Heatpump KEYMARK steering committee (HPSC)

The heat pump KEYMARK steering committee consists of representatives of manufacturers, certification bodies, testing institutes, the EHPA and the secretariat. It meets at least two times per year to decide on open issues and next steps in the scheme development. The steering committee can make suggestions for vote to the HPSG and can also ask the different committees for a special opinion.

Any topics or issues raised by the scheme members and communicated to the secretariat will be considered by the steering committee for discussion. The HPSG members are warmly invited to send proposals and participate as guests in the steering committee meetings if they are willing to discuss any specific topics.
