References from the field of geothermal energy
Since the end of the 1990s, the H.S.W. GmbH dealt with applications of near-surface geothermal energy as a part of applied geology. Even back in the days of relatively low energy costs, the potential of geothermal energy was recognized and a separate department "geothermal energy" has been created in 2003. The extensive experience of numerous successful industry and research projects speak for the exceptional skills of H.S.W. GmbH in the design of geothermal systems. National and international references of this department include the implementation of nearly 500 geothermal response tests as well as the design (including calculations, plans, professional accompaniments) of more than 1,000 different geothermal projects.
