Title: HEAT EXCHANGER VALVE ARRANGEMENT, HEATING SYSTEM AND METHOD FOR OPERATION A HEATING SYSTEM
Abstract:
A heat exchanger valve arrangement has a pressure control valve (17), said pressure control valve (17) comprising a valve element (18) cooperating with a throttling element (19) and controlling a differential pressure (P2-P3). The invention provides means with which pumping energy in a heating system can be kept low. To this end detecting means (28, 29) are provided detecting whether said differential pressure (P2-P3) exceeds a predetermined minimum value.
