Welcome to the project homepage of the joint venture of H.S.W. GmbH Rostock and the engineering office Freund!

H.S.W. GmbH and the engineering office igf, Rostock, have carried out their own thermal / geothermal response tests for nine years now (e.g. thermal response tests in Rostock, Ruegen, Warzaw, Berlin, Hamburg, Wismar, Frankfurt, Munich and Kolberg).

We have a modern mobile TRT/GRT test unit with special programmable logic controller (PLC) available. It ensures a high quality of the measurements.

This TRT/GRT test unit is used for services in Germany and all over Central Europe. Our mobile test unit can be even used internationally via Air-Express.

In case you are interested in executing a thermal / geothermal response test – get in contact with us. We will provide you an offer for a (geo-) thermal response test short-term, including a list of all related costs. Make use of our query-fax which is available at the download section of this website (queries via email are possible as well).
