These two machines are designed and manufactured by a company in Holland called Hoaf. They do not have ceramic plates, however, they have a jet system, which heats the tile and has an apron in here and with the reflection of the flame you create also infrared heat which is being used the same as a ceramic tile machine. However they are noisier and they do use more fuel as compared to the tile machines. The next larger model is a Hoaf 75, approximately 2.5 feet wide. It has 8 jets in there and its quite an efficient machine. You use approximately a tank like this in 45 minutes. Its designed for walkways, driveways, interlocking brick, and where you have a smooth, flat surface. Hoaf also produces machines on a larger scale, which can be mounted on a 3-point hitch or in front of a Bobcat attachment for agricultural use.
