Operatioin of Feedwater Heaters.

[nw-mailing-list at nwhs.org]

What is involved in the operation of a feedwater heater?  Does the fireman have to operate the cold water pump and hotwater pump separately?  Or, do the two pumps turn on with the same control?  How does this system differ from the operation of the injector system?
