Come funziona:

The water in the Hot Water Loop is heated by means of steam. The amount of steam is regulated by a steam control valve, based on the set point of a temperature controller mounted in the hot water outlet line. A hot water pump ensures a constant flow to the Hot Water Loop heat exchanger, and makes recirculation possible when the engine is at low load or stopped. This pump must be running when the Hot Water Loop is used for engine preheating. A blinded flange connection makes it possible to connect the Hot Water Loop for various heating or preheating purposes.
