The CSTG test method

The CSTG test method is based on a simple ‘input/output’ correlation and can only be applied for solar domestic hot water systems without auxiliary heating devices in the store. This method is standardized in ISO 9459-2. Since solar heating systems of this type are rare in northern and central Europe, the CSTG test procedure is predominantly applied in test laboratories in South Europe.
