The invention discloses an electric resistance heat element for a heating device for heating a flowing gaseous medium. The invention relates to an electrical resistance heating element for a heating device, with at least one flow canal through which the gaseous medium is able to flow from a canal inlet side to a canal outlet side of the resistance heating element, and with at least one heating resistor that extends essentially in the direction of the flow canal, with the medium flowing past the heating resistor and being heated in the process. The heating resistor is rod-shaped and produced from an electrically conductive ceramic material. The electrical resistance heating element is intended for installation in a heating tube into which air, for example, is blown at one end. The heated flow of air exits from the other end of the heating tube.

This invention discloses a liquid heating device, core of the said device and a fabricating method thereof. Said liquid heating device includes: a core arranged a channel for flowing the liquid inside it and attached a water inlet level and a water outlet level; at least a thermal diffusion part having a first face and a second face. Said thermal diffusion part is fixed in the center of the coreand the first face is jointed with the core; at least a heating components fixed on the thermal diffusion part and jointed with the second face of the thermal diffusion part, either the heating components or the thermal diffusion part acts as a independent part or formed a whole inseparable body with the core; a case for strengthening purpose. The advantage of this invention is that an even heating process can reduce the risk of overheating of the heating components. Said thermal diffusion part can protect heating components from overheating when there is not enough liquid in core, in addition, promoting the liquid to be discharged easily and at the same time, increasing the heat transfer efficiency from the heating components to the liquid in the core.
