About Lindner & Sommerauer

Establishment 1991

Lindner & Sommerauer was founded in 1991 by Hermann Lindner and Christian Sommerauer to manufacture biomass boilers. They are based in Upper Austria, the European centre of excellence for wood heating systems, and are one of Europe’s leading biomass boiler manufacturers.

They run the company under a firm ethos of creating environmentally friendly technology that works in harmony with nature. The result is high-efficiency biomass boilers built by dedicated and committed experts. 

Technical Excellence

Over twenty years’ experience has enabled Lindner & Sommerauer to develop some of the most advanced wood chip and wood pellet biomass boiler heating systems on the market.

All Lindner and Sommerauer biomass boilers are fitted with an electronic touch screen control panel. This gives the boiler’s user access to vital performance information and puts them in control of all key functions such as timers, thermostats, heat outputs and boiler efficiencies.

2013

 Rainbow Heat and Power are awarded the exclusive UK distribution for Lindner & Sommerauer biomass boilers. After extensive testing of the boilers and thorough installer training, Rainbow Heart and Power began installing the Lindner & Sommerauer range in the UK during the 2013 heating season.
