WebExpert Answer. Consider a regenerative vapor power cycle with two feedwater heaters, a closed one and an open one, and reheat. Steam enters the first turbine stage at 12MPa,480∘C, and expands to 2 MPa. Some steam is extracted at 2 MPa and fed to the closed feedwater heater. The remainder is reheated at 2MPa to 440∘C and then … WebMake sure that there is sufficient power going into the water heater; you should have two wires going into the unit that have 120 volts each. If you are not getting a full 240 volts, then there is a problem with the breaker, and it may need to be replaced. (I will not be going over this in this article, it’s a whole other can of worms). comcast extending promotional rate chat
