Heat recovery is the collection and re-use of heat lost from a process. This can help to reduce the energy consumption of the process itself, or to provide heat for other processes.
The steam and high temperature hot water boilers technology overview (PDF) and low temperature hot water boilers technology overview (PDF) give an introduction to the main energy saving opportunities for businesses.
Identify and quantify heat wastage – energy savings of up to 30% can be made for a particular process by recovering heat and using it for another purpose
Make sure all process machinery is switched off (or ramped down) when a process is not operating
Heat-recovery devices need regular maintenance to work at their most efficient levels
