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, which have district heating infrastructure, combine spacing heating (SH) and DHW together, with the aim of having a smart, energy efficient and environmentally friendly energy-consumption system, such as Denmark and China. Nevertheless, the development of DHW networks in these two countries differs significantly. This article detailed the comparisons in technical aspect: common preparation methods of DHW through district heating was introduced in China and Denmark with the analysis on temperature level, hygienic situation of DHW system, circular system, flow capacity and heat metering.
