Cooker hood breeze
In our kitchen we have a perfectly ordinary cooker hood vented outside. Trouble is, there is quite a draught from it. It exits into the gap between our house and our neighbours' - which can be pretty windy. Fine when cooking, but makes the whole kitchen a bit chilly in the winter.
Is there a simple (but effective) way of reducing airflow when we are not using it? Obviously we could shove a rolled up newspaper in the hole - but that is hardly convenient! |

Does it have "back draft shutters" fitted? They are thin light plastic spring loaded flaps (usually a pair, each semi circular) usually mounted immediately before the ducting connects to the fan output spigot. They are pushed open by airflow from the fan being on, then when fan is off they shut due to their springs. You usually hear them as they "slap" shut after the fan is switched off... When switched on or off, it makes no noise (other than the motor). I didn't fit it - so will check out the documentation and have a look. Thank you. |

You could try a cowl vent or flap vent as shown he https://www.screwfix.com/c/heating-plumbing/air-vents/cat840496 Either can help, but aren't perfect. The cowl vent can let some air in as it's still open to the outside. The flap vent is closed, but the one I used would make a noise as wind rushed past it and pulled it open, allowing it to fall back when the wind dropped, and make a tapping noise. I had to fit a sort of restrictor so it could open only a cm. -- Jeff |

I should have gone out and checked what is visible on the side! :-) Because of the arrangement of houses here, we virtually never even look up that side. (Not that it is a problem to do so!) Will check in the morning. Thank you. |

You can get external versions as well - ours has three horizontal shutters, each hinged from its top edge. They are not as good though, ours sometimes blows up and gets one trapped behind the one above, stopping it closing properly. SteveW |

If it hasn't and it isn't easy to fit one a less effective but useful alternative is a louvred vent on the outside wall with slats that close up when there isn't any outflow.

The one on our bathroom seemed especially prone at one stage until I changed it. |

There are gravity closed airflow opened shutters - you might have one that's stuck open. They blow open in wind and stick open on occasion. Then there are solenoid & wax motor powered flaps, they're much better, staying shut when they should. Solenoids go clunk when they operate, wax motors are silent. Both require power. NT |

In a domestic cooker hood the grease filter is usually the first stage of filtering.

Nothing happens in strong winds, no leaks of warm air in the house with it off. It does open with a hell of a bang when you turn the fan on, but you soon get used to that. And two great big headed screws and the whole thing comes off and all the plastic and none of the electrics comes off and its fine in the dishwasher. |
