A water heating system, comprise a tank, a heating element, and a controller that is coupled to the heating element. The controller comprises a base, a housing, a relay, logic and, a temperature sensor. The base is composed of thermally conductive material, and the housing is composed of electrically insulating material. The housing is coupled to the base, and the logic is configured to control the a state of the relay. Further, the temperature sensor contacts the base and is coupled to the logic.

1. A water heater controller, comprising: a base composed of thermally conductive material;a housing composed of electrically insulating material, the housing coupled to the base;a power-source input;a relay configured to selectively convey power from the power-source input to a heating element;logic for controlling an operational state of the relay;a temperature sensor contacting the base and coupled to the logic; andan emergency shut off apparatus disposed within the housing and configured to disable the heating element independent of the logic and without disabling the logic by causing an open circuit condition between the power-source input and the heating element. 2. The controller of claim 1, wherein the temperature sensor is mounted on a component composed of thermally insulating material. 3. The controller of claim 1, further comprising a printed circuit board having a first side and a second side, the first side opposite of the second side, wherein the relay is mounted on the first side of the PCB, and wherein the temperature sensor is positioned between the PCB and the base on the second side of the PCB. 4. The controller of claim 3, wherein the temperature sensor is mounted on a component composed of thermally insulating material. 5. The controller of claim 3, wherein the controller is mounted on a tank via a bracket, the bracket having a notch, and wherein the temperature sensor is positioned in a portion of the controller inserted into the notch. 6. The controller of claim 3, wherein the emergency shut-off apparatus is mounted on the first side of the PCB. 7. The controller of claim 6, wherein the logic is mounted on the first side of the PCB. 8. The controller of claim 1, wherein the controller is mounted on a tank via a bracket, the bracket having a notch, and wherein the temperature sensor is positioned in a portion of the controller inserted into the notch. 9. The controller of claim 8, wherein the relay and the emergency shut-off apparatus are positioned in a portion of the controller outside of the notch. 10. A water heating system, comprising: a tank;a heating element; anda controller coupled to the heating element, the controller comprising: a base composed of thermally conductive material;a housing composed of electrically insulating material, the housing coupled to the base;a relay coupled to the heating element;logic configured to control a state of the relay;a temperature sensor contacting the base and coupled to the logic; andan emergency shut-off apparatus disposed within the housing and configured to disable at least the heating elements independent of, and without disabling, the logic controlling the state of the relay. 11. The system of claim 10, wherein the temperature sensor is mounted on a component composed of thermally insulating material. 12. The system of claim 10, further comprising a printed circuit board having a first side and a second side, the first side opposite of the second side, wherein the relay is mounted on the first side of the PCB, and wherein the temperature sensor is positioned between the PCB and the base on the second side of the PCB. 13. The system of claim 12, wherein the temperature sensor is mounted on a component composed of thermally insulating material. 14. The system of claim 12, wherein the controller is mounted on a tank via a bracket, the bracket having a notch, and wherein the temperature sensor is positioned in a portion of the controller inserted into the notch. 15. The system of claim 12, wherein the logic is mounted on the first side of the PCB. 16. The system of claim 10, wherein the controller is mounted on a tank via a bracket, the bracket having a first arm and a second arm, and wherein the temperature sensor is positioned in a portion of the controller between the first and second arms. 17. The system of claim 16, wherein the relay is positioned in a portion of the controller that is outside of a notch formed by the first and second arms.
