The first continuous Hoffmann system kilns installed in Spain would have been in 1880, near Madrid. In 1900 there were already more than 4,000 kilns of this type, distributed throughout Europe, Russia, the Americas, Africa and even the East Indies. In 1904, an oven according to the patent of the British William Sercombe and based on the Hoffmann model began operating in Palmerston North, New Zealand. Hoffman kilns are still in use for brick production in some parts of the world, especially in places where labor costs are low and modern technology is not easily accessible.

This efficiency is a principal advantage of the Hoffmann kiln, and is one of the reasons for its original development and continued use throughout history. In addition to the inner opening to the fire passage, each room also has an outside door, through which recently fired brick is removed, and replaced with wet brick to be dried and then fired in the next firing cycle.

Each room is connected to the next room by a passageway carrying hot gases from the fire. In this way, the hottest gases are directed into the room that is currently being fired. Then the gases pass into the adjacent room that is scheduled to be fired next. There the gases preheat the brick. As

In a classic
Hoffmann kiln, the fire may burn continuously for years, even decades; in Iran, there are kilns that are still active and have been working continuously for 35 years. Any fuel may be used in a Hoffmann kiln, including
