FAQs

What is the primary function of an expansion vessel?

An expansion vessel absorbs the increased volume of water in a heating or potable water system when it heats up, preventing excessive pressure build-up and protecting system components.

How often should the pre-charge pressure be checked?

It is recommended to check the pre-charge pressure at least once a year, or more frequently if system pressure issues are observed. Ensure the system is depressurized before checking.

Can this expansion vessel be used for both heating and potable water?

Yes, the Altecnic ERES ER-PV19 is rated for potable water and is also suitable for use in closed-loop heating systems.

What is the correct pre-charge pressure?

The correct pre-charge pressure is typically set to match the system's cold fill pressure. Always consult your system's manual or a qualified professional for the exact setting.

Do I need a professional to install this vessel?

While basic plumbing knowledge can suffice for some, it is highly recommended to have a qualified plumber or heating engineer install the expansion vessel to ensure correct integration and safety.

What does 'potable water rated' mean?

'Potable water rated' means the vessel is constructed from materials safe for contact with water intended for drinking, cooking, and other domestic uses.

Troubleshooting

System pressure is too high or fluctuating wildly.

Check the air pre-charge pressure of the expansion vessel. It may be too low or lost over time. Re-charge to the correct pressure when the system is depressurized.

Expansion vessel appears to be leaking.

Check the valve at the base of the vessel for leaks. If the vessel itself is damaged, it may need replacement.

No noticeable difference in system pressure.

Ensure the vessel is correctly installed in the system and that the pre-charge pressure is set appropriately for the system's cold fill pressure.

Pros and Cons

Pros

  • Effectively manages thermal expansion in water systems.
  • Durable construction ensures a long service life.
  • Includes a bracket for straightforward installation.
  • Suitable for potable water applications, offering versatility.
  • Helps to maintain consistent system pressure.

Cons

  • Requires correct pre-charge pressure setting for optimal function.
  • May require professional installation for those unfamiliar with expansion vessel systems.
  • Bulkier than smaller capacity expansion vessels, potentially limiting placement options.
  • Specific system compatibility should be confirmed before purchase.

Setup, Compatibility & Care

Setup:

  1. Isolate the System: Ensure the heating or potable water system is depressurized and isolated from the mains supply.
  2. Mount the Vessel: Use the provided bracket to securely fix the expansion vessel to a solid wall or suitable structure, ensuring easy access for future checks.
  3. Connect to System: Connect the vessel to the system pipework using appropriate fittings. Ensure the connection point is suitable for managing expansion.
  4. Check Pre-charge Pressure: Before fully integrating, verify the air pre-charge pressure using a tire pressure gauge. This should typically match the system's cold fill pressure (consult system design or installer recommendations). Adjust if necessary using a Schrader valve.
  5. Fully Integrate: Once the pre-charge is set, the system can be repressurized, and the vessel will begin its function.

Compatibility:

  • Suitable for closed-loop heating systems and potable hot and cold water systems.
  • Ensure the system pressure and temperature ratings are within the vessel's specifications.
  • Always consult with a qualified plumber or heating engineer to confirm suitability for your specific installation.

Care:

  • Periodically check the air pre-charge pressure (at least annually) to ensure optimal performance. The system must be depressurized before checking.
  • Inspect the vessel for any signs of corrosion or damage.
  • Keep the area around the vessel clean and free from debris.
