How does a continuous pilot differ from other pilot types?

A continuous pilot differs from other pilot types primarily in its operational characteristic of remaining lit at all times, regardless of whether the main burner is active. This constant flame ensures that ignition for the main burner is immediate and reliable whenever it is needed. In contrast to other types of pilots, such as intermittent pilots, which may only ignite when the main burner activates, the continuous pilot is designed to provide a consistent source of ignition, thereby enhancing the safety and efficiency of appliance operation.

This operational durability is especially important in some heating systems, as it can reduce the chances of incomplete combustion and fuel wastage. Since the pilot stays lit, it can promptly ignite the main burner without delay, which is critical in systems where timing and efficiency are crucial for safe operations. The other options either describe functionalities that are typical of different pilot types or apply to features not associated with continuous pilots.
