So my installer has 200 plus installations (supposedly just like mine) minus the Rheem Marathon electric hot water heater as they are using conventional (not Rheem Marathon) electric hot waters instead. In short, the amount of water required for desuperheating superheated steam depends on the temperature of the steam and the degrees of temperature to be lowered. It is essential in such cases, to keep the superheated steam pressure constant. Videre er de bygget av tunge materialer og har ingen bevegelige deler som kan forstyrre deres funksjon.
