According to one aspect of the presently disclosed subject matter, there is provided a heating device including: top and bottom walls, front, rear and side walls extending therebetween, all forming therebetween an interior of said heating device, said front wall being made of a see-through material; and a back panel made of a ceramic non-fiber material, such as porcelain, and mounted to the bottom wall and the top wall so as to be spaced from the rear wall and so as to conceal the rear wall at least when seen through the front wall.

A fireplace system having one or more elements that operate to reduce the energy of acoustic signals propagating through the fireplace system before they are broadcast from a firebox of the fireplace system into a room within which the fireplace system is located. In some examples, a powered exhaust evacuation system is coupled to the fireplace system and an acoustic attenuation element of the fireplace system operates to reduce the acoustic signal of the powered exhaust evacuation system as it propagates through the acoustic attenuation element.

A small stove assorted with smokeless combustion of combustible solids/semisolids, a stove core and a shape of briquette are to ensure that a cylindrical briquette stack is quickly ignited in a smokeless state. A section A stove core inner ring and a flame concentrator are made of a selected high-whiteness aluminum silicate fiber with superior thermal insulation/resistance effects, and are processed for, e.g., blocking the micropores inner circumferential surface, and a stove core outer ring is made of cheaper foam glass, foam ceramic or calcium silicate modules. An underlying briquette with a concave top is designed to enable an easy, convenient and fast alignment of vent holes. The overall cross-sectional area of the vent holes is expanded by 30%-50% as compared with the area of the anthracite briquettes with the same diameter, and the inner ring vent holes are mainly expanded.
