We are a subsidiary of ENERTECH AB and, as a trading and service company for heat generation, we are responsible for the entire Swiss market. We purchase most of our products from our sister companies within the group.

Since the beginning of 2004, the sister companies CTC Wärme AG, founded in 1962, and GIERSCH Systherm AG, founded in 1995, have merged to form the current company CTC GIERSCH AG. Thanks to this merger, we are now able to offer our customers the entire spectrum of heat generation. Since September 14, 2020, we have been on the market as CTC AG. Everything remains the same, only the name is new.
