Abstract: A terrace heater is disclosed, including a base cabinet intended for storage of a supply of gas, which is connected to a burner at the free end of a support part extending upright from the cabinet. On the upwardly-facing free end of the burner, there is a reflector including an annular first screen which has a lower edge and extends outwards and at an angle downwards over the periphery of the burner for an inclined and downwardly-directed reflection of heat emitted from the burner along the edge of the reflector. Along only a part section of the circumference of the lower edge of the first screen and extending downwards from the edge, there is a second screen part oriented in a substantially vertical manner, the part section constituting between 20° and 340° of the circumference of the first screen.
