A standard, non-eco-friendly wood burner typically produces 8,000 to 15,000 British Thermal Units (BTUs) of heat per hour. Eco-friendly burners produce considerably fewer BTUs, usually between 4,000 and 6, 500. On average, it takes about 1 ton of wood to generate around 24 million BTUs of heat. When a wood burner is burning efficiently, however, each ton of wood can yield up to 28 million BTUs of energy. Therefore, being mindful of your fuel consumption and burning efficiency is the key to getting the most out of a wood burner. The ideal temperature of the burner should be between 260 and 460°C.
