Certification of Eco-efficient Substations

Certification, in accordance with our guidelines, enables an increased product quality level, sound competition and more reliable and easier procurement. Furthermore, the guidelines increase cost efficiency by avoiding multiple testing, and inspections in the production of eco-efficient substations for district heating.


The EHP004 Certification Programme certifies Eco-Efficient Substations for District Heating (CWA 16975:2016) through our EHP004 Guidelines.


All producers are encouraged to apply the certification procedure according to these guidelines, and district heating companies are encouraged to only buy and use certified products.
