The bathroom water temperature is very hot, we don't need the water to be that high, we don't shower at work. The water temperature just needs to be luke warm for use. By lowering the water heater temperature we can save funding. The on-demand systems also provide great efficiency as they provide warm water whenever the water is used, as opposed to the old systems that continually heat up water (even on weekends when demand is nill or low).
