Bunn-O-Matic came out with a different drip-brew machine. In this type of coffeemaker, the machine uses a holding tank or boiler pre-filled with water. When the machine is turned on, all of the water in the holding tank is brought to near boiling point (approximately 200–207 °F or 93–97 °C) using a thermostatically-controlled heating element. When water is poured into a top-mounted tray, it descends into a funnel and tube which delivers the cold water to the bottom of the boiler. The less-dense hot water in the boiler is displaced out of the tank and into a tube leading to the spray head, where it drips into a brew basket containing the ground coffee. The pourover, water displacement method of coffeemaking tends to produce brewed coffee at a much faster rate than standard drip designs. Its primary disadvantage is increased electricity consumption in order to preheat the water in the boiler. Additionally, the water displacement method is most efficient when used to brew coffee at the machine's maximum or near-maximum capacity, as typically found in restaurant or office usage. In 1963, Bunn introduced the first automatic coffee brewer, which connected to a waterline for an automatic water feed.

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.
So while yes, $150 (current price as I review this item) is a good chunk of change, I honestly believe it’s worth it. This is a high-quality machine that will hopefully last a very, very long time. The quality of the espresso is very good, and in the long run, it will save you the cost of espresso-based drinks at the coffee shop. It all evens out in the end! If you are considering buying this, my advice is to just do it. It’s worth it! Love love love!”
It can take a little while to get to know the ins and outs of a new coffee maker. In CR’s labs, each drip coffee maker we test brews roughly 65 cups by the time our engineers are through with it. And brewing is just one of many aspects we look at. We test for handling and convenience, too, so you can choose a model that helps you sail through morning madness.
