Cooker Hood - extraction to outside allowed?

    My bother lives in Continental Europe, he mentioned that because of their energy rating (A something) they weren't allowed to fit a Cooker Extractor Fan that vents to outside - they've a recirculating fan that isn't as effective. (So they have to open the windows when cooking something with strong smells :rolleyes:)

    anyone know if they are disallowed for A rated houses here?

    No. Not disallowed. They hurt the BER rating a small bit but easily compensated elsewhere (for the time being anyway).

    I always recommend extraction to the outside.

    for sure; no one bothers to change the carbon filters anyway...

    and like my bro pointed out they end up opening windows to compensate

    I think a good extractor with air quality sensors is ideal.

    Supposedly running for a few minutes beforehand to get air circulating correctly is important

    In airtight houses (passive levels at 0.6 ACH or below) they can affect and unbalance the MVHR (Mechanical Ventilation Heat Recovery) unit. It's important to have a stove with an external air feed if going this route otherwise the cooker extract can create a vacuum in the room sucking smoke into the room.

    So what is the solution then - an air inlet damper somewhere to bring in replacement air when cooking?

    Crack open the nearest window to the extractor during extraction. Close it afterwards. Works a treat.

    Heh, yeah.

    Also cooking with lids on saucepans, or adjusting heat to minimise steam etc would help. As would a splatter guard over frying pan with bacon etc

    I currently use an electric pressure cooker for curries and cook and vent outside (need external power socket and dry weather though)
