Abstract
A coffee pot heating unit is provided with a base, a heating area associated with the base and having a size sufficient to accommodate a bottom portion of a coffee container, and a heating apparatus associated with the heating area to heat the heating area. The heating apparatus may include a heating element, and the heating apparatus may have an electrical resistance such that the heating apparatus generates no greater than about 80 watts of electrical power when the heating apparatus is connected to a 120-volt electrical power source. The heating apparatus generates a substantially fixed and constant electrical power output that does not change substantially while the heating apparatus is connected to the 120-volt power source.
