Also in large scale machines there are options of keeping the water heated for a longer time and the coffee is constantly brewed so that the supply is almost instantaneous when switched on.

The speed is also not much to talk about and hence the supply is done a long time after the switch is turned on as the brewing and heating starts again and again for every new cup of coffee.

This increases the pressure in the lower chamber and forces the water upward into the upper chamber that you add just before the water begins to rise. Brew for about 1.5 minutes then remove from heat the gases in the lower chamber cool and draws the brewed coffee downward via suction caused by a partial vacuum that ensures accurate extraction of oils and caffeine for a cleaner unit without the bitter taste.
