Abstract
An apparatus for dispensing a predetermined volume of a warm liquid includes a heater, a pump and a temperature sensor sensitive to the temperature of the liquid upstream of the heater. A controller is arranged to receive upstream temperature data from the temperature sensor, calculate the amount of energy required to reach a desired final temperature, energize the heater for a calculated period of ON time, and dispense liquid for a calculated period of time that is at least partly contemporaneous with the calculated period of ON time. After the heater has been de-energized, the dispensed liquid removes residual heat so that the average temperature after dispensing the predetermined volume is the desired final temperature.
