A gravity feed iron is a type of iron that uses the force of gravity to supply water to the steam chamber. It is different from a traditional iron which uses a water reservoir that must be filled manually.

The gravity feed iron has a water bottle that can be filled with water and placed upside down on the iron. As the iron heats up, the water in the bottle is drawn into the steam chamber through a tube, using the force of gravity. This allows the iron to produce steam continuously without the need to stop and refill the water reservoir.

Gravity feed irons are often used by professional tailors, seamstresses, and other textile workers, as well as by home users who frequently iron large amounts of clothing or other fabrics. They are also popular among quilters and other crafters who use steam to set their fabric.

One of the main benefits of a gravity feed iron is that it is convenient and easy to use. The water bottle can be filled quickly and easily, and it can be placed on the iron without the need to stop and refill the water reservoir.

Another benefit is that a gravity feed iron is more efficient than a traditional iron. Because the water is supplied continuously, the iron can produce steam more consistently and for a longer period of time.

When choosing a gravity feed iron, it's important to consider the steam output, heat settings, and the size and weight of the iron. It's also important to consider the size and shape of the water bottle and whether it will fit easily into the ironing area.
