Cooling Load Calculation
wattage = the rated power of the fan motors (Watts) 1000 = convert from watts to kw. In this cold room evaporator we''ll be using 3 fans rated at 200W each and estimate that they will be running for 14 hours per day. Calculation: Q = fans x time x wattage / 1000. Q = 3 x 14 hours x 200W / 1000. Q = 8.4kWh/day.

Storage Water Heaters | Department of Energy
A single-family storage water heater offers a ready reservoir -- from 20 to 80 gallons -- of hot water. It operates by releasing hot water from the top of the tank when you turn on the hot water tap. To replace that hot water, cold water enters the bottom of the tank through the dip tube where it is heated, ensuring that the tank is always full.
