Wood heating has long been a staple of Australian homes, offering comfort, warmth, and a connection to tradition. But as our understanding of air quality and health impacts evolves, so too must our approach to home heating.
Recent media coverage such as the ABC’s article on wood smoke and health has reignited public interest in how wood heaters contribute to air pollution. Not everyone agrees with the ABC’s stance, as seen in commentary from outlets like Sky News, but what’s clear is that the conversation is shifting.
At the Australian Home Heating Association (AHHA), we believe it’s time to shift the conversation from criticism to solutions. The reality is simple: not all wood heaters are created equal, and the difference between a modern, certified unit and one that’s 10+ years old is significant – both for your health and the environment.
Key Differences Between Modern and Older Wood Heaters
Modern wood heaters are designed with advanced combustion technology that drastically reduces emissions. Here’s how they compare:
| Feature | Older Wood Heaters | Modern Wood Heaters |
| Emission Levels (when tested to AS/NZS 4013) | Often exceed 4 g/kg | Less than 1.5 g/kg (majority of compliant models are below 1.0 g/kg) |
| Efficiency | Lower heat output per kg of wood | Higher efficiency, less wood needed |
| Air Quality Impact | Higher particulate emissions | Cleaner burn, reduced smoke |
| Design Standards | Pre-2014 models may not meet current standards | Built to meet or exceed current regulations |
| Health Risk | Greater contribution to indoor/outdoor pollution | Lower risk due to cleaner combustion |
Why Upgrading Matters
A Smarter, Cleaner Future
We’re not here to deny the science – we’re here to act on it. The AHHA continues to advocate for responsible wood heating and supports initiatives that encourage households to upgrade outdated appliances.
If you’re still using a wood heater installed over a decade ago, it might be time to consider an upgrade. Not only will you enjoy better performance and efficiency, but you’ll also be contributing to cleaner air for your community.
What About Traditional Fireplaces?
While traditional brick fireplaces carry a sense of heritage and charm, they were never built with clean combustion or efficiency in mind. These older designs often release more smoke and generate less heat, making them a less sustainable choice for modern homes. If you’re still burning wood in a traditional brick fireplace, it may be worth considering a modern, low-emission insert-style heater. These units are designed to burn cleaner, produce significantly more heat, and align with today’s environmental standards, offering a practical upgrade without sacrificing the warmth and ambiance you love.
Burning Wood Responsibly
Getting the best performance from your wood heater starts with how you use it. A clean flue free of creosote build-up ensures optimal airflow and safety. Always choose dry, seasoned firewood from a trusted local supplier, and make sure your fire burns brightly. If it’s smouldering, open the air control and stir the logs to help it breathe. After adding new wood, leave the air control open for at least 20 minutes to allow the fire to establish before reducing airflow. It’s also a good habit to step outside and check your flue, if you see visible smoke, reopen the air control until the fire is burning cleanly. And above all, be mindful of your neighbours, especially those who don’t use wood heating.
A Cleaner Future Starts at Home
Whether you’re replacing an older unit or rethinking how you use your current one, small changes can lead to big improvements in air quality and comfort. At AHHA, we’re committed to supporting responsible wood heating and helping Australians make informed, sustainable choices for their homes.
