Abstract:
1. A water heater system comprising: a water tank; a heat source disposed proximate the water tank; a main controller disposed proximate the water tank, the main controller configured to control the heat source, the main controller including a maximum temperature set point and an operating temperature set point, the main controller operating in accordance with a particular temperature differential; and a remote controller in communication with the main controller and configured to accept a request from a user for additional hot water capacity, resulting in the remote controller communicating a boost request to the main controller, wherein the boost request results in the main controller temporarily operating in accordance with a boost temperature set point that is higher than the operating temperature set point; wherein the main controller, upon receiving the boost request from the user, activates a timer and operates the heat source in accordance with the boost temperature set point for a predetermined length of time measured by the timer; and wherein the main controller sets the boost temperature set point at a temperature that is a predetermined amount above the operating temperature set point as long as the resulting boost temperature set point does not exceed the maximum temperature set point of the main controller.
