The NEW Flue In Void Solution - No Hatches Required


Installation of gas boiler flue inspection hatches will not always offer the best nor practical solution to enable Gas Engineers to confirm that a flue system is complete and intact.

Systems capable of monitoring a void containing a concealed flue for the presence of CO which, on activation will shut down a faulty boiler are the Industry Flues In Voids Working Group agreed solution for property owners who do not have or do not want to have inspection hatches installed.

How does it work?

How does it work?
An ordinary carbon monoxide alarm cannot be used in the place of inspection hatches.
The NoCO wireless system is the first and only alternative to inspection hatches and is compatible with any make or model of boiler.

  • New & Approved Alternative to Flue Inspection Hatches
  • European CO Alarm Standard EN 50291:2010
  • System continuously monitors flue voids and rooms for CO
  • Automatic Boiler Shut Off if unsafe CO levels are detected
  • Visual and Audible Alarm
