<p>The device has a burner (21), and a cylindrical housing enclosing a tubular heat exchanger (20) that comprises a flow channel (34) for a heat carrier. A heat pipe for generating thermal radiation influencing on the heat exchanger is arranged in an inner area enclosed by the heat exchanger, where the heat pipe is lighted by the burner. The heat pipe has a gas mantle made from heat-resistant fabric, braided fabric and/or lattice, where the heat-resistant fabric, braided fabric and/or lattice of the mantle is formed by high temperature-resistant fibers made from metal or ceramics.</p> |
