Geothermal area of activity: Specialization in near-surface geothermal energy with borehole heat exchangers down to a depth of 200 m. If necessary, complete geothermal development right into the building, including a pre-assembled and pressure-tested brine distributor. Recognized position of the drilling and use notification at the responsible authority as a certified DVGW specialist company. Objective and individual advice for each individual case based on our many years of practice (since 1990) and experience to achieve an optimal price-performance ratio. For larger systems, all preparatory measures to create a thermal response test with EED simulation are carried out to optimize the design of a geothermal probe field.
