Abstract

An electronic instantaneous electric hot water system and method of operation is described and comprises a flow sensor, a heating element and an input temperature sensor for measuring the input temperature of the water. Additionally, a second temperature sensor that measures the output temperature may be included. A user interface receives a set point temperature within a predefined temperature range for an output water temperature and an electronic temperature controller controls the amount of power supplied to the heating element. The electronic temperature controller determines the amount of power to be supplied to using the temperature measured by the input temperature sensor and the flow sensor. The controller is configured to prevent overshoot of the output temperature to prevent scalding. Further, the maximum temperature is predetermined or pre-set and can only be changed using an authorisation code. Control of overshoot and use of an authorisation code for setting the maximum temperature facilitate use in schools, child care centres, hospitals, or other environments.
