A heater includes a base formed with a receiving space for receiving a fuel material that is to be combusted, and a heating unit. The heating unit includes: a flow guide component disposed on the top side of the base and having a through hole axially aligned and in communication with the opening, and at least one air passage communicated with the through hole and permitting air externally of the flow guide component to flow therethrough into the receiving space via the through hole and the opening; and a heat-radiating pipe disposed to extend upwardly from the flow guide component and disposed to surround the through hole and permitting flow of flue gas resulting from combustion of the fuel material in the receiving space therethrough. |
