<p>The heating device (10) has a thermally conductive plate-shaped block (12) with two passages (18) through the block, where the passages are separated from each other. Each passage has the form of a longitudinal hole with two openings. A curved pipe element (14) with two legs (20) facing in the same direction are provided. Each leg is arranged in a passage and a heating element is arranged on the surface of the plate-shaped block. The two passages are arranged parallel to each other. The pipe is bent in U-shape. An independent claim is included for a device for supplying a protective space with gas, particularly breathing gas with a pressure reducing valve.</p> |
