It is used to establish theappropriate water flow rate.HCIRC-HEAD*HCIRC-IMPELLER-EFF*HCIRC-LOSSHCIRC-MOTDR-EFF*specifies the head pressure in the hot water circulationloop. If this is set equal to 0., circulation pump powerwi 11 also be set to zero.specifies the efficiency of the pump impeller in the hotwater circulation loop.is the fraction of the design load that is lost to theenvironment from the circulation loop and therefore doesno useful heating. In the case of a hot water boiler,this value does not include any heat gain caused by pumpenergy. If the user has input a FURNACE, this keyword isignored.specifies the efficiency of the pump motor in the hotwater circulation loop.* Note that if the user has input a STM-BOILER, ELEC-STM-BOILER, or FURNACE,this keyword is ignored. Note also that the heating load satisfied by aDHW-HEATER or ELEC-DHW-HEATER is not considered to be a part of this heatingcirculation loop.V.33 (Revised 5/81)
