What is a Defra Approved Wood Burning Stove?

If you live in a smoke control area then it is crucial to purchase a DEFRA exempt stove. A DEFRA exempt stove (or SE) permits you to legally burn wood in a smoke-controlled area.

The stoves are independently tested for the lowest emissions possible. Stoves that are certified as such often feature the logo 'Defra-approved' in their name or specification.

Approved for Smoke Controlled Areas

Many people believe that living in a smoke control area means they can't make use of a fireplace that burns wood. This isn't the case. The majority of towns and cities fall under a smoke control zone however, that doesn't mean that they aren't able to use a wood burning stove. It's simply that they have to burn approved fuels in their stove (usually brquettes). The Defra-approved stove is a wood-burning stove that has been rigorously tested to ensure that it is in compliance with certain requirements in terms of the emissions it generates when burning authorised materials. It is therefore able to be legally used in areas of smoke control.

The Defra logo is widely adopted in the industry and many of the stoves that have been approved have SE after their names, meaning they are smoke exempt. In order for a stove to be SE approved, it must satisfy strict requirements in relation to its emissions, so you can be assured that when you purchase a stove that is defra exempt, you will receive the cleanest and most efficient wood stove available.

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

A stove that is Defra-approved allows you to use a 5" liner which is compliant with UK building regulations. Non-Defra-approved stoves require a 6" liner.

At Stovax we are pleased to offer a variety of Defra approved stoves and fires, as well as our Ecodesign Ready stoves that have been developed with the future standards of air quality in mind. Many of our stoves that are DEFRA permitted stoves-approved can also be used in combination with a smoke control system for properties located in Smoke Control Areas. They can be used to burn a variety of in smokeless fuels, including fire logs.

Approved for Smokeless Fuels

The only stove that can be used within a smoke-control zone is one that is a DEFRA approved wood burner, which is also known by the designation DEFRA exempt. This stove should be used for solid fuel, which means wood, and preferably well-seasoned. The government tests them to ensure they don't emit excessive smoke and that they can be used only with 'authorized' fuels.

The difference between a DEFRA permitted stoves-approved stove and one that isn't approved is usually very small. With a kit provided by the manufacturer, many modern stoves can be easily made DEFRA conforming in just a few 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 the restrictions are kept the stove has to be able to limit its combustion air to ensure that it doesn't deprive itself of oxygen which can cause it to smolder. This is accomplished by a mechanism that opens a small amount air into the firebox when it's burning. It is usually hidden in the stove or under the base of the firebox.

Stove World UK offers a vast selection of DEFRA stoves benefits approved stoves from the best brands in the country, including Stovax, Arada and Burley. These are available in a wide variety of styles and colors.

Smoke Control Areas are typically situated around large towns and city centres and you can check the website of your local authority to determine if the area you live in is classified as one. If you reside in a zone that is smoke-free, it is essential that you purchase a luxury DEFRA Stoves; http://trendi.kr, approved stove for your home to avoid being fined by your local authority. If you use coal or any other solid fuels in a stove that is not approved stove, you could be fined PS300.

Approved for Wood

A DEFRA approved wood stove, also called a smoke-free stove is an appliance that can be used in a Smoke Control Area when burning wood. The stove will bear the Defra approved symbol or 'SE' the front of its name meaning it is only permitted to be used in smoke-controlled areas if you burn approved fuels. In this instance wood is the fuel.

A lot of older wood stoves release a lot of particulate matter into the air, which can cause or contribute to respiratory issues asthma attacks, heart issues and premature death. It is therefore essential to purchase a stove that is in compliance with strict emission standards as set by the Environmental Protection Agency. Look for an "EPA 2020 Certified" label, which indicates that the stove has met the emission limits that are currently in place.

If you purchase a stove that isn't EPA certified and you live in a smoke control area you must be able to get it certified before you can use it. It is expensive and time-consuming, however the law requires it. Additionally homeowners who sell a home that has a wood stove that is not certified could be liable for clean air tax credits and fines.

With a kit or an adjustment made by the installer, the majority of modern stoves can be Defra approved. The primary difference between DEFRA approved stoves and those 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. The modifications are usually made on the underside of the firebox or in the base.

Some manufacturers produce two versions of a wood stove: one that is Defra-approved and the other not. The reason is that the cost of putting a stove through the rigorous DEFRA approved British stoves testing is costly. To offset the costs, they sell the non-approved version at a lower cost. The DEFRA approved version will have had the combustion air modification done as part of the testing procedure.

Approved for Gas

Before the Clean Air Acts were brought in residential homes could burn any type of fuel they wanted, which resulted in huge quantities of smoke emissions and health problems. To prevent this, top DEFRA stoves established Smoke Control Areas. This meant that homes could not emit smoke in the event that their wood burners or multifuel stoves were Defra-approved to allow burning only approved materials such as manufactured smokeless coke and anthracite.

Defra approved SE (Smoke-Exempt) Stoves have been put through rigorous tests 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 constantly delivers a minimum level of secondary air to the firebox so that even if the stove is being used with fuels that are authorised, such as anthracite or manufactured smokeless coals it will still be able to meet Defra's regulations for Smoke Control Areas.

If you're looking for an all-new wood burning stove and live in Smoke Control Area then we would recommend to look into the wide selection of Defra approved stoves which can be found at The Stove Yard. We offer a wide collection of traditional, contemporary and inset Defra approved stoves from the most reputable manufacturers such as Stovax, Arada, Burley and AGA.

The good thing is that there is no visual difference between a stove that is Defra-approved and a non-approved model. However the models that are Defra-approved include a few features designed to help them burn cleaner. They generally have a different grate design and air vents, and on the gas models they might also have a different sized flue outlet.

A Defra Approved Stove will almost always have 5" flue outlet (125mm). This means you can choose a smaller stainless twin wall flexible liner that is less expensive than a 6" (150mm). We've found this useful when the customer has an old or non-standard chimney stack which we are installing a Defra approved wood burning stove into and it saves the cost of re-lining the chimney stack with a bigger diameter liner.
