Tankless, point-of-use water heaters are commercially available and are claimed to reduce energy usage since water is only heated when needed. Consider an application in a bathroom where hot water is needed to be produced at a rate of 0.2 L/s by raising the temperature from 10 °C to 45 °C. (a) Draw a schematic of the system. Using electric resistance heaters, determine (b) the required power (kW) needed to raise the water temperature and (c) the entropy generation rate (kW/K).
