A heat concentrator device is provided for concentrating heat from a heat source for heating a container. The heat concentrator includes a heat concentrator body including a first side wall, the body including an upper concentrator end and a lower concentrator end, the body forming an inverted funnel shape. A lower concentrator opening is defined at the lower concentrator end, and an upper concentrator opening defined at the upper concentrator end, the lower concentrator opening being larger than the upper concentrator opening. A plurality of concentrator holes is defined in the side walls. At least one concentrator support extends from the lower concentrator end of the side walls, the at least one concentrator support resiliently biased inwardly, wherein the at least one concentrator support of the side walls is configured to directly engage the heat source, support the side walls, and orient the upper concentrator end toward the container.
