Do you have smoke billowing out of your stove every time you open the door to refuel? How about smoke lingering around in the firebox instead of being drawn quickly up and out the chimney? It is frustrating and it can begin to cause issues, especially for those with breathing problems, but before you give up on your stove, here are some tips that can help rectify the situation.
During wintry weather, when temperatures drop, a pocket of cold air becomes trapped in the chimney, if there isn’t a flow of air. So when you come to light your fire you’ll find the denser cold air forces the smoke back down the chimney. Sometimes a new fire just isn’t hot enough to force the cold air out.
To combat this, pop a firelighter, or roll of newspaper on top of your wood. This will put your flame’s heat directly up the chimney. This should give your chimney the heat it needs to clear the blockage of cold air. Read our blog post and watch the video on this here.
However if the issues persists you can try a few other tips:
Clean your chimney
Clean your chimney at least once or twice a year depending on usage to help the draw.
Open the door slowly
You may simply be opening the door too fast. This action can draw the smoke out into the room. When you open the door, leave it ajar for a second or two before opening fully. This should allow for the pressure in the firebox to equalise and continue to send smoke up the chimney.
Burn drier wood
Unseasoned wood will produce a lot of smoke. High levels of moisture can cause a build-up of creosote in a chimney, which can be dangerous. The fire’s energy is spent trying to boil the water out of the log, so not only do you get a lethargic, smoky mess rolling around in the firebox, you won’t get the firebox up to a sufficient temperature to shift the cold air blockage. Consider buying a moisture metre, kiln dried wood and bringing logs in from the cold a few hours before you burn them to warm them up and prevent condensation.
Improve the chimney’s draw
A rotating aspirator cowl will assist the draw of the chimneys when it is windy. The rotating cowl will help move the cold air up and out of the chimney. This helps to keep air moving through the house in the correct direction.
Sometimes smoke may be coming out of your stove because of a downdraft. Your chimney not being set high enough above the roof, trees or other buildings. A chimney pot can extend the height of the chimney. Meanwhile, similar to an aspirator cowl, an anti-downdraft cowl prevents a downdraft but doesn’t improve the draw. It is worth figuring out which of this you need before you purchase.
Add a draught booster
This new technology sees a fan built into a cowl that sucks air up the chimney. It is worth noting that this cowl will require regular maintenance to prevent a build-up of ash deposits. A build-up can cause it to stop working. However it will greatly aid in removing the cold air trapped inside your flue or chimney. This is especially relevant if your flue is shorter than recommended.
