Regulation 7 Steam

The reckonable energy in respect of steam supplied to any place within the relevant premises shall be calculated by taking the enthalpy of the steam and by dividing it by the efficiency of the system which generates the steam and supplies it to the place where it is used.

Appropriate adjustments shall be made to take account of subsequent uses of the steam elsewhere and any reduction in the pressure of steam when it leaves that place compared with its pressure when it is supplied to that place.
