This paper synthetically presents the steps and the main elements to be taken into account by construction installation engineers when they design circulation pipes for domestic hot water. By this paper, we propose a new method concerning the calculation of the domestic hot water circulation pipe. Basically, after determining the circulation flow, the diameter of the circulation pipe is determined based on the economic speed of the most disadvantaged section, and for the remaining sections, the diameters are determined depending on the pressure available at the branch points. The method proposed by the author in this article may be used in order to design domestic hot water circulation pipes, in case of secondary thermal networks made with pre-insulated pipes directly embedded in soil.
