A coffeemaker includes a housing and a water reservoir contained within the housing. A carafe is supported on a base portion of the housing. A spreader is mounted within the housing. A hot water generator has an inlet connected to the water reservoir and an outlet connected to the spreader. The hot water generator has a generally shallow V-shape. An enclosure is supported within the housing and surrounds the hot water generator. The contact area between the surfaces of the generator and the enclosure is relatively minimal. The major portion of the surfaces of the enclosure and the hot water generator are spaced from each other to form an insulating air barrier to retain the heat generated by the hot water generator within the enclosure.
