Title:
SYSTEM AND METHOD FOR ACCELLERATED HEATING OF A FLUID
Document Type and Number:
WIPO Patent Application WO/2019/139958
Kind Code:
A1
Abstract:
A water heating system including a tank, a first heating element, a second heating element, a first temperature sensor, a second temperature sensor, a controller having an electronic processor and a memory. The controller is configured to determine an output temperature setpoint, determine whether a period of expected high water demand is approaching, and in response to determining that the period of expected high water demand is approaching, activate the second heating element. The controller is further configured to deactivate the second heating element when a second temperature sensed by the second temperature sensor crosses a second temperature threshold, activate the first heating element when the second temperature crosses the second temperature threshold, and deactivate the first heating element. Wherein the first temperature threshold is lower than the second temperature threshold and the first and second temperature thresholds are higher than the output temperature setpoint.
