    Power is delivered to each element through a thermostat—a switch that senses the water temperature when the temperature drops, the switch closes to allow current flow, and it opens when the temperature reaches its preset limit thermostats have a dial for setting the maximum water temperature—generally between 130 degrees and 140 degreesf, or as low as about 120 degreesf for increased energy.
