An adjustable temperature warming plate for an electric coffee maker in which a fixedly positioned metal hot plate has an electric heating element disposed beneath and adjacent the hot plate with the supporting means for the electric heating element permitting the heating element to pivot about a contact point near the edge of the hot plate for varying the thermal coupling of the heating element to the hot plate by changing the spacing between the heating element and the hot plate. A pressure element is provided to urge the heater toward the contact point and a setting element is provided to adjust the spacing between the heating element and the hot plate. This provides a simple and reliable means for varying the thermal coupling of the heating element to the hot plate and consequently the temperature of the warming plate. The heating element includes a tube unitary therewith forming a continuous flow water heating tube for the coffee maker.
