The invention relates to a warming arrangement having a warming system for warming a steam turbine. The warming system has a makeup line and recycle line fluidly connected to the steam turbine. A gas moving device and a heater are located in either of these two lines. The warming system further includes a pressure measurement device that is configured and arranged to determine a gauge pressure in the steam turbine as well as a controller. The controller is configured to control a flow rate of the warming gas through the steam turbine, based on the pressure measurement device.
