Are Wood Burners Bad for Your Health? Debunking the Myths

In recent times, there has been a surge in concerns about the potential health risks associated with wood burners. However, a comprehensive literature review conducted by Dr Amanda Lea-Langton, a senior lecturer in Bioenergy Engineering at the University of Manchester, challenges these perceptions. Let’s delve into the key findings and debunk the myths surrounding the alleged dangers of wood burners.

The Literature Review: Dispelling Misconceptions

The literature review examined studies on indoor air quality associated with wood-burning stoves in the developed world. Contrary to popular belief, no scientific evidence was found to support adverse health effects linked to exposure from modern, enclosed wood-burning stoves.

Key Findings:

  1. No Adverse Health Impacts: Dr Lea-Langton’s review revealed no scientific evidence supporting adverse health impacts from exposure to indoor air associated with modern wood-burning stoves. This challenges the common misconception that these stoves are detrimental to our health.
  2. No Association with Asthma Risk: The review found no association between exposure to indoor wood burning and the risk of asthma in developed countries. This dispels fears that wood burners contribute to respiratory issues.
  3. Air Quality Improvement: Modern wood-burning stoves, when used properly, can actually help improve indoor air quality. The natural draught created during operation pulls air from the room into the appliance and from outside, contributing to a healthier indoor environment.
  4. Comparison with Other Sources: The review emphasized that other sources of particulate matter in the home, such as cooking, can release higher levels of PM compared to modern wood-burning stoves. Cooking practices, including frying and grilling, were identified as potential greater health risks.

Additional Studies Support the Findings

Supporting the literature review, a 2021 study conducted by Manchester University found that candles, incense, and hairspray produced higher PM10 and PM2.5 readings than the use of a modern Ecodesign stove. Notably, cooking a fried breakfast resulted in PM readings over 20 times higher than the WHO recommended limit.

Mitigating Concerns: Best Practices for Wood Burner Users

While some studies observed peaks in indoor PM exposure during wood burner refuelling and ash removal, these concerns can be mitigated through better awareness among users. Following the manufacturer’s instructions during refuelling and ash removal is crucial to minimize any potential risks.

Response from the Stove Industry Alliance (SIA)

James Verlaque, technical manager of the SIA, emphasized the importance of understanding the impact of indoor air quality on health. He stated that the findings of the review do not support the assertion that wood-burning stoves are detrimental to health. Verlaque highlighted the need for further research and pointed out that modern stoves should not be compared with less sophisticated solid fuel combustion practices in the developing world.

Addressing Myths: SIA’s 2020 Video

The SIA video provides valuable insights into the misconceptions surrounding wood burners and presents facts to counter these myths. By watching the video, viewers can gain a better understanding of the environmental impact of wood-burning stoves and how these appliances compare to other sources of particulate matter. This visual resource serves as a powerful tool to complement the information presented in this blog, reinforcing the evidence that supports the safety and benefits of modern wood-burning stoves.

Choosing Eco-Friendly Options: DEFRA Approved Stoves

For those concerned about environmental impact, DEFRA-approved, eco-compliant stoves provide a reassuring choice. These stoves adhere to low-emission legislation, ensuring that you can enjoy the warmth of a wood-burning stove while caring for the environment.

Conclusion: The Verdict on Wood Burners and Health

In conclusion, the literature review and additional studies provide compelling evidence that challenges the notion of wood burners being harmful to health. Modern, enclosed wood-burning stoves, when used correctly, do not pose significant risks to indoor air quality. It’s crucial to dispel myths and promote accurate information to enable informed decisions about the use of wood burners in our homes.
