Heat pumps are in high demand in the Netherlands and are one of the key solutions in the transition to energy-efficient heating. New buildings must meet strict BENG energy-performance requirements. As a result, there is strong demand for professionals who can install, commission and maintain heat pumps to a professional standard.
At our training centre, you will gain the theoretical knowledge and practical skills needed to work professionally with heat pumps in the Netherlands.
INT Services is an official examination centre registered with InstallQ. After successfully completing the course and passing the official examination, you will receive an INT Services certificate and your qualification will be registered in the official Dutch technical register.
