Water heating systems and methods
A water heating system, comprises a tank, a bracket, a heating element, and a controller. The bracket has a hole and a notch. The heating element is mounted on the tank, and the heating element passes through the hole. The controller is inserted into the notch. Further, the controller comprises a relay coupled to the heating element and logic configured to control a state of the relay. The logic resides in a portion of the controller that is inserted into the notch.
1. A water heating system, comprising:
a tank;
a bracket having a hole and a notch;
a heating element mounted on the tank, the heating element passing through the hole; and
a controller having a relay coupled to the heating element and logic configured to control a state of the relay,
wherein the logic resides in a portion of the controller positioned inside the notch,
wherein the relay resides in a portion of the controller positioned outside of the notch,
wherein the controller has a temperature sensor, and wherein the temperature sensor resides in the portion positioned inside the notch,
wherein the controller has an emergency shut-off apparatus residing in the portion positioned outside of the notch, and
wherein the controller has a printed circuit board (PCB), and wherein a movable portion of the emergency shut-off apparatus extends through the PCB.
2. The system of claim 1 , wherein the controller has a transformer residing in the portion that is outside of the notch.
3. The system of claim 2 , wherein the bracket has a first arm and a second arm defining the notch, wherein a width of the notch from the first arm to the second arm is less than a width of the portion outside of the notch.
4. The system of claim 3 , wherein the relay and the transformer are positioned on an opposite side of the PCB relative to the temperature sensor.
5. The system of claim 1 , wherein the bracket has a first arm and a second arm defining the notch, wherein a width of the notch from the first arm to the second arm is less than a width of the portion outside of the notch.
6. A water heating system, comprising:
a tank;
a heating element mounted on the tank;
a housing mounted on the tank and having a first portion and a second portion;
a controller positioned in the housing, the controller having a relay coupled to the heating element and logic configured to control a state of the relay,
wherein the control logic resides in the first portion,
wherein the relay resides in the second portion,
wherein the controller has a temperature sensor coupled to the logic, and wherein the temperature sensor resides in the first portion,
wherein the controller has an emergency shut-off apparatus residing in the second portion, and
wherein the controller has a printed circuit board (PCB), and wherein a movable portion of the emergency shut-off apparatus extends through the PCB.
7. The system of claim 6 , wherein the controller has a transformer residing in the second portion.
8. The system of claim 7 , wherein the relay and the transformer are positioned on an opposite side of the PCB relative to the temperature sensor.
