Product information

Description

The FLAMCO Contra Flex Standing Expansion Vessel 35L Red for Central Heating 3bar 26343 is a reliable pressure vessel engineered for closed central heating systems. With a total capacity of 35 liters, this standing expansion vessel absorbs the volumetric expansion of water caused by temperature fluctuations, maintaining stable system pressure and protecting installation components from excessive stress.

Advantages

This expansion vessel features a durable construction designed to withstand the operational demands of residential and commercial heating setups. Its standing orientation allows for straightforward integration into existing boiler rooms or technical spaces. The pre-charged pressure vessel ensures consistent performance, reduces the frequency of pump cycles, and extends the overall lifespan of the heating installation.

Suitable for

  • Residential central heating installations
  • Small commercial heating systems
  • Closed water-based heating circuits
  • New construction and system modernization projects

When it may not be suitable

This model is not suitable for domestic hot water supply systems or potable water installations, as it is specifically designed for closed central heating circuits. Additionally, systems requiring a higher working pressure than the specified maximum limit or a larger water volume capacity will require a different vessel size or specification.

Key specifications

  • Capacity: 35 liters
  • Maximum working pressure: 3 bar
  • Application: Central heating systems
  • Design: Standing vessel
  • Color: Red

How to use

The vessel must be installed by a qualified heating technician in accordance with local regulations and manufacturer guidelines. It should be connected to the return pipe of the central heating system, close to the circulation pump or boiler. Ensure that shut-off valves and safety valves are installed correctly to allow for future maintenance and pressure checks.

What to consider before purchase

  • Verify that the 35-liter capacity matches the total water volume and thermal output of your heating system.
  • Check that the maximum pressure rating of 3 bar is compatible with your boiler and safety relief valve settings.
  • Ensure there is sufficient physical space in the mechanical room for a standing vessel installation.
Usage recommendations: Regularly inspect the expansion vessel pressure and overall condition at least once a year during routine heating maintenance. Avoid exposing the red exterior finish to corrosive environments or mechanical damage to preserve the integrity of the vessel.
