FAQs

HETAS are the official body recognised by Government to approve solid fuel domestic heating appliances, fuels and services including the registration of competent installers and servicing businesses.

All of the Installers here at Dorset Stove Installations Ltd are HETAS registered and have therefore undertaken very stringent training required for installing wood burning stoves to Building Regulations and home insurance requirements.

It is really important that the stove you choose has the correct heat output for the room it is located in.

Here at Dorset Stove Installations we always recommend that a survey is also carried out by our accredited stove installers who can conduct a site survey to ensure you receive the most suitable sized stove for your property.

There are several reasons to use Wood as your fuel source. It’s currently the cheapest fuel on the market and is carbon neutral. Essentially, when you burn wood, it releases the same amount of carbon as the tree absorbed whilst it was growing. Additionally, wood can be reproduced by replanting and replacing trees which were already harvested. This allows the Co2 cycle to be maintained.

Wood must be burnt as efficiently as possible in order to reduce the carbon levels down to zero. The majority of the leading stove manufacturers have therefore focussed on manufacturing extremely efficient stove systems.

A perfect log should be seasoned in order to reduce the moisture content to around 20%. This process is completed by allowing natural air to dry the logs for up to two years in a properly constructed log store.

If you burn wood with high moisture content, you generally end up with blackened tar smoked stove windows, which isn’t desirable when trying to achieve a clean burn.

Kiln dried wood is available to purchase and generally has a moisture content of around 20 per cent. That is the level recommended by stove manufacturers. Kiln dried wood can also minimise problems with stoves and flues.

Wood burning stoves are more environmental friendly as the amount of carbon dioxide released into the atmosphere is the same as that absorbed by the tree during growth. For optimum results from a wood burning stove, logs should be seasoned for 2 years or more with a moisture content below 20%. This will not only give twice the output of freshly felled timber but help avoid a build up of tar in your flue and can extend the life of your stove. A wood burning stove is also designed to burn wood more efficiently than a multi-fuel stove.

Multi Fuel Stoves come with a riddling grate and an ash pan that allows you to riddle the excess ash through the bottom of the stove and into the ash pan below the grate, making the stove extremely easy to clean.

Wood-burning and multi-fuel stove brands and ideas There are a huge range of stove brands, such as Stovax, Acr, WoodWarm, Yeoman and Heta, and a variety of and designs. Here are some of the types, styles and brands of stoves available, from modern stoves to traditional wood-burning stoves. Traditional and modern stoves A wood burning stove can be a lovely focal point in a living room, and wood logs create a traditional feel. Previous Next Multi-fuel stoves Multi-fuel stoves are also called mineral-fuel stoves. They can burn wood, smokeless fuel and coal. There are differences in the way these fuels burn, and not all multi-fuel stoves are optimised for burning all compatible fuels with equal efficiency.

To burn efficiently, coal needs air to reach it from below. Multi-fuel stoves have a grate for the fuel to sit on, making them ideal for coal. Some also have a riddling plate that allows you to remove any ash that's built up, letting more air through from underneath.

Wood, on the other hand, burns best when sitting on a bed of ash (also called a firebox, which is where the fuel burns), with air circulating from the top.

Because of these differences, a multi-fuel stove may not be optimised for burning both types of fuel. Ideally, it’s best to work out what type of fuel you want to burn and what you have access to first, and then base your buying decision on that. The Stove Industry Alliance (SIA) found that 77% of people that have a multi-fuel stove only burn wood. But if you are planning on only ever burning wood, getting a dedicated log burner is advisable. However, if you think you may not have regular access to wood, or are keen to have the flexibility to burn both, then a multi-fuel stove is a good option. Multi-fuel stoves may not be optimised for burning both types of fuel If this is the case, look out for a multi-fuel stove that has primary and secondary (sometimes called airwash) air vents. These allow you to control whether more air circulates from above or below, depending on the type of fuel. Also look for a stove that will allow you to remove the grate, so wood can be burnt on the base of the stove, instead of the grate. If you have a multi-fuel stove and live in a smoke-controlled area, you will only be able to burn smokeless fuel - such as anthracite coal. For more information on what you need to consider when buying a stove, take a look at our expert advice on how to buy a stove.

Wood-burning stoves run solely on wood logs, pellets or chips (although chips are really only used for large buildings, such as community centres). There are two types of wood-burning stoves: log burners and pellet stoves. Log burners (or wood burners) are the most popular, and usually used as stand-alone room heaters for one room. Pellet stoves are more commonly used to heat entire houses. They're also usually larger and more modern looking. Log burners If you're buying a stove to be more eco-friendly, wood is a carbon-neutral fuel. Unlike coal, where the processing of it will have an impact on the environment. There's also a lot less manufacturing involved in logs than there is with pellets and chips - or indeed none if you collect already fallen wood yourself. However, you'll need to factor in either drying time or cost. The cheapest fuel for your log burner is wood that you have collected or bought that still has a high moisture content. But to make it burn efficiently and safely, you will need to leave it to dry out - ideally for around one to two years. Which means you will also need the space. Alternatively, you can buy ready-dried wood, but this will cost a lot more. If you live in a smoke-controlled area, you will need a Defra-exempt stove to burn wood. For more information on sourcing wood, drying it yourself and prices, as well as our videos on lighting wood and multi-fuel stoves, see our guide to using a stove.

The main benefit is efficiency and running costs. The amount of fuel that you use, compared to the amount of heat that you get in return and what that heat will cost you to produce is naturally a concern for most customers.

The truth is that open fires are incredibly inefficient with one study showing that they can actually make the rest of the house colder because of the amount of combustion air that they need to consume, including most of the warm air the fire is creating. Open fires, at best, operate around 20% efficiency compared with efficiencies of over 80% for some modern stoves. You should save between half and three quarters of the wood used to run open fire, Quite the saving if you have to buy your wood. You will also get much more heat output per fuel load than from the same load in an equivalent open fire and the stove's heat is also very controllable. Heat from multi fuel stoves and wood burners are also cleaner and therefore kinder to the environment because of the combustion process.

Stoves are much safer when properly operated compared to open fires. The stove's heat-resistant glass will stop any potential sparks jumping out into the room and prevent any lighted fuel from rolling out.

Regular sweeping is vital to remove blockages and soot. This prevents fires and allows deadly combustion gases to be safely vented through the chimney. Clean chimneys burn more efficiently, which will save you money, as well as helping to preserve the environment.

You’re stove can be fitted as a free standing unit in a room using a twin wall flue system that can take the flue pipe out of a external wall or roof, Or into a existing chamber and chimney. It will need to sit on a hearth and have the required clearances around the stove. All details on clearances can be found in Document J of the Building Regulations.

This smell and smoke is the paint curing on the stove. This is a common and perfectly normal thing to happen with a brand new multi-fuel stove. It can be quite a strong smell and can look quite hazy but this is not to be mistaken with smoke. We recommend you open a window when first lighting the stove, and don’t worry because it will only last 2-3 burns.

Ecodesign is the European-wide programme to lower emissions. It is due to come into force for stoves in the UK in 2022. SIA Ecodesign Ready stoves will meet the Ecodesign requirements and are available now.

The PM emissions limit for Ecodesign is 55% lower than for DEFRA exempt stoves.

SIA Ecodesign Ready stoves are designed to reduce PM emissions by burning wood more efficiently and completely.

No - there is nothing in the Clean Air Strategy which makes reference to this. Any appliances which are currently fitted will be able to continue to be used as normal.

No, however the type of stove which will available for sale may change. It’s most likely they will have to be DEFRA-exempt appliances. This is actually good news because it means a great choice of fuels (both wood or smokeless) in any area. Whereas currently, they are restricted to just smokeless fuel if you do not have a DEFRA-exempt appliance.

Stoves in themselves aren’t polluting - it’s the way some people use them. The truth is that very few people are shown how to use a stove, so they rarely burn efficiently until they either ask for help or have their flue swept. Unlike gas or oil, wood is a renewable energy source and, when burnt correctly, can be a very efficient way of heating your home.

Again, the Government isn’t planning to ‘ban’ appliances but a new effcient stove is a smart move purely from a financial point of view. You’ll get more heat from your fuel and also help reduce emissions into the environment.
