A temperature regulator has two headers connected to both ends of a heat receiving tube in which gas flows. The heat receiving tube has a heating element at the outer periphery thereof and a mixer accommodated therein to cause turbulent flow of gas passing through the heat receiving tube. The headers each have fins radially attached thereto, thereby ensuring strength of the headers and improving heat exchange efficiency.

The invention claimed is: 1. A fluid heater comprising: a header; and a heat receiving tube having an outer periphery, the header and the heat receiving tube mutually communicating so that fluid flows therethrough, wherein the heat receiving tube has a heating element positioned on the outer periphery of the tube, wherein the heating element comprises a heating layer adapted to generate heat by electric supply, an insulating layer insulating the heating layer and the heat receiving tube, and a covering layer covering the heating layer, wherein the heat receiving tube has a plurality of the heating elements or the heating layers mounted on the tube, and wherein the heating elements or the heating layers have different electrical resistances depending on positions where the elements or the layers are mounted. 2. The fluid heater as defined in claim 1, wherein at least one of the heating layers is printed on the insulating layer. 3. The fluid heater as defined in claim 1, wherein at least one of the heating layers is composed of a plurality of heating parts mutually connected in parallel. 4. The fluid heater as defined in claim 1, wherein the heating elements or the heating layers each has electric resistance that varies with temperature. 5. The fluid heater as defined in claim 1, wherein the heating elements or the heating layers are mounted on the tube and arranged in a direction of gas flow. 6. The fluid heater as defined in claim 1, wherein the outer periphery of the heat receiving tube is evenly surrounded by at least one of the heating elements. 7. The fluid heater as defined in claim 1, wherein the heat receiving tube accommodates a mixer so as to improve heat exchange efficiency of a fluid. 8. The fluid heater as defined in claim 1, wherein the heat receiving tube has an inner surface, and wherein the heat receiving tube accommodates a mixer, the mixer being located in immediate proximity to the inner surface of the heat receiving tube. 9. The fluid heater as defined in claim 1, wherein the header has a fin attached thereto. 10. The fluid heater as defined in claim 1, wherein the header has a header body adapted to introduce gas thereinto, the header body having a fin attached to its outer periphery. 11. The fluid heater as defined in claim 1, wherein at least one of the heating elements is adapted to be activated by a direct-current power source. 12. The fluid heater as defined in claim 1, wherein the heating elements are mounted and arranged on a plurality of positions on the heat receiving tube in a direction of fluid flow therein. 13. The fluid heater as defined in claim 1 further comprising a plurality of the heat receiving tubes, each of which has one of the heating elements, whose output is individually controllable. 14. A fluid heater comprising: a header, and a plurality of heat receiving tubes, the header and each of the heat receiving tubes mutually communicating so that fluid flows therethrough, and being adapted to divide gas flowing through the header into the heat receiving tubes, wherein at least one of the heat receiving tubes has a heating element positioned on the outer periphery of the at least one tube and is adapted to generate heat by electric supply, wherein the heating element has different electric resistances depending on positions where the heating element is mounted on the at least one tube. 15. The fluid heater as defined in claim 14, wherein the heating element is composed of a plurality of heating parts adapted to generate heat by electric supply and mutually connected in parallel. 16. The fluid heater as defined in claim 14, wherein the at least one heat receiving tube has a plurality of the heating elements, mounted on the at least one heat receiving tube and arranged in a direction of gas flow, and wherein the heating elements have different electric resistances depending on positions where the elements are mounted on the at least one heat receiving tube. 17. The fluid heater as defined in claim 14, wherein the outer periphery of the at least one heat receiving tube is evenly surrounded by the heating element. 18. The fluid heater as defined in claim 14, wherein the at least one heat receiving tube accommodates a mixer so as to improve heat exchange efficiency of a fluid. 19. The fluid heater as defined in claim 14, wherein the at least one heat receiving tube has an inner surface, and wherein the at least one heat receiving tube accommodates a mixer, the mixer being located in immediate proximity to the inner surface of the at least one heat receiving tube. 20. The fluid heater as defined in claim 14, wherein the header has a fin attached thereto. 21. The fluid heater as defined in claim 14, wherein the header has a header body adapted to introduce gas thereinto, the header body having a fin attached to its outer periphery. 22. The fluid heater as defined in claim 14, wherein the heating element is adapted to be activated by a direct-current power source. 23. The fluid heater as defined in claim 14, wherein at least one of the heat receiving tubes has a plurality of heating elements that are mounted and arranged on a plurality of positions on the at least one heat receiving tube in a direction of fluid flow therein. 24. The fluid heater as defined in claim 14, wherein the at least one heat receiving tube has a heating element, whose output is individually controllable.
