Why be energy efficient?

Pressure gauge for industrial heat system.

Process heating and steam production are significant sources of energy use for Australian industrial companies and some commercial sub-sectors. For example, on a typical industrial site, boilers can account for 20–60% of energy costs and represent up to 35% of all potential energy efficiency improvements.1 Process heating and steam systems require large amounts of energy and can easily decline in energy efficiency because system losses are often difficult to measure or observe.

Energy use in process heating systems can be reduced by lowering demand for heating services, improving the efficiency of heat production, heat containment and improved heat transfer, and by recovering heat for reuse. Improved maintenance and management, such as using sensors and controls, can also help optimise performance. These measures reduce energy costs while increasing resilience to energy supply failure and providing improved workplace comfort.
