What is a Defra Approved Wood Burning Stove?

If you reside in an area where smoking is controlled, it's crucial to buy a DEFRA exempt stove. A DEFRA stoves installation exempt stove (or SE) permits you to legally burn wood in a smoke-controlled area.

The stoves are tested independently to ensure the lowest emission possible. Stoves with this certification often feature the logo 'Defra-approved' in their names or specifications.

Approved for Smoke Controlled Areas

Many people believe that living in a Smoke Control Area means you can't have a wood burning stove but this isn't the case. Many towns and cities fall under the smoke control zone, however that doesn't mean you can't use a wooden burning stove. It just means they have to burn approved fuels in their stove (usually Briquettes). The stove that is Defra-approved is a wood-burning stove that has been thoroughly tested to make sure that it is in compliance with certain requirements regarding the emissions it produces when burning authorised materials. It can therefore be used legally in a smoke control area.

The DEFRA approved energy-efficient stoves Logo is widely used in the industry, and many stoves have the SE after their names to indicate that they are smoke-free. To be SE approved the stove must meet strict emission requirements. This means you can rest assured that you are buying the best wood stove that is available.

If you are searching for a wood-burning stove which is Defra-exempt or has SE after its title, you will find that the manufacturer might have taken measures to ensure that there are sufficient air intakes on the front of the stove to allow for full combustion of fuel, and that the size of the chimney outlet is adequate to prevent the accumulation of soot. This is important because it ensures that smoke from the wood burning stove does not escape through the chimney and into your home.

A stove that is Defra-approved permits you to use a 5" liner that is in compliance with UK building regulations. Non-Defra-approved stoves require an 6" liner.

Stovax is proud to offer a range of fireplaces and stoves that are Defra-approved and Ecodesign Ready stoves which have been designed keeping future standards for air quality in mind. In fact, many of our Defra approved stoves are also suitable for use with a smoke control kit for those properties that are in a Smoke Control Area and therefore can be used with a variety of approved smokeless fuels, including fire logs.

Approved for Smokeless fuels

The only stove that can be used inside a smoke-control zone is a DEFRA approved wood burner, which is also known as DEFRA exempt. The stove has to be used with solid fuel, which is wood, which is best seasoned. They are tested by the government to ensure that they don't generate excessive levels of smoke and are able to be used with 'authorized fuels (coal only).

The difference between the differences between a DEFRA approved stove and one that is not is usually very little. Many modern stoves can easily be converted to DEFRA certified by the kit supplied by the manufacturer and then fitted in just a few minutes. This is because the Defra approved stove has to undergo very rigorous tests and must be restricted to the amount of smoke it can generate.

To ensure that these limitations remain in place during the testing process, the stove must be capable of limiting the combustion air supply to ensure that it doesn't exhaust itself of oxygen, which may cause it to smoulder. This is accomplished by a mechanism that opens an air pocket in the firebox when it is burning. It is typically hidden within the stove or beneath the base of the firebox.

Stove World UK has a large selection of DEFRA approved stoves, from some of the best manufacturers in the country such as Stovax Arada and Burley. These are available in a vast range of styles and finishes. You can also choose from an impressive selection of Ecodesign ready stoves that have been designed to meet the future standards for air quality.

Smoke Control Areas are typically located around large towns and city centres and you can look up the website of your local authority to determine if your area is classed as such. It is essential to buy an approved DEFRA-approved stove if reside in a smoke-controlled zone. This will help you avoid being fined by the local authority. If you burn coal or any other solid fuels in a non approved stove, you could be fined up PS300.

Approved for Wood

A DEFRA approved stove, also known as a smoke-free wood stove is an appliance which can be used to burn wood in the Smoke Control Area. The stove will have the Defra approved symbol or the word 'SE' in front of its name meaning it can only be used in smoke-controlled areas where you can burn approved fuels. In this instance wood is the fuel.

Many older wood stoves emit lots of particulate matter into the air, which can cause or contribute to respiratory problems, asthma attacks, heart issues and premature death. This is why it's crucial to purchase a new wood stove that meets the strict emission standards set by the Environmental Protection Agency (EPA). Look for an "EPA 2020 Certified" label, which means that the stove meets the emissions limits currently in place.

If you purchase an appliance that isn't EPA certified and you reside in a smoke-free zone you must get it recertified before you can use it. It is costly and time-consuming, but the law requires it. Homeowners who decide to sell a property with wood stove that is not certified could be liable for tax credits or fines that relate to pollution-free air.

With a kit or an adjustment provided by the installer, the majority of modern stoves can be made Defra-approved. This is because the primary difference between the DEFRA approved stove and those which aren't, is the combustion air management system that regulates the amount of air that passes through the stove during normal operation. The change is usually made on the underside of the firebox, or in the base.

Some manufacturers produce two different versions of a wood stove: one that is Defra-approved, and the other is not. The reason is that the cost of putting a stove through the rigorous Defra testing is costly. To help recoup these costs, they will sell the non-approved version at a lower price. The DEFRA-approved version will have been subjected to the modification of the combustion air in the course of the test procedure.

Approved for Gas

Before the Clean Air Acts were brought into effect, residential homes could use any type of fuel they wanted, which led to large amounts of smoke emissions as well as health issues. To stop this, Defra established Smoke Control Areas. This meant that residential homes could not produce any smoke except if their wood burners and multifuel stoves were DEFRA stoves price range-approved to allow burning only approved substances like manufactured smokeless coke and anthracite.

Defra approved SE (Smoke-Exempt) Stoves have been subjected to rigorous testing to prove that they can safely burn approved fuels in a Smoke Control Zone. They achieve this by utilising the latest technology for combustion that continually delivers a minimum amount of secondary air to the firebox so that even if the stove is being used with authorised fuels such as anthracite or manufactured smokeless coals, it can still meet Defra's regulations for Smoke Control Areas.

If you're in the market for an all-new wood burning stove and you live in an area that has a Smoke Control Area then we would recommend to look into the selection of Defra approved stoves which can be found here at The Stove Yard. We have an extensive selection of contemporary, traditional and inset Defra approved stoves from the most reputable manufacturers like Stovax, Arada, Burley and AGA.

The good thing is that there's not much of a distinction in appearance between an Defra approved woodburning stove and one that isn't. However, the DEFRA stoves ratings approved models have several features that are designed to ensure they burn more efficiently. In general, they have a different design of grate and air vents and on gas stoves they may also feature an alternative size flue outlet.

Another benefit of a Defra Approved stove is that they will almost always come with five" (125mm) flue outlet. This means that you can choose a narrower stainless steel twin wall chimney liner that is cheaper than the standard 6" (150mm) liner. We've used this when customers have an old or non-standard chimney stack that we are installing a Defra approved wood-burning stove in and it reduces the cost of re-lining the chimney stack with a larger diameter liner.
