Product information

Description

The Meibes Airfix E DHW 25/4.0 Expansion Vessel for Potable Water 25 Liters 10 Bar is engineered to manage volume expansions in domestic hot water systems and potable water installations. By absorbing excess water volume generated during heating cycles, this vessel maintains stable system pressure and prevents unnecessary discharge from pressure relief valves. Built for reliability, it integrates seamlessly into residential and commercial setups requiring precise pressure control.

Advantages

This expansion vessel effectively protects domestic hot water installations by absorbing thermal water expansion, which significantly reduces wear and tear on system components. It helps prevent water loss through pressure relief valves, contributing to overall water and energy efficiency. The robust construction ensures a long service life, maintaining stable operating pressures in daily use while safeguarding the plumbing infrastructure against pressure surges.

Suitable for

  • Potable water installations and domestic hot water systems
  • Booster systems and pressure management setups
  • Residential buildings and small commercial properties
  • Closed water systems requiring thermal expansion control

When it may not be suitable

This device is not designed for use with non-potable closed heating circuits or solar thermal systems that require high-temperature specialized fluids. It is also unsuitable for systems where the maximum operating pressure or capacity requirements exceed the technical limits of a 25-liter vessel rated at 10 bar.

Key specifications

  • Capacity: 25 liters
  • Maximum working pressure: 10 bar
  • Application: Potable water systems and domestic hot water installations
  • Function: Absorbs water volume expansions caused by temperature changes

How to use

Installation should be performed by a qualified professional in accordance with local plumbing and safety regulations. The vessel is integrated into the potable water or domestic hot water circuit, typically on the cold water inlet side of the water heater, ahead of any check valves. Ensure proper mounting support and check that the pre-charge pressure corresponds to the system requirements prior to initial operation. Routine inspections should be conducted periodically to verify membrane integrity and system pressure levels.

What to consider before purchase

  • Verify that the 25-liter capacity matches the total volume and heating requirements of your specific water system
  • Check that the maximum 10 bar pressure rating is compatible with your installation parameters
  • Ensure adequate physical space is available for mounting and future maintenance access
  • Confirm compatibility with potable water standards and local plumbing codes
Usage recommendations: Regularly monitor the pre-charge pressure and inspect the vessel annually to ensure optimal performance and extend the lifespan of your domestic hot water installation.
