Abstract
A liquid heater includes an electrical power supplier and a heating passage configured to receive unheated liquid. The heating passage is defined by a first electrode and a second electrode. The first and second electrodes are electrically connected to the electrical power supplier. The unheated liquid received into the heating passage generates heat when an electric current flows through the liquid and between the first and second electrodes. The liquid heater is utilized in beverage product dispensers and heated liquid food product dispensers.
