Countries in subtropical areas always overlook the issue of building hot water supply systems due to the short winter and high average temperature. However, the hot water supply system is still identified as requisite residential building equipment in subtropical countries such as Taiwan. Previous research with an overview of residential water usage revealed that building hot water consumes a great amount of energy and some critical problems are disregarded. This paper focuses on the residential building hot water supply system using Taiwan as a subtropical area example. Several significant hot water supply system features are presented with the quantitative parameters from Taiwan.
