Good practice guide for operating wood burners and open fires
Many homes now burn wood as a source of heat and enjoyment. It’s economical, renewable and can heat your home well, if used properly. A wood burner or open fire that isn’t being used properly can produce excessive smoke, which wastes energy, and creates air pollution. Inefficient wood burners and open fires can also be fire hazards. While the efficiency of wood burners will vary, open fires will actually draw heat from your home and are very inefficient.
This page offers plenty of information on how to safely enjoy your wood burner, get the best heat out of your firewood and decrease the smoke. By changing the way you use your fire you can make major pollution reductions and potentially prevent complaints from neighbours.
Why keep the air clear?
Smoke pollution affects everyone. It is harmful to the health of wood burner users and the health of others in the community. People who are more at risk are babies and very young children, those suffering from existing cardiac or respiratory conditions (such as asthma), those with vascular complications from diabetes and frail, elderly people.
Excessive smoke from fires is unpleasant and detracts from people’s well-
Basic steps to remember when lighting a fire, make sure you:
Once the fire is alight, make sure you:
How smoky is your chimney?
In a well-
An efficient fire will have bright swirling flames and red glowing embers with little or no smoke coming from the chimney. It may take some practice to get the cleanest burn from your chimney.
The chimney/flue is an important component of the wood burner installation. It needs to be long enough to draw sufficient air for proper combustion of the fuel and high enough to let smoke and gases disperse.
Collecting and storing firewood
Good quality firewood is the key factor to have a clean burning fire. The wood needs to be dry and well seasoned. Think ahead and get your wood supply in the summer. Freshly cut wood needs to be stored for 8-
How to burn smarter
Here are some tips to keep your fire burning efficiently so you get the best value from your firewood and really cut down the smoke.
Wood burner size and installation
Most wood burners perform best at or close to their maximum output. If you often run your burner at low settings (damped down), your burner may be oversized for your room. If you are buying a new wood burner, or replacing one, it is important to ensure it is the right size for the rooms that are being heated and that it meets emission standards.
The wood burner also needs to be installed correctly. Check with your local council or a HETA member if you think your burner may not be correctly installed. A wood burner will perform better when located towards the centre of the home and not against an outside wall.
There are only two routes to legally install a domestic solid fuel, wood or biomass-
It is generally much simpler and cheaper to use a HETAS registered installer who will leave you with a Certificate of Compliance as a record of the job and that it complies with Building Regulations. A copy of the certificate is forwarded to HETAS who notify the local authority on your behalf.
Failure to notify the work through the registration scheme (in this case HETAS) or directly to the local authority can lead to enforcement. It can also cause problems for future house sales if there is no official record of a compliant installation.
Look after your wood burner, keep the burner well maintained and serviced. Make sure the chimney/flue is cleaned every year. Replace broken firebricks and keep the burner in good repair. Make sure the flue is insulated.
DIY repairs to wood burners are not recommended as this may also result in smoke or safety problems.
If the wood burner is difficult to start or smoke puffs out when the door is opened then the chimney is probably clogged with soot and needs to be swept. If your current burner is more than 10 years old it may need replacing so think about other cleaner forms of heating. Upgrade to an alternative that discharges low, or no, levels of pollutants.
