Our partner, Renewable Hub, are keen to spread the word on an often-forgotten energy saving technology. Here’s what they have to say:
If you’ve ever walked into a warehouse or factory in winter and felt freezing on the ground floor but roasting near the roof, you’re not imagining it. It’s a common problem known as thermal stratification – where warm air rises and stays trapped at ceiling level, while the people who actually need the heat are left feeling cold.
The result? Heating systems work harder than they need to, energy bills climb, and you’re paying to heat empty roof space.
One simple solution that often gets overlooked is a de-stratification fan.
Unlike a standard fan that’s designed to cool people down, de-stratification fans work by gently circulating the air within a building. During the winter, they push the warm air that’s collected at roof level back down into the occupied space, creating a more consistent temperature throughout the building. This means your heating system doesn’t have to work as hard to keep staff comfortable.
In the summer, they continue to provide benefits by improving air circulation and helping to prevent heat from building up in one area. This reduces hot spots and can ease the workload on air conditioning systems, allowing them to cool spaces more efficiently while reducing overall cooling costs.
The technology itself is simple, but the results can be significant. Depending on the building and how it’s currently heated or cooled, organisations can typically see 25% savings on cooling and 35% heating costs, while also improving comfort for employees and reducing unnecessary carbon emissions.
They’re particularly effective in buildings with high ceilings, including warehouses, manufacturing facilities, distribution centres, sports halls and retail units, where conditioned air naturally rises and is often wasted. Because the fans use very little electricity, the energy they consume is usually outweighed many times over by the energy they help save. It’s a straightforward upgrade that can deliver long-term operational savings without major disruption.
With energy prices continuing to put pressure on businesses, it’s worth looking beyond the obvious efficiency measures. Sometimes the biggest opportunity isn’t replacing your heating or cooling system – it’s making better use of the conditioned air you’re already paying for. Improving air circulation can increase comfort, reduce energy waste and deliver meaningful savings year after year.
If you’re wondering whether de-stratification fans could benefit your site, we’d be happy to help. At Renewable Hub, we offer free, independent consultations to help businesses identify practical opportunities to reduce energy consumption, lower operating costs and improve efficiency. Get in touch with our team to find out if de-stratification could be the right fit for your building.
