This patent describes a gas space heating unit for a dwelling or the like comprising a heat exchanger consisting of a porous elongated-shaped gas combustion device operative arranged to provide an incandescing surface and a source of hot combustion gases eminating radially therefrom and along the length of the elongated shape. A source of water is used in heat exchange with the hot combustion gases. A combination cylindrical housing is included, having an exit opening at one end and a first helical coil disposed in a clearance position in surrounding relation to and along the elongated-shaped combustion device and connected to the source of water for the flowing through the first helical coil of the water incident to establishing the heat exchange between the combustion gases and the water. A plug is located at the end of the cylindrical housing to block the flow of combustion gases centrally therethrough directly to the exit opening of the cylindrical housing so as to assist in producing gas movement radially outwardly therefrom into contact with the first helical coil. Finally the system includes means for urging a gas and air mixture to the surface of the combination device for supporting the incandescence thereon and also causing the production of hot gas from the mixture and the movement of the hot gas through the porosity thereof and radially outwardly from the elongated-shaped combustion device into heat exchange contact with the first helical coil.
