Wood-burning and eco stoves are commonly used to reduce heating costs in winter but release high levels of toxic pollutants. These substances pose serious health risks, including chronic respiratory issues, heart disease, and lung cancer. A study monitored homes in Guildford, revealing that open fireplaces have the highest emissions, with multifuel eco stoves producing even more ultrafine particles than standard models. Although modern stoves reduce overall emissions, significant pollution spikes occur during operation. Many cases showed pollutant levels exceeded WHO recommendations, emphasizing the importance of ventilation.
Wood-burning and eco stoves release high concentrations of toxic pollutants, posing serious health risks such as chronic respiratory conditions, heart disease, and lung cancer.
Researchers monitored five homes using various heating stoves, revealing that open fireplaces had the highest emissions, increasing PM2.5 exposure up to seven times the level of modern stoves.
Multifuel eco-design stoves emitted more ultrafine particle emissions than standard eco-design models, contrary to the belief that they are a cleaner option.
Pollutant levels from improved stoves often exceeded WHO recommendations, highlighting the need for better ventilation during lighting, refueling, and ash removal.
