No, a block heater does not heat all the time it's plugged in. It only activates when the engine temperature drops below a certain level or when a thermostat inside the heater signals that heating is needed. Typically, it is recommended to plug in the block heater a few hours before starting the vehicle in cold weather for optimal results. This helps ensure the engine is warm enough for easy starting and reduces wear on the engine.
