Optimal placement of the SpiroTop air vent

A float air vent such as the SpiroTop is essential to prevent air accumulation in an installation. Free air can cause blockages in the pipes that interfere with the operation and efficiency of the system.

Common locations where air accumulation occurs are:

  • The highest point of the installation.
  • Boilers, heat exchangers and buffer tanks.

By strategically placing SpiroTop air vents in these places, you prevent air accumulation and ensure stable and efficient operation of the system.
