A heater control system is disclosed. In an embodiment, the heater control system includes a fluid heater that includes a heating element. The heating element controlled by a switch. The heater control system also includes a controller that can operate the switch. The controller is configured to determine whether a temperature associated with the fluid heater is below a predetermined temperature threshold. The controller causes the switch to transition to an operational state when the temperature is below the predetermined temperature threshold allowing current to flow through the at least one heating element.
