Why Unvented Cylinder Expansion Vessels Need Regular Attention

Expansion vessels are a vital component of your unvented hot water system. They're designed to absorb the increased water volume as it heats up, maintaining a stable pressure within the cylinder. Over time, the internal diaphragm can degrade, leading to a loss of pressure and improper functioning. This can put undue strain on your system, potentially causing damage and increasing the risk of leaks. Regular checks are essential to ensure your system is operating safely and efficiently.

The Preferred Gas Expansion Vessel Check: Detailed and Thorough

Our comprehensive expansion vessel check involves a visual inspection for any signs of damage or corrosion, a pressure test to assess the vessel's functionality, and a check of the connecting pipework and valves. We'll also inspect the pressure relief valve to ensure it's operating correctly as a crucial safety measure. If we identify any issues, we'll explain the problem clearly and provide you with a transparent quote for any necessary repairs or replacement.

When is it Time to Replace Your Unvented Cylinder's Expansion Vessel?

Several signs indicate your expansion vessel might need replacing:

  • Inconsistent hot water temperature: Fluctuating water temperature is a common sign.
  • Dripping pressure relief valve: A constantly dripping valve indicates over-pressure in the system.
  • Banging or knocking noises: These noises suggest pressure fluctuations and potential water hammer.
  • Low hot water pressure: Reduced hot water flow can be a symptom of a failing vessel.
  • Age of the vessel: Expansion vessels have a lifespan, typically around 5-7 years, even if no obvious issues are apparent, periodic replacement is recommended for safety.
    If you notice any of these signs, contact Preferred Gas for an inspection without delay.

High-Quality Expansion Vessel Replacements for Long-Lasting Performance

If a replacement is needed, we only use high-quality, WRAS-approved expansion vessels that are designed to withstand the demands of your hot water system. Our experienced engineers will ensure the new vessel is correctly sized and installed according to manufacturer guidelines and all relevant regulations.
