A heating element continues to maintain the coffee at the selected temperature. A thermostat determines when the coffee has brewed sufficiently, then turns the percolating system off. The resulting hot coffee then drips through holes in the basket base and into the main compartment to be recycled. At the top, water falls into the coffee basket and soaks up all that great coffee flavor from the grounds. Percolator coffee makers heat a small amount of water in the base of the unit, forming steam that pushes the hot water up a tube in the center of the percolator. An element under the carafe keeps the coffee warm. The resulting hot coffee falls into a carafe. ![]() Most drip coffee makers are activated by switches and timers in the control panel, heating water and pumping it up to drop through the coffee basket. Simply plug it in, connect your device needing power, press the desired time, and RELAX.There are two types of coffee makers in common use: those that drip hot water once through the coffee grounds, and those that percolate, or recycle, the water through the grounds many times.
