offspring

With the goal of acquiring well-trained employees, the idea of promoting and training new talent took shape. Starting in September, the company began its first in-house training program for the profession of installer and heating technician or plant mechanic for sanitary, heating, and air conditioning technology. This demanding training lasts almost four years. To date, all eight trainees have successfully completed their apprenticeships – a fact of which we are proud!

GMBH

The sole proprietorship transitions into a limited liability company (GmbH). The company grows and expands its business areas. Renewable energies such as solar and geothermal energy enable the construction of even more efficient heating and hot water systems. Additionally, the utilization of rain and gray water becomes another highly successful business model.
