Defra Exempt Multi Fuel Stoves

There is a variety of multi-fuel stoves that are exempt from the regulations of defra. Defra approved stoves are compliant with the regulations of the government and are designed to burn fuel efficiently and emit low emissions.

This is especially important especially if you reside in a smoke-free area. Even if you do not need to, it is important to know that a Defra Stove is more beneficial for your chimney and for your neighbors.

Defra Approved

You may have noticed across our website that many of our wood burning stoves are categorized as being DEFRA exempt or DEFRA approved. To the average homeowner these terms may sound like jargon that they do not need to be aware of, but this is not the reality.

DEFRA is the acronym for Department for Environment, Food and Rural Affairs and they handle regulations and policies regarding the environment, farming and food. Defra approved stoves have passed a rigorous test to ensure they adhere to the government's strict rules for the emission of smoke during their operation. The stoves are designed to burn fuels like wood and coal more efficiently. This means they emit less pollution.

This is a great news for those who live in a Smoke Control Area as the law currently prohibits emissions of smoke in these areas unless you use an DEFRA approved stove and an authorised fuel. In the past, it was possible to install a non Defra approved wood stove in a Smoke Control Area, as long that you used only authorized fuels. As of January 2022, the law will change and non-approved stoves won't be allowed to be used unless they are equipped with a secondary or third-party system that will reduce their productions of particulate carbon dioxide, nitrogen oxides and organic gaseous substances.

In the case of our Defra approved stoves, they're also equipped with a mechanism that stops you from closing the top air vent all the way down as this can cause the fire to smoulder and release smoke into your space. Instead, these stoves feature an adjustable air feed which allows you to open the top vent slightly and still maintain a safe and efficient burn.

Another advantage of purchasing a Defra approved stove is that it comes with a 5 inch chimney liner. This is crucial since there are a variety of building regulations which state that you need a chimney with at least a 5-inch diameter.

Smoke Control Areas

If you live in a smoke control area you'll require a Defra approved stove if you wish to legally burn wood in your home. These stoves have been inspected by DEFRA certified stoves to ensure that they meet the strict standards of smoke emissions required in smoke control zones. You can find the list of areas where you need a Defra approved stove on the Defra website.

Multifuel stoves and Defra exempt stoves

A Defra approved wood stove, also referred to as a DEFRA Multi Wood Burning Stove is one that has been through a rigorous test developed by the Department for Environment, Farming and Rural Affairs. The UK government agency is responsible for ensuring the protection of our natural environment, assisting the food and agriculture industries and maintaining a thriving rural economic. The tests Defra approved stoves must pass are designed so that the stove produces small amounts of grit or smoke when it is in operation.

Many of the Defra Exempt stoves we stock at Stove Supermarket are also multi fuel stoves which allow you to burn authorised smokeless fuels as well as seasoned wood. They are usually described as Defra stoves or Defra approved woodburners and they are often abbreviated to SE.

The most recent Defra multi-fuel stoves and woodburning stoves come with secondary and tertiary venting systems that ensure that the wood is fully burned before it leaves the chimney. This is more efficient than leaving a log on the stove for long periods of time. It also reduces the amount nuisance smoke that can be produced.

If you live or plan to move into a Smoke Control Area then a exempted stove from Defra is an excellent choice for you. Not only will it be more environmentally friendly but it can also help minimise the nuisance smoke that can irritate your neighbors.

You can still use open fires, barbecues and pizza ovens in your garden but be aware that smoke that is toxic or excessive could be a statutory nuisance and you may be fined. You are also not allowed to use damp, wet or rotting wood or any other fuels on an open fire or stove in a Smoke Control Area.

Burning Other Fuels

Defra Approved stoves are made to burn a wide range of fuels including wood. They burn wood so efficiently that they are in compliance with strict government regulations for emissions when operating in smoke control zones. They can be used in any smoke control area so long as they're burning approved fuels, such as pellets, briquettes, and logs. Stoves that are Defra Approved are usually identified with the a 'SE' logo which is a reference to Smoke Exempt.

A stove that is Defra-approved differs from a typical multifuel stove in that it has secondary air vents that heat air before it enters into the firebox. This pre-heated air helps to ensure that the entire fuel is ignited and burned, which results in a cleaner combustion process. This also prevents the build-up of soot and blockages in the chimney. Defra stoves also have internal baffle plates that help to control the flames and maintain an even heat distribution.

Using non-Defra approved stoves in areas with smoke control could result in heavy fines from the UK government's Department for Environment, Food and Rural Affairs (Defra). If you wish to avoid being accused of being prosecuted by Defra, only use a DEFRA-approved stove that has been tested in accordance with the government's guidelines.

DEFRA stoves are also known as Clean Burn stoves. They are compatible with all types of fuel but are ideally suited for dry wood, both soft and hard. They're built with air vents that cannot be closed completely, so the stove will always receive a supply of oxygen to ensure clean combustion and minimise soot and noxious gases.

This technology not only complies with the current standards for air quality, but also with the future Ecodesign requirements that will come into effect in 2022. Many of the Stovax wood-burning and multi-fuel stoves we sell will have this SIA Ecodesign Ready mark which signifies that they are in compliance with the new, stricter emission standards. These new standards are being introduced as part of the government's continued efforts to keep the nation's air clean and healthy.

Installation

If you reside in a Smoke Control Area and you are in a Smoke Control Area, a Defra exempt multi stove can help you comply with the rules. These wood burning and multi fuel stoves have been tested independently to ensure that they comply with the strict standards of smoke emission that are required in a smoke control zone. They can burn wood or other fuels like coal without worrying about the amount of smoke they generate.

Stoves that have been DEFRA approved stylish stoves approved can lower the amount of smoke produced by advanced combustion technologies that create less smokiness. They usually employ a second phase of combustion that re-burns some of the waste materials from the initial stage, making them even more efficient and cleaner. In addition to the reduction in emissions they also reduce the amount of soot that builds up in the chimney and flue.

This is great news especially if you reside in a smoke-free zone as it means you can sit in front of a real fire more often and longer, with the added benefit of lower utility bills. Due to the lower levels of pollution, these types of wood-burning and multi fuel stoves are beneficial to the environment since they are able to burn a wider variety of materials than other stoves.

Most stoves can be made DEFRA exempt by using the simple kit supplied by the manufacturer. This alters the air vents of the stove to prevent them from closing at night. This is referred to as slumbering, and allows part-burned combustibles and flammables to escape into the atmosphere rather than being pushed up the chimney where they can block the flue. DEFRA approved stoves do not sleep, and therefore are more eco-friendly and far less likely to block a chimney.

It is recommended that a HETAS registered installer or Building Control officer install your DEFRA approved appliance to get the best out of it. This will provide you with the assurance that the installation was done to the proper specifications and is in compliance with the most current regulations. In addition, it can also ensure your warranty since the installer will be able to self-certify their work.
