What is a Defra Approved Wood Burning Stove?

If you reside in a zone of smoke control then you must purchase a DEFRA exempt stove. A DEFRA exempt stove (or SE) allows you to legally burn wood in a smoke controlled area.

They are independently tested to provide the lowest possible emissions. Stoves with this status typically carry the 'Defra approved' logo in their name or on their specifications.

Approved for Smoke Controlled Areas

Many people believe that living in a smoke-free area means they can't use a wood burning fireplace. This isn't the case. In reality, many cities and towns are within a smoke-free zone, but this doesn't mean you cannot use a stove, it just means you need to make use of an exempt device and only burn authorised fuels (usually Briquettes) in your stove. The Premium DEFRA Stoves approved stove is a kind of wood burning stove that has been inspected to ensure it meets certain criteria in regards to the emissions it emits when burning authorised fuels and therefore, it can be legally used in a Smoke Control Area.

The Defra logo is widely adopted by the industry and a large number of the stoves that have been approved have SE after their names which means they are smoke free. To be SE approved the stove must meet strict emission requirements. This means that you can be sure that you are buying the best wood stove that is available.

If you search for a wood-burning stove that is Defra exempt or has SE after its name, you'll usually find that the manufacturer has carried out things like making sure there enough air inlets on the front of the stove to allow full combustion of the fuel, and that the chimney outlet is large enough to prevent soot build-up. This is important as it ensures that the smoke from the wood stove is not able to escape through the chimney and into your home.

Another benefit of a Defra approved stove is that it usually allows you to fit it with five" chimney liner, which will comply with the UK building regulations, whilst non-Defra approved stoves will need to be fitted with a bigger 6" liner.

The government tests them to ensure they don't produce excessive smoke and can be used only with fuels that are 'authorized.

The difference between a DEFRA-approved stove and one that is not approved is usually very small. With a kit provided by the manufacturer, many contemporary stoves can be easily converted to DEFRA stoves comparison compliant in minutes. This is because Defra approved appliances must pass extremely rigorous tests and are limited in the amount of smoke they are able to produce.

To ensure that these limitations are not violated during testing, the stove needs to be capable of limiting the amount of combustion air it gets to ensure that it doesn't starve itself of oxygen, which could cause it to smolder. This is accomplished by the mechanism that allows a small amount air into the firebox when it's burning. It is typically hidden in the stove or under the base of its fire box.

The older wood stoves can release lots of particles into the air which can trigger or contribute to respiratory problems asthma attacks, heart problems and premature death. This is why it is crucial to purchase new wood stoves that meets the strict emission standards established by the Environmental Protection Agency (EPA). Look for an "EPA 2020 Certified" label, which indicates that the stove is in compliance with the emissions limits currently in place.

If you purchase an appliance that isn't EPA certified and you reside in a zone of smoke control it is necessary to get it recertified before you can use it. It can be costly and time-consuming, but the law requires it. Homeowners who sell a house with a wood stove that is not certified may also be subject to tax credits or fines relating to pollution-free air.

The majority of modern stoves can be altered to become Defra approved using a kit or an adjustment that the installer offers. The major difference between DEFRA approved stoves and ones that aren't is the combustion air control system that controls the quantity of air that goes through the stove when it is operating normally. Modifications are typically applied to the base or the underside of the firebox.

Certain manufacturers will make two versions of their wood stove one that is Defra approved and the other that is not. This is due to the process of putting a stove through the stringent Defra tests is expensive, so to help recoup some of the costs, they'll offer the non-approved model at a lower price. The DEFRA-approved version will have been through the modification to the combustion air as part of the testing procedure.

Approved for Gas

Before the Clean Air Acts were brought into effect, residential homes could use any kind of fuel they wanted which resulted in huge amounts of smoke emissions as well as health problems. To combat this, Defra established Smoke Control Areas. This meant that homes could not emit smoke in the event that their wood burners or multifuel stoves were DEFRA compliant stoves UK-approved for burning only approved substances like manufactured smokeless coke and anthracite.

Defra approved stoves, also known as SE (Smoke Exempt) Stoves, have been subjected to rigorous tests to prove that they are able to burn cleanly authorised fuels within a Smoke Control Zone. They accomplish this by using the latest combustion technology which continuously delivers a minimum amount of secondary air to the combustion chamber, so that even if the stove is used with approved fuels like anthracite or manufactured smokeless coals, it will still be able to comply with the regulations of Defra for Smoke Control Areas.

The Stove Yard has a large selection of Defra-approved stoves that are ideal for those who live in a smoke control zone and require a brand new wood-burning fireplace.

The good thing is that there's not any noticeable distinction in appearance between a Defra approved wood-burning stove and one that isn't, but the Defra approved models have several features that are designed to ensure that they burn cleaner. They typically have an aesthetically different grate and air vents and on gas models, they may have a slightly different size flue outlet.

Another benefit of the Defra Approved stove is that they'll almost always come with a 5" (125mm) flue outlet, which means you can choose a narrower stainless steel twin wall flexible chimney liner which is less expensive than the standard 6" (150mm) liner. We've seen this helpful when customers have an old or non-standard chimney stack that we are installing a Defra approved wood-burning stove in and it saves the cost of relining the chimney with a wider diameter liner.
