5 Defra Log Burner Lessons From The Pros

What is a Defra Log Burner?

The Department for Environment, Food & Rural Affairs regulates the release of smoke from wood-burning stoves. There are regulations that ban chimney smoke in Smoke Control Areas in the event that you use an exempt device or authorised fuel.

The new rules limit the amount of smoke that a stove can emit to 3g/hour and homeowners will be subject to severe on-the-spot fines in the event of non-compliance. To keep this from happening, only use a log burner that has been approved by Defra and burn kiln-dried wood marked with the 'Ready to Burn" label.

What is a Defra Approved Stove?

A stove that is Defra-approved that has passed the DEFRA test. It is therefore exempted from smoke control laws in areas where wood (and other materials that are authorised) are allowed to be burned. The Defra logo is well-known and has been adopted by the industry. Stoves that have been endorsed by Defra will often be marked with SE (Smoke-Exempt) as a quick and easy way to identify them.

Stoves that are Defra Approved are tested by the Department of Environment, Food & Rural Affairs (DEFRA) to ensure that they meet strict emission standards. These tests are designed to test stoves that generate maximum heat with ultra-low levels of smoke emissions. These emissions are typically attained by ensuring that combustion gases are reburned in the secondary burning. This is important because it allows the burning to continue at a high efficiency while reducing the amount of part-burned combustibles that are emitted into the atmosphere.

DEFRA exempt stoves are also more eco-friendly than other wood burning stoves since they are less likely to release part-burnt combustibles being transported down the chimney. In contrast to stoves that require to shut the air vents to allow them to  sleep overnight, Defra exempt stoves always keep their flue open, meaning they are much less likely to discharge part-burnt combustibles to the chimney where they can hinder its flow.
