• You need inspection hatches, its in the manufacturers instructions and haven't heard its changed to CO detectors.

  • I read about monitoring systems on the gas safe register

    I have heard that there could be alternatives to having hatches fitted. Is this true?
    Visual examination checks by engineers via inspection hatches is currently the preferred method recommended by the industry guidance that explains how to judge that a flue is working safely and effectively. However, where inspection hatches are not practicable industry has developed a safety system which is able to monitor the void for the presence of carbon monoxide and which cause the boiler to shut down if it is detected.

    It looks like Baxi do a system but I can't seem to find details beyond this launch release from 2013

    Am I right in saying that inspection hatches are only needed at joins in the flue? So if the flue starts in the large cupboard where it is easily visible and then runs straight through the ceiling void/boxed in section to the exterior wall i wouldn't need a hatch?

  • How much will inspection hatches cost me?
    It will vary from property to property. It is recommended that hatches are at least 300mm x 300mm and wherever possible, be positioned within 1.5m to the side of any joint in the flue system. Therefore, some properties will only need one hatch, while others may need more.

    We could in theory take our inspection hatches out now as we replaced the coupled flue with a single pipe earlier this year.

  • If it was in the ceiling void/boxed in you only need them at the joint and has to be adequately supported in the void too.

    It’s all I pretty straight forward if I’m honest but I’ve never heard of the other system or been asked for it or seen anything in the gas magazine that it changed
