Neutrals

Why is it on certain appliances such as a hot water tank, there is no neutral, yet on others such as a dryer there is a neutral?

The water htr does not have any 120 volt requirements. The dryer has a 120 motor to turn the drum.

The need for a neutral is usually dependent on the power requiremnets. Certain appliances require only the 220 volt power with no need to supply any 120 volt power to anything in the unit. In this case only 2 hot wires are needed. This can be found in hot water tanks or on many baseboard heaters. But many large appliances such as dryers and stoves use both 220 volt power for some parts such as the dryer elements or the oven elements and 120 volt power for other parts such as the motor or the electronic controls on a dryer or the convenience receptacle on the stove.
