Abstract: This invention concerns a heating pipe for panel heaters disclosed on walls, ceilings or floors to heat a room. The pipe is essentially constructed of a pipe itself, an electric heating wire running through it and aluminum granules stuffed between the two. Because of the simple structure, the production, the installment and the maintenance costs are cheap; as a matter of course, there is no additional need of a circulation pump for heating media and safety devices to watch the leak of heating media or the break of the pipe. Moreover, because spherical aluminum granules are closely packed, the heat conductivity is very good, which minimizes the heat loss and reduces the time to heat up a room. Also, the heat capacity is so small that frequency room temperature control by means of an automatic on-and-off mechanism has becomes possible.
