NC-2009 EAp2: Minimum Energy Performance
In the proposed design, we are using a water-to-water heat pump for the sole purpose of service water heating. Voltage and Amps are 460v and 140 RLA, respectively. It is coupled with an unfired storage tank (Which Table 7.8 requires to have R-12.5 insulation). What water heater from Table 7.8 should I use in the Baseline model?

See Table G3.1-#11(Baseline) for the details on sizing, etc. Basically you will be modeling an electric storage type water heater in the Baseline sized according to Section 7.4.1.
