Question:

Does a standard coffee maker really boild the water?

Do coffee makers boil the water to a significant degree that the final water can be considered quot;more purequot;? Some people use this claim to suggest using tap water or bottled water in the coffee maker is the same.

Answer:

Generally when water is boiled it kills germs and thus is useful for drinkingFor the germs to be killed, the water has to be boiled to a certain point and remain in that state for almost 1 minute The water in a coffee machine is not boiled to this point, since it is used for coffee and the contents of the coffee mug has a heater under the surface to keep it hotWhen you pour in cold water, it flows from the bucket through the hole in the bottom of the bucket and into the orange tube The water then flows through the one-way valve into the aluminum tube in the heating element, and then partially up through the black tubeThis all happens naturally because of gravity When you turn on the switch, the heating element starts heating the aluminum tube, and eventually the water in the tube boils When the water boils, the bubbles rise up in the black tubeWhat happens next is exactly what happens in a typical aquarium filter: The tube is small enough and the bubbles are big enough that a column of water can ride upward on top of the bubble The water flows out the end of the black tube to drip into the coffeeThis boiling-water pump, by the way, is the same mechanism that drives a percolator-type coffee machine As you can see, there is no mechanical pump of any type and really no moving parts (except for the moving portion of the one-way valve)This makes coffee machines extremely reliablehope this helps
