Abstract

Regardless of where they are in the world, people depend on a reliable and sufficient supply of domestic hot water (DHW) for daily use. Some countries that have district heating (DH) infrastructure, such as Denmark and China, combine spacing heating (SH) and DHW together, with the aim of having a smart, energy efficient and environmentally friendly energy-consumption system. Nevertheless, the development of centralized DHW (CDHW) systems in these two countries differs significantly. This article details the challenges China’s CDHW system is currently encountering and proposes to apply the flat station concept to improve China’s CDHW system. Meanwhile, the technical advantages of the Danish CDHW, which would benefit China, are analyzed. Overall, from a technical
point of view, the flat station concept is not only in line with China’s current DH conditions but would compensate for some technical defects of the existing CDHW system.
