Can your business use heat recovery?Many companies are now collecting and reusing the wasted heat that’s generated bytheir operations.Some are using it to heat their premises, while others are using it to heat water, generatepower or preheat combustion air for ovens, boilers and furnaces. This recovered heat canbe used in a range of industrial processes. 43Regardless of how these companies reuse this wasted heat, the outcome is the same. Itreduces energy consumption and makes the company more energy efficient.Heat recovery ventilationIf your business has a lot of heat-generating processes, you may want to consider using aheat recovery ventilation system.A heat recovery ventilation system takes the cold air from outside, drawing it in througha heat exchanger. The heat exchanger captures the heat from warm, outgoing, stale air topre-heat the incoming outdoor air.In colder climates, these units help to retain heat inside a building. They can also reducethe heat load on cooling systems in warmer climates.The process is so efficient that it can recover up to 80% of the heat from the outgoingair. 44 If you need to regularly change over the air in your business, then this is a highlyefficient way to do so.Companies who distribute or install heat recovery ventilation systems can advise you onthe payback and cost-saving potential of these units.Heat ShiftersHeat shifters are basically a duct with a fan that transfers warm air from a heated roomto another unheated part of your business. They’re inexpensive to install and operate andcan transfer heat to another area up to 12 metres away. 4543 EnergyCut.info/heat-recovery-guide44 EnergyCut.info/heat-recovery-guide45 EnergyCut.info/heat-shiftersBack to Contents198
