Downdraft from stove

Hi, looking for a bit of advice if anyone can help.

We've a stove fitted at work, solid fuel, and depending on the wind direction we can't light it as it just fills the place up with smoke. The chimney is a twinwall pipe that goes out through the wall at 45degrees and up over the eave by about a metre. Just a chinaman hat cowl on top.

Any ideas if changing the cowl or adding a bit more pipe might help.
I'll only be making suggestions at work so might not have any feedback to give unless they try something.

Thanks.

We have exactly the same problem. Our stove is in the kitchen and we have the same twinwall flue as yourselves. It's all to do with physics!! Apparently cold air is heavier than warm air and this is why the smoke backs up, cold air in the flue stops the heat rising. My only advice is to light ur stove with small sticks and newspaper as these heat quicker and will push the cold air back up. We've actually kept our stove lighting constantly during the freezing weather so that we can keep the flue going. Hope this has been a bit helpful!;)

You can get some wind resistant caps for the tops of flues...
