An electric space heating apparatus consisting of a plurality of sections having box-like portions which by means of middle pieces are interconnected in such a way that the apparatus can extend along all the walls of the room and the zig-zag electric heating elements in the apparatus sections can be fed continuously through the complete apparatus, the apparatus being adapted to deliver the heat to the space by approximately 65-75 per cent radiation and approximately 25-35 per cent convection to circulating air, said apparatus can be easily mounted by persons without special education and authorization.

I claim

1. A baseboard electric heating apparatus of the type which is adapted to be mounted at the floor along the walls in a room which is to be heated and to constitute a baseboard along the walls of the room, said apparatus including a plurality of elongated apparatus sections, each apparatus section comprising a box-shaped housing in which an electric heating element is mounted, each apparatus section having air inlet and air outlet openings for the flow of air therethrough by convection and the exposed outer surface of each apparatus section defining a heat radiating surface whereby heat from the heating element can be delivered to the room partly by radiation from the exposed surface and partly by convection via air circulating through the apparatus section, said plurality of apparatus sections being interconnected end-to-end and being mounted at the floor as a baseboard along all of the walls of the room to be heated whereby the heating apparatus surrounds the space to be heated, connecting means interconnecting said heating elements of the respective sections in such a way that power can be fed to the heating elements from one end of the interconnected array of apparatus sections, said plurality of apparatus sections so constructed that approximately 65-75 percent of the heat therefrom is delivered by radiation and approximately 25-35 percent is delivered by convection, said individual apparatus sections comprising a rectangular inner part having a plane, in mounted position vertical, main portion and an upper and lower flange portion projecting away from the wall in the room, said inner part carrying eye-like members for supporting said heating element in said housing and supporting and distance members which are adapted to mount the main portion at a predetermined distance from the wall of the room and to engage mounting means on the wall of the room, and further, an outer part consisting of a plane main portion of the same shape as the main portion of the inner part and having upper and lower flange portions projecting towards the main portion of said inner part and which extend over and under the flange portion of the inner part, respectively, and have bent rim portions engaging the rear side of the inner part, at the top and the bottom of the main portion of the outer part, horizontal rows of air holes being provided to form said air inlet and air outlet openings.
