It is worth mentioning that the HWCB exergetic efficiency is fixed to 8.4% (bold circle in Figure 1) at high fire and a return water temperature of 100[degrees]F, but the exergetic efficiency of the VVHCB varies in range from 11.1% to 20.26% depending on the temperature of the supply vapor.
The same BoilerCapacity and energetic efficiency are assumed for HWCB and VVHCB.
