Cut-out Pressure Delta. S = 105 80. P2. Cut-in Pressure Delta. S = 25. Factor of Evaporation. Water enters the boiler at 225°F. The boiler pressure is 100 psi and the boiler water temperature is 338°F. The latent heat is 881 Btu.
When pressure is lost in the steam heating system steam leaves the heating units resulting in a more rapid loss of heat than in a hot water heating system. In addition the steam heating system has a longer recovery time in producing heat after the boiler is shut down. Boilers are used in both hot water heating systems and steam heating systems.
