25、, energy rate and energy efficiency of thebooster for continuous water flow at 50% of flow capacity isdetermined with the booster heater inlet water supplied at 110+03 F (43.3+01.7 C) and 140+03 F (60.0+01.7 C).4.5 The preheat energy consumption and time and idle/standby energy consumption rate are
26、determined while thebooster heater is operating with the thermostat(s) set at thecalibrated setting(s) to deliver 183 6 3 F at the booster heateroutlet.
