The Coffee Flow Through Heater (figure 4-19) has a large heater
element; and a small heater element. The Steam Flow Heater has
only one heater element (refer to figure 4-20)
Each Flow Through Heater has a Positive Thermal Coefficient

unit for temperature control. In addition, a Thermostat is connected
in series with the heater element. Should the temperature become
too high, the Thermostat interrupts the power to the heater
element
