Expansion tanks play a crucial role in maintaining pressure stability in closed-loop HVAC and hydronic systems. But what happens when they are neglected or improperly sized? The result can be catastrophic, as seen in this video.
🔴 Common Reasons for Expansion Tank Failure:
✅ Wrong Sizing – If the expansion tank is too small, it cannot accommodate thermal expansion, leading to overpressure and potential rupture.
✅ Neglected Maintenance – A failed bladder or loss of pre-charge pressure can make the tank ineffective, causing system pressure fluctuations.
✅ Improper Installation – Incorrect location or missing safety devices (like a pressure relief valve) can contribute to failures.
💡 How to Prevent Such Failures?
🔹 Always ensure proper tank sizing based on system volume and temperature changes.
🔹 Periodically check pre-charge pressure and bladder condition.
🔹 Work with experts to select and install the right tank for your system.
