What type of energy does a heat recovery system primarily aim to conserve?

A heat recovery system primarily aims to conserve thermal energy. These systems capture excess heat that would typically be wasted during various processes, such as in HVAC systems or industrial operations, and repurpose it for heating water or air or other beneficial uses. By recovering this thermal energy, the system reduces the amount of energy needed to maintain desired temperatures in buildings or processes, leading to increased efficiency and reduced energy costs.

The focus of a heat recovery system is specifically on the management and reuse of heat—hence the emphasis on thermal energy—not on electrical, chemical, or mechanical forms of energy. Understanding this concept is crucial in fields related to energy efficiency and sustainable building practices, as it highlights the importance of optimizing energy usage and minimizing waste in both residential and commercial settings.
