialising in individual special solutions for 30 years.

Advantages of the new ECOS technology:

  • State-of-the-art hybrid biomass boiler (pellet/wood chips) with maximum ease of use (ECO SMARTTRONIC intelligent control, ALEXA voice control (VOICE CONTROL+), patented WIZARD+ software commissioning assistant, smartphone 3D user interface with 3D icons displaying real-time data and 3D objects (BIONIC+), video instructions and digital operating manual, Sommerauer app with 1:1 full access, SmartHome Loxone (ECO SMARTHOME+). 

  • Extensive patent portfolio: Patented USPs as global competitive advantages, covering both ease of use and technical fields. 10 granted patents (European and other countries) with 84 invention variations, 5 patent applications scheduled for patent grant, and a large number of other European patent applications.  

  • 24 efficiency world records (conventional up to 98% efficiency, condensing up to 110.4% efficiency). Proven with market analysisreport and boiler test report from TÜV SÜD Austria. 

  • 23 dust world records (up to 0.2 mg/MJ). Proven with market analysis reports and boiler test reports from TÜV SÜD Austria. This makes the ECOS verifiably the most energy-efficient and at the same time the cleanest hybrid biomass boiler in the world. Highest energy efficiency and maximum subsidies can thus be implemented. 

  • Fully automatic fuel detection and control (ECO AUTOMATIC FUEL+). 

  • Artificial intelligence (AI) LOOP+ for essential boiler functionalities. 

  • High cost efficiency of the biomass boiler (variable sales price due to modular design, common parts in use). 

  • Official GUINNESS WORLD RECORDS world record as the most energy-efficient hybrid biomass heating system in the world (98% efficiency, pellets). 

  • Weather forecast energy saving function (ECO+). 

  • Maximum CO2 savings realisable in the biomass heating market.
