Factory service

The ZEWOTHERM factory customer service enables a quick commissioning of the heat pump and/or ventilation system as well as a simultaneous inspection of the entire installation. The service is present throughout Germany and offers fast and professional support. In addition to commissioning, it is also available in the event of any faults in the system.

Please note that the order is always placed in writing by the wholesaler involved. Our technician will draw up a corresponding protocol. Unfortunately, this service cannot be offered for mixed installations containing products from other manufacturers. For full warranty maintenance, the heat pump system must be commissioned by the factory customer service or a certified refrigeration specialist. Please register the factory commissioning at least 10 working days before the desired date! Please use the corresponding registration forms, which you can find in the download area.
