• In this video, This Old House plumbing and heating expert Richard Trethewey explains how to choose a carbon monoxide detector.


    1 Simplest, most affordable carbon-monoxide detector plugs into an electrical outlet.
    2 Battery-powered plug-in models continue to operate during power outages.
    3 Combination units detect smoke and carbon monoxide, and are hard-wired into the home's electrical system.
    4 Unlike smoke detectors, which must be ceiling-mounted,
    carbon-monoxide detectors can be mounted to a baseboard or set on a bookshelf.
    5 Digital models constantly display the carbon monoxide levels in the room.
    6 Recommendation is to place one carbon-monoxide detector on every floor in the home; minimal requirement is one detector outside of every bedroom.
