An electric drip coffee maker can also be referred to as a dripolator. It normally works by admitting water from a cold water reservoir into a flexible hose in the base of the reservoir leading directly to a thin metal tube or heating chamber (usually, of aluminum), where a heating element surrounding the metal tube heats the water. The heated water moves through the machine using the thermosiphon principle. Thermally-induced pressure and the siphoning effect move the heated water through an insulated rubber or vinyl riser hose, into a spray head, and onto the ground coffee, which is contained in a brew basket mounted below the spray head. The coffee passes through a filter and drips down into the carafe. A one-way valve in the tubing prevents water from siphoning back into the reservoir. A thermostat attached to the heating element turns off the heating element as needed to prevent overheating the water in the metal tube (overheating would produce only steam in the supply hose), then turns back on when the water cools below a certain threshold. For a standard 10-12 cup drip coffeemaker, using a more powerful thermostatically-controlled heating element (in terms of wattage produced), can heat increased amounts of water more quickly using larger heating chambers, generally producing higher average water temperatures at the spray head over the entire brewing cycle. This process can be further improved by changing the aluminum construction of most heating chambers to a metal with superior heat transfer qualities, such as copper.

Domestic electrification simplified the operation of percolators by providing for a self-contained, electrically powered heating element that removed the need to use a stovetop burner. A critical element in the success of the electric coffee maker was the creation of safe and secure fuses and heating elements. In an article in House Furnishing Review, May 1915, Lewis Stephenson of Landers, Frary and Clark described a modular safety plug being used in his company's Universal appliances, and the advent of numerous patents and innovations in temperature control and circuit breakers provided for the success of many new percolator and vacuum models. While early percolators had utilized all-glass construction (prized for maintaining purity of flavor), most percolators made from the 1930s were constructed of metal, especially aluminum and nickel-plated copper.

If all you’re looking for is a gorgeous cup of coffee and no fuss, we strongly recommend the Bonavita BV1900TS. It’s the smallest machine among our top picks and, at $190, the cheapest. Even better, it ranked in the top three out of 10 during our taste tests. It’s also the simplest and most straightforward: one button you click to start brewing, and that’s it. You can’t program brew times; you can’t play around with water temperature; and it even lacks some convenient touches like a brew basket that attaches to the machine (when you’re done brewing, you have to place the brew basket on a plate or in the sink before it makes a total mess). But it’s by far the fastest machine out of our top picks, brewing up a full eight-cup pot in under six minutes. It’s a straightforward, high-end coffee maker that leaves little to complain about.
CR’s take: If you’re an aficionado of fresh ground coffee, this Black+Decker is the brewer to buy. As the name suggests, the Mill & Brew goes that extra mile, grinding whole coffee beans just before brewing. As a result, the machine is capable of making a great pot of coffee. Made of plastic with stainless steel accents, this model is easy to use and to clean, earning a Very Good rating in our convenience tests. It allows you to adjust brew strength, and it’s programmable, so you can set it to grind and brew just before you wake up.
