Defra Exempt Multi Fuel Stoves

There is a great range of defra exempt multi-fuel stoves that can be used in any home. Defra approved appliances are compliant with the regulations of the government, and are designed to maximize efficient combustion and low emissions.

This is particularly important especially if you reside in a smoke control zone. Even if you do not need to, the Defra stove is safer for your chimney and the neighbours.

Defra Approved

You may have noticed that on our website, a variety of wood burning stoves are listed either as DEFRA exempted or DEFRA approved. To the average home owner, these terms may seem like jargon they do not need to be aware of, but this could not be further from the truth.

DEFRA is the Department for Environment, Food and Rural Affairs. They are responsible for the policies and regulations related to food, agriculture, and the environment. Defra approved stoves have passed a rigorous test to ensure they abide by the government's strict rules for emissions of smoke during operation. The stoves are specifically designed to burn the fuels of wood and coal more efficiently. This means they produce fewer pollutants.

This is good news for those who live in a Smoke Control Area because the law currently bans the release of smoke within such areas unless using an DEFRA approved stove and a fuel that is authorised. In the past it was possible to install an non Defra approved wood stove in a Smoke Control Area, as long as you used only authorised fuels. In January 2022, the laws will be altered and stoves that aren't approved won't be allowed to be used unless equipped with a secondary or tertiary system that can reduce the production of particulate matter, nitrogen oxides, carbon dioxide and organic gaseous substances.

In the case of our Defra approved stoves, they are equipped with a mechanism that will stop you from closing the top air vent all the way down, as this could cause the fire to smolder and release smoke into your space. Instead, these stoves come with an adjustable air supply that allows you to open the top vent a little and still maintain a safe and efficient burn.

Another benefit of buying a Defra approved stove is that it comes with a 5 inch chimney liner. This is important as many codes for building require chimneys to have a minimum 5-inch diameter.

Smoke Control Areas

If you reside in a zone of smoke control, you will need a Defra approved stove to legally burn wood in your home. These stoves have been inspected by DEFRA to ensure that they meet the strict standards for smoke emissions that are required in areas of smoke control. On the Defra site, you will find a list of places which require a stove that has been approved by DEFRA.

Multi Stoves Fuel

A Defra approved stove, also referred to as a DEFRA multi wood burning stove or fuel, will have passed a rigorous test designed by the Department for Environment, DEFRA approved energy-Efficient stoves Farming and Rural Affairs (DEFRA). The UK government agency responsible for ensuring the protection of our natural environment, assisting agriculture and food industry and ensuring a flourishing rural economic. The tests that Defra Approved Stoves must clear are designed to ensure that the stove produces small amounts of grit or smoke when it is operating.

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

The most recent Defra stoves for woodburning and multi-fuel are equipped with secondary and tertiary ventilation systems that ensure the wood is completely burned prior to leaving the chimney. This is more efficient than leaving a log on the fire for a long period of time. It also reduces the amount of nuisance smoke that can be produced.

If you reside in an Smoke Control Area, or if you are thinking of moving to one, a Defra exempt stove is an excellent choice for your home. It's not just more environmentally friendly however, it also helps to reduce the nuisance smoke that could make your neighbors angry.

You can still enjoy open fires, barbecues and pizza ovens in your backyard but be aware that toxic or excessive smoke could be a statutory nuisance and you could be fined. In an area designated as a Smoke Control Area You are not permitted to use open fires or stoves that burn damp, rotten or wet wood or other fuels.

Burning Other Fuels Besides Cars

Defra Approved stoves are designed to burn a wide variety of fuels including wood. They burn wood so cleanly that they are in compliance with the government's strict regulations for emissions in smoke control areas. You can use them in any smoke-control area, provided they are burning approved fuels, such as logs, briquettes and pellets. Stoves that have been certified by Defra will be marked with a SE' logo that stands for Smoke Exempt.

A Defra-approved stove is different from a conventional multifuel stove in that it has secondary air vents that pre-heat air prior to it entering the firebox. The pre-heated air helps ensure that the entire fuel is ignited and burned, resulting in an efficient combustion process. It also prevents the build-up of soot up and stops the chimney from becoming blocked. The Defra stoves come with internal baffles that help regulate the flames and ensure a uniform heat distribution.

Defra could impose severe penalties on anyone who uses a non-Defra approved appliance in areas with smoke control. To avoid being prosecuted by Defra you should only buy DEFRA stoves and use a DEFRA approved stove that has been tested to the government's strict standards.

DEFRA stoves are also known as Clean Burn stoves. They can be used with most types of fuel, however, they are most effective with wood that is dry and soft. The air vents can't be closed completely, so there's always oxygen to aid in clean combustion.

This technology is not only in line with the current air quality standards of the government, but also with future Ecodesign standards that will come in effect in 2022. Many of the Stovax wood burning and multi-fuel stoves we sell will bear this SIA Ecodesign Ready mark which confirms that they meet the new, stricter emission standards. These new standards are part of the government’s ongoing efforts to ensure that the air in the country healthy and clean.

Installation

If you are in a zone of smoke control then a Defra exempt multi fuel stove will assist you in complying with the regulations. These wood burning and multi fuel stoves have been tested independently in order to ensure they meet the strict smoke emission standards required in a Smoke control zone. These stoves can burn wood or other fuels, such as coal without worrying about the amount of smoke they generate.

Stoves that are Defra approved Energy-efficient stoves certified can reduce smoke levels by using advanced combustion technology that creates less smokiness. These stoves typically use an additional stage of combustion, which re-burns some of the waste products that were discarded from the first stage, making them cleaner and Defra Approved Energy-Efficient Stoves more efficient. In addition to reducing emissions they also reduce the amount of soot that builds up in the chimney and flue.

If you live in a region which is smoke-free this is an important idea to be aware of. You can enjoy a real fireplace more often and for a longer time. In addition, you'll save money on your utility bills. These multi-fuel and wood burning stoves are beneficial to the environment since they release less pollutant. They can also be used to burn more fuel than other stoves.

A simple kit provided by the manufacturer can make most stoves DEFRA-exempt. This alters the air vents of the stove to prevent them from closing at night. This is known as slumbering, and allows part-burned combustibles and flammables to escape into the atmosphere rather than going up the chimney, where they could block the flue. DEFRA approved stoves don't slumber, and are more sustainable for the environment. They also tend to block chimneys less often.

It is recommended that an HETAS registered installer or Building Control officer install your DEFRA approved appliance to get the most out of it. This will give you peace of mind that your installation has been done to the proper specifications and is in compliance with the latest regulations. It will also help protect your warranty, as the installer is able to self-certify their own work.
