Yet a significant proportion of that energy is effectively wasted, released into the atmosphere as excess heat from processes, equipment, or ventilation systems. At Sigma Engineering, we approach heat recovery not just as an efficiency upgrade, but as a financial opportunity. When implemented correctly, recovering and reusing heat can reduce operational costs, improve system performance, and deliver...]]></description><link>https://www.sigmaepd.com/post/why-heat-recovery-makes-financial-sense</link><guid isPermaLink="false">69f1db35829c52805ba87f3f</guid><pubDate>Wed, 29 Apr 2026 10:22:03 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/9a6557_e245d2fcb4bc477e991e6c0f1e440ab9~mv2.png/v1/fit/w_1000,h_768,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Jack Spencer</dc:creator></item><item><title><![CDATA[Signs Your Kitchen Extract System Is Underperforming ]]></title><description><![CDATA[A reliable kitchen extract system is one of the most important parts of any commercial kitchen.

Poor air quality, lingering odours, excess heat or a build-up of grease can all have a direct impact on people’s comfort and safety.  For many commercial buildings, an extractor fan is essential.

"Just open the window". It's a common 'solution' in kitchens, bedrooms, offices and classrooms. But to tell you the truth, it doesn't do the job. Cracking the window in an office where the air feels suspiciously stuffy by 10 am doesn't fix your problem and is definitely not practical. Cracking open a window is not a ventilation strategy; it's a quick fix (and a guaranteed complaint from whoever's parked nearest to the window).
