Here is the part that matters most in Middle Tennessee: our long, humid summers. That moisture works its way into everything, including the cool interior of an unused fireplace, where it encourages condensation and the surface rust that loves to start on metal burner components. The small, constant warmth from a standing pilot keeps the firebox and its parts slightly warmer and drier than the surrounding air, which helps hold that off. In a dry desert climate this benefit barely registers. Here, where humidity lingers for months, it carries real weight, especially if your fireplace sits in a basement, against an exterior wall, or has had any past moisture issues. The gentle warmth also makes the firebox less inviting to spiders and insects. More on the trade-offs here.
