5 Defra Approved Multi Fuel Stoves List Lessons From Professionals
Wood Burning and Multi Fuel Stoves That Are DEFRA Approved

Multi fuel and wood burning stoves that are DEFRA approved, also referred to as Defra Smoke Exempt, have passed stringent emissions tests. This means they can be used in UK cities and large towns that are classed as smoke control zones.

Defra Approved

If you reside in an UK Smoke Control Area and would like to use wood for your stove, you will require a DEFRA approved appliance or Defra-exempt appliance. This is because DEFRA stands for Department of Environment, Food and Rural Affairs and the government prohibits the release of noxious smoke into cities and towns where it could create an issue for residents. These appliances have undergone stringent tests to ensure that particulate emissions are drastically decreased, and are capable of passing the rigorous Defra smoke tests.

The Defra logo or DEFRA exemption logo is widely known and widely used by industry. You'll often find it engraved or printed on the stove, however sometimes the wording is written in the specification sheet. You will also come across several models that are DEFRA approved and DEFRA exempt, which means that they can be used for both wood and solid fuels.

A wood-burning stove which has been endorsed by Defra has undergone extensive tests to determine how much particulate matter it creates. It is able to conform to the Clean Air Act by supplying the minimum amount of combustion air to the fuel, so that it burns efficiently without releasing excessive smoke. These stoves are more environmentally friendly than non Defra approved stoves and will also help you save money by reducing the cost of heating.

Defra approved wood-burning stoves can be especially useful for those who reside in Smoke Control Area. You might be penalized a lot in the event that you use a non Defra approved wood burning stove in a Smoke Control Area. A stove that is approved by Defra is more considerate of neighbors since it doesn't emit any noxious fumes. It also keeps your chimney and flue clean for longer.

A DEFRA approved wood burning stove can also allow you to legally install a stove of 5kW with stainless steel twin wall flexible liner (provided the manufacturer doesn't require a larger diameter). It is worth considering this option if you're trying to save money by not having to buy an entirely new chimney.

Exempt from Defra

If you live in an area where smoking is not permitted an approved DEFRA stove is a must-have. The stoves have been thoroughly tested to ensure they produce low levels of emissions, which reduces the amount of particulate matter within your home (PM10).

DEFRA approved stoves are identified with a Defra Approved or a DEFRA Exempt logo. Stoves with the logo have been independently tested and meet the strict requirements for smoke control.

It is crucial to note that you are not able to use Defra Exempt stoves to burn dry wood in a Smoke Control Zone as this will produce nuisance smoke. Also, you should not use non-Defra Approved multi fuel stoves unless they are located in a Smoke Control Area because this could create PM10 in your house and could result in a hefty fine from your local council.

Defra approved multi fuel stoves are engineered to burn wood that is authorised and smokeless coal safely, without producing noxious smoke. This is achieved by using the latest technology for combustion that doesn't hinder the flow of air into the fireplace, which is also known as sleeping. Stoves that are left to sleep overnight can produce excessive black smoke, which is bad for your chimney and stove.

A great example of a top-quality Defra Exempt multi fuel stove is the Stovax Vogue small. The popular wood burning stove is extremely efficient with a maximum heating output of 5kW. It also has an inbuilt log store base which makes it perfect for installation into larger fireplace openings.

ACR Earlswood LS is a different multi-fuel wood burner that has been endorsed by DEFRA. The Earlswood multi-fuel stove also has been subjected to extensive testing to ensure it meets the strict DEFRA requirements for particulate emissions. It is therefore suitable for use in smoke-controlled areas and is able to burn a variety of wood and approved smokeless fuels.

A multi-fuel stove that's DEFRA Exempt can be an inexpensive option to replace your chimney lining. Since they almost all have a 5" flue outlet this means that you can fit an 125mm diameter stainless steel twin wall flexible chimney liner rather than the standard 6" (150mm). This is particularly economical when there isn't enough space to install a larger liner, and particularly beneficial if the existing chimney stack has difficult bends that make it difficult to install a traditional 6" chimney liner.

Smoke Control Areas

Many regions in the UK have been designated as Smoke Control Areas. This means that if your house has an open fire or wood-burning stove, or fireplace, you can only use fuels that have been approved by the UK government. This law is designed to reduce the amount of smoke that is emitted into the neighbouring properties and to ensure that the environment is maintained clean. It does not prohibit the use of solid fuel appliances or stoves that meet certain requirements. DEFRA approved stoves, also known as Defra exempt stoves, are an excellent option if you reside in a smoke-free zone because they've been specifically tested to meet the requirements.

A Defra approved stove can burn all approved fuels, including wood without generating excessive smoke. To accomplish this, the combustion technology used in a Defra approved stove has been developed to limit how starved the stove is of air during the burning process. Usually, this is accomplished by using specially designed baffles in the stove which redirect airflow and stop it from leaving the stove.

The most effective DEFRA approved stoves will include"clean burn" feature which allows the combustion of combustibles with a part-burn such as soot and ash and lets them be released from the chimney instead of into the room. This feature blocks combustibles which are partially burned from entering the stove again and causing a buildup that would eventually cause black smoke.

If you have a stove with Defra exemption, it is important to burn only the specified types of fuels in it, as failing to do so could result in fines under the Clean Air Act. This is especially the case when you are burning damp wood or other wet fuels which can produce fumes that are noxious. Check with your stove's manual or with your supplier to determine which fuels are permitted in your stove.

Gr8Fires offers a range of DEFRA-exempt stoves suitable for smoke-controlled areas. The Dimplex Langbrook, for example is a fashionable wood-burning fireplace that is Defra exempt and can be used with a broad range of authorised fuels. This model comes with a range of heat outputs, as well as in a range finishes including a matt black finish.

Heat Output

If you see the Defra approved symbol on the stove, that means it is suitable for use within a smoke control zone when burning wood or other permitted fuels. The Defra certification process requires rigorous testing and examination to ensure that the stove is in compliance with the Department of Environment requirements for low emissions. These features help the stove be more efficient in heating your home, which can help to lower your heating bills and reduce your carbon footprint.

There is a variety of Defra approved multi fuel stoves that are available, from small 4kW models to large 5kW models. The right model depends on many factors, such as the size of the room and the amount of heat required. A stove that is too large for your room can cause excessive heating and result in burning out of fuel. When choosing no title -fuel or wood-burning stove, it's important to seek professional advice.


In addition to Defra approval, you should also look for a stove that is compliant with Ecodesign 2022 regulations. These regulations aim at improving the energy efficiency of appliances and minimize environmental impact. Ecodesign 2022 stoves are made to burn fuel more efficiently, which results in less CO2 emissions as well as other harmful pollutants. These stoves are also simpler to clean since they produce less soot and tar than other stoves.

The majority of multi fuel stoves that are Defra-approved have air controls that can be adjusted to control the amount of fuel that is burned. They also have a an ash pan, grate and ash collector to ensure efficient combustion of smokeless coal. The ash pan collects the ashes from the firebox, and keeps them from affecting the air flow to the combustion chamber.

Multi-fuel stoves are available in a variety of different styles and colours. Colors such as navy and red create a dramatic look to your space. Metallic finishes can provide an elegant, modern style. Multi-fuel stoves come in a variety of sizes, so you can choose the one that best suits your space.
