These stoves are designed to burn fuels like wood and coal more efficiently. This means they generate less pollutants.

This is good news for those who live in a Smoke Control Area since the law currently bans the release of smoke in these areas unless using a DEFRA approved stove and a fuel approved by DEFRA. In the past, it was possible to install a non-Defra certified stove in a Smoke Control Area as long as you only used approved fuels such as wood. However, as of January 2022, the law is changing and stoves that aren't approved will not be allowed to be installed unless they are equipped with a secondary or tertiary combustion system that will drastically reduce the production of particulate matter NOx, carbon dioxide and organic gaseous compounds.

Our Defra approved ranges are also equipped with a mechanism that stops you from closing down the top air vent completely. This can cause the fire to ignite and release smoke into your home. These stoves come with an adjustable air feed that lets you open the top vent a little and still maintain an efficient, safe burn.

Defra Approved Stoves are engineered to burn various fuels, including wood. They burn wood with such efficiency that they comply with the 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 logs, briquettes and pellets. Stoves that have been approved by Defra will be branded with a SE' symbol that stands for Smoke Exempt.

A Defra-approved stove is different from a conventional multifuel stove due to its secondary air vents that heat air prior to it entering the firebox. This pre-heated, heated and pre-heated air ensures that the fuel is ignited in order to ensure a cleaner combustion. It also reduces soot build up and prevents the chimney from becoming blocked. The stoves of Defra also come with internal baffle plates that help to regulate the flames and ensure an even heat distribution.

Defra could impose heavy penalties for anyone who is using an appliance that is not approved by DEFRA in areas that are smoke-free.

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

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

Installation

If you are in a smoke control area then a Defra exempt multi fuel stove can assist you in complying with the rules.

They can burn wood or other fuels, such as coal without worrying about the level of smoke they produce.

Stoves that have been DEFRA approved can reduce smoke levels by using advanced combustion techniques that produce less smokiness. They typically employ an additional stage of combustion, which re-burns some of the waste materials from the first stage, making them cleaner and more efficient. In addition to reducing emissions they also reduce the amount of soot that accumulates in the chimney and flue.

This is a great benefit especially if you live in a smoke controlled zone as it means you can sit in front of a real fire more often and longer, with the additional benefit of lower energy bills. These wood burning and multi-fuel stoves are beneficial to the environment since they release less pollution. They can also be used to burn more materials than other stoves.

A simple kit provided by the manufacturer can make many stoves DEFRA-exempt. This kit alters the air vents of the stove so that they do not close at night. This is called slumbering, and it allows for part-burned combustibles which would otherwise block the flue to escape into the atmosphere. DEFRA approved stoves don't slumber and are therefore much more eco-friendly and less likely to block the chimney.

It is recommended that a HETAS registered installer or a Building Control officer install your DEFRA approved appliance to get the best out of it.
