A portable liquid dispensing apparatus is described, which comprises a battery, a heating element, a liquid reservoir, a pump, an outlet, and a pipe, extending from the reservoir to the outlet and passing adjacent the heating element. In operation, the pump drives liquid from the reservoir into and through the pipe while the power source causes the heating element to heat the liquid passing through the portion of the pipe adjacent to the heating element to be expelled from the outlet at a temperature greater than the ambient temperature.
