When Pump 5 fails in a heat recovery system, heat loss in the system is a significant consequence. Pumps in such systems are responsible for circulating water or a heat transfer fluid that collects and redistributes heat throughout the system. If one pump ceases to function, it can disrupt this circulation, leading to inadequate heat transfer. As a result, the system cannot effectively recover or maintain the desired thermal energy, causing an overall reduction in the system's capability to capture and utilize heat, which results in heat loss.

This heat loss can manifest in lower temperatures at the outlet, diminished efficiency of the entire heat recovery process, and possibly increased energy costs as the system compensates for the lost heat. Understanding this relationship between pump operation and heat retention is crucial for effective system design and maintenance.
