Correct Pump Position with an F&E Tank | Circulation Pump Explained

In this video, we take a real question from one of our friends, subscribers, and fellow engineers about the correct circulation pump position in a heating system with an old F&E (Feed & Expansion) tank. Many systems are set up incorrectly, which can cause air locks, poor circulation, and constant breakdowns. Here, I explain exactly where the pump should be located, why position matters, and how it affects the whole heating system. By following the correct configuration, you’ll avoid common issues and keep your system running smoothly. We’re here to help engineers, subscribers, and homeowners who want to learn more about heating system design and troubleshooting.
