Franklin stoves, also known as Pennsylvania fireplaces, were invented by Benjamin Franklin in the 18th century. These stoves were designed to be more efficient than traditional fireplaces, with a shape that allowed for better airflow and heat distribution. The original design featured an open-face, cast-iron box that could be placed in the middle of a room and used to heat the space.
Today, Franklin-style stoves are still produced by some manufacturers, and many antique Franklin stoves can be found for sale. However, modern building codes may restrict their use in some areas, as they may not meet modern safety standards. If you are interested in purchasing or using a Franklin stove, it is important to research local regulations and safety requirements before doing so.
