French press makers require hot water from a separate source while a vacpot which is called a siphon brewer or vacuum brewed coffee uses hot or cold water depending how one wants to use it. Another that requires hot water may not be considered a coffee maker but the coffee dripper that has a filter in it and sits on your cup or mug does make coffee. The most common maker is a drip coffee maker. This is true whether it is a pour over where hot water is poured over the grounds or hot water is pumped up from a side source and allowed spray water over the grounds. These makers have two shapes of filters known as the cone and the basket shape that has more drip area. Some drip makers offer a low electric heated hot plate while others offer radiant heat. Drip makers come in closed sealed and open coffee dispensing. Closed and sealed dispensing systems often close off the flavor and aroma while the coffee is being made.
Those that pre-heat the water include Bunn coffee makers. These are great when you need another pot of coffee in a hurry. Some offer a fresh 12 cups of coffee in as little as 2.5 or 3 minutes. Another advantage of this type of maker which is claimed by many is that the preheated water makes a much better tasting cup of coffee. Espresso coffee machines make coffee under a pressure system that is usually at 15 bar of pressure. Note here there are other coffee machines that make coffee under pressure but true espresso machines are at 15 bar. The coffee grounds are much finer than regular thus a thicker liquid is produced by the steam that is driven through the coffee. Espresso machines also appear different and work differently as well. A manual pump machine is just that a manual machine where you do every step. A semi automatic does some of the process and can be set on how to do them. The super automatic is fully automatic. It will make different kinds of espresso that you can select it will then grind the coffee to your specifications and brew your selection the number of times you want it made. Some super automatic machines allow you to make different selections of an espresso at the touch of a button.
