Abstract: The heater includes a cylindrical tube made of mechanically strong and elsatic electromaterial, such as metal with multiple separated sections. Electrically insulated layer, such as ceramic, is applied on its external surface with the exception of one open section. Then electrically resistent heaters are applied over the insulated sections which are electrically connected by one of their ends to the underlying electrically conducting section. The electric conductor is connected to the negative terminal of a supply source. The other end of all heaters is fabricated in such a way in order that it should be connected to the positive terminal of the source. Electroresistant heating circuit shall be made, respectively, where the tube shall serve as a common terminal for all the heating elements. The tubular heater can contain an open endpiece from which multiple wider sections can spread. On each of them a heating layer can be separately applied. In another alternative a heater can be applied on every other wider section. The wider sections having no heaters shall act as barriers for minimizing the separation of the produced scents outwards and as heat absorbers for the heaters in the adjacent sections. 49 claims, 14 figures
