Heat recovery is a process that captures and reuses waste heat generated from industrial processes, buildings, or vehicles. This recovered heat can be used for various applications, such as heating water, space heating, or even generating electricity. By utilizing this otherwise lost energy, heat recovery systems improve overall energy efficiency and reduce fuel consumption. Common technologies for heat recovery include heat exchangers, heat recovery ventilators, and combined heat and power (CHP) systems. These systems can significantly lower energy costs and decrease greenhouse gas emissions, contributing to a more sustainable and environmentally friendly approach to energy use.
