Question 100General Subjects - 1st Asst/Chief
70% to passWhat design feature is used to minimize potable water wastage associated with hot water distribution piping for a potable water system?
AUse of storage type hot water heaters only.
BUse of hot water recirculation loops.
CUse of hot water heaters with multiple heat sources.
DUse of instantaneous type hot water heaters only.
AI Explanation
The correct answer is B) Use of hot water recirculation loops. Hot water recirculation loops are a design feature used to minimize potable water wastage associated with hot water distribution piping. By circulating the hot water through a loop, the water is kept hot and ready for use, reducing the amount of water that needs to be run to reach the desired hot water temperature. This helps conserve water and energy compared to systems without recirculation. The other options, while potentially related to hot water systems, do not directly address the issue of minimizing potable water wastage through hot water distribution.
