What is a firebox?

A firebox is the compartment where the fuel is burned in a fireplace, wood stove, or other heating appliance. It is usually made of heat-resistant materials such as firebrick or steel. The firebox is designed to contain the fire safely and efficiently, providing a source of heat for the room without allowing the fire to spread beyond its boundaries. Fireboxes can vary in size and shape depending on the type of heating appliance and the amount of heat output required. Proper maintenance of the firebox is important to ensure safe and effective operation of the heating appliance.
