Multifuel, Wood burning, Contemporary & Inset stoves
Getting Started, four important points to consider...
When considering the stove package you are looking to put together, there are many things to consider. A stove and its installation is more of a lifestyle choice & project than say a marble fireplace and electric fire. Unlike gas and electric fires heat isn't instant and require a degree of patience particularly in the early days of use. There are 4 main considerations to take into account: current flueing system, looks, usage and the budget available,
If you have a class 1 chimney then they offer the greatest flexibility for what package you can have and a flexiliner can be used to line the flue. If not, then a twinwall system will be required. They are available in black or stainless steel finish. These systems are used most often in modern homes or places like conservatories or orangeries where no chimney breast exists.
Twinwall systems are about 3x the cost of a flexiliner kit which should be considered when considering the budget that will be required for the project if one is needed.
What you want your package to consist of can vary greatly, The most popular combination tending to be a stove with wide window, oak beam, slate or brick chamber, rivern slate hearth. However, there are many variations of each part which can give a completely different look to what you want to achieve. Many still enjoy the look of a traditional fireplace along with a stove. These need to made from stone or solid timbers. The more you want from your package or stove the more this can impact on your budget. A standard stove can do the job wheras investing a little more can often pay dividends in looks & quality of build.
Room size should be a big consideration for the size of stove you choose, there is no point overheating the room just to let the heat out as its too big! There are pros and cons for selecting a cast iron stove over a steel one, many offer both, Imports against British made is a consideration for many or even modern instead of a traditional look. Multifuel may offer versatility but wood is often cheaper and burns cleaner. With laws constantly changing the ecofriendly versions are becoming more popular all the time. The bigger the stove the more it usually costs though.
If you have a class 1 chimney, a decent budget for the project ideally should be between £2500-£3500. There are variables that can flex it either way but generally speaking that sort of budget means you get a decent stove, the full flexiliner kit, fireplace or a beam, chamber, hearths and fitting completed by a competant HETAS engineer.

Moving forward...Before choosing your stove
Considerations - Type of fuel...
Once you have checked your type of flue, putting your preferred package together can commence. There is a wide variety of styles to suit all needs, from the traditional to very contemporary.
One of the first considerations for stove ownership is deciding on which type of fuel you will use – solid fuel (such as coal or smokeless briquettes) or wood. These two fuels burn in different ways, so the designs of our stoves differ to optimise their performance depending on the fuel type. To assist combustion, coal and other solid fuels need air to reach them from below through a grate, so our multi-fuel stoves are designed with this mind. They have a riddling plate, which allows any build-up of ash during the burning process to be removed and allow more air in from underneath.
Wood, on the other hand, burns differently and is best when sitting on a bed of ash. But the most important point to remember with wood burning models is to use well-seasoned wood. Ideally, this means it has been dried for at least six months to remove the majority of any moisture. Another aspect to bear in mind is the space required to store wood, which needs to be approximately 3-4 cubic metres. Finally, it’s important to consider the local availability of your chosen fuel. It’s always best to buy in bulk to ensure it is cost effective throughout the winter, using a local, reputable supplier.
Considerations - Construction of stove...
There are two types of material used for the construction of stoves: cast iron and steel. Both materials provide the warmth and cosiness associated with a stove, but they operate in very different ways.
For many years stoves have constructed from cast iron, making them extremely robust and built to last. The durability comes from the manufacturing process which involves pouring molten metal into moulds to create the desired shape. However, as cast iron is so dense, it can take some time to reach working temperature although, conversely, it retains the heat further into the evening and continues to radiate warmth after the fire starts to die down.
Steel stoves have improved greatly in recent years, and they now offer an alternative option for homeowners. Unlike cast iron, steel stoves are less dense, and subsequently far quicker to heat up.
Selecting the right output for your room is key to a successful installation. Too high an output might result in having to open a window as it’s too hot. Or you might find yourself trying to run the stove at a lower temperature, which can cause ongoing problems with a stove’s operation. So it’s worth using an online ‘Heat loss calculator’ to help gauge what size is best for your home, then discuss specific requirements with a HETAS approved installer. They will also be able to help guide you concerning adequate ventilation for the stove installation.
Considerations - Installation
As stoves are heating appliances, there are Building Regulations that govern their installation. For that reason, we advise all customers to use a HETAS approved installer to ensure all aspects comply with the relevant standards.
There are a wide range of elements required to meet these Regulations, including hearth sizes, flue outlet heights, flue sizes and ventilation requirements to name but a few.
Much of the information will need to be obtained from a HETAS engineer during a site visit. However, there are a few elements you can consider beforehand to gauge how much work is required for your installation,
Do you have an existing hearth? A stove needs to sit on a slab of non-combustible material that protects against any combustible materials underneath, or around the stove, from igniting.
Do you need a chimney liner? This depends largely on the age and construction of your house but, as a general rule, properties built after 1964 will have a concrete or clay liner which won’t require any additional flue lining.
Of course, if your chimney doesn’t have a liner, or you don’t have a chimney at all, a specially designed flue kit can be installed to comply with the relevant Building Regulations.
Are you in a smoke control zone? Many towns or cities in the UK are smoke control areas, where you are banned from emitting smoke from a chimney unless your stove is smoke exempt.
Finally, it’s important to remember the fitting of a carbon monoxide (CO) alarm is also a requirement of Building Regulations.
Considerations - Maintenance
A stove requires regular checks and maintenance to ensure it operates at its optimum level. However, for most stove owners, this is a fairly easy task.
Here are a few of the general maintenance steps you’ll have to carry out as a stove owner:
Check the grate is in good condition and the riddling plate is working correctly (multi-fuel stoves only)
Inspect the firebricks for any damage to prevent any cracking or warping of the stove
After continued use, the fire rope seals might become frayed or damaged and will therefore need replacing
Examine the glass for any cracks, as well as remove a build-up of deposits
Annual sweeping of your chimney will also minimise the risk of soot fires that can cause damage to the chimney
Considerations - Use
How you will use the stove needs to be taken into account when choosing between cast iron and steel. If you are likely to use the appliance regularly throughout the winter for extended periods – i.e. 4-5 times a week – then cast iron is a better option, as it will be more durable over the years. If you only envisage lighting a stove on the odd evening or weekend, a steel stove might be the better choice.
Considerations - Stove size?
The average room temperature for comfort and relaxation is around 21° C; to achieve this you need to supply around 1kW of heat output for every 14 cubic metres of space. To find out the size of your room take the height, length and width measurements. Then multiply them together. For example, if your room measures 5m long by 6m wide and a height of 3m your cubic meters adds up as 90 cu. m. Divide this by 14 and this would tell you that you need a 6.4kW stove.
Please remember this is a rough guide, other factors must be taken into consideration including double glazing, insulation, age of home etc.
An average sized room usually needs no greater than a 5kW output.
The calculation below can also be used as a rough guide for calculating the required output:
Room Width x Room Depth x Height = Y
Divide the answer (Y) of the above calculation by one of the following numbers:
12 (for a poorly insulated room)
15 (for an averaged insulated room)
18 (for a well-insulated room)

Multi-fuel stoves are appliances that are capable of burning a variety of materials other than wood. Apart from logs, a multi-fuel stove can burn smokeless fuels (look for authorised fuels that are approved for use in Smoke Control Areas), anthracite and peat/turf briquettes. The design of these stoves is optimised to accept a greater number of types of fuel and to burn them as effectively as possible. Multi-fuel appliances have a raised grate with moving bars or a central riddling grate and ash pan. Both of these options allow the burning fuel to be de-ashed to maintain effective combustion conditions. Ash is then contained in an ashpan below the grate to enable safe removal.
Many multi fuel stoves incorporate a primary air inlet which introduces air from beneath the grate, these features both facilitate efficient combustion. The heat output of a multi-fuel appliance will be similar, if not identical to that of a wood burning stove – and both types are highly efficient. Many also have Airwash and Cleanburn as standard and, as with a wood burning stove, the introduction of innovative functions and technologies has meant that running an appliance is easier and more cost effective so you can derive greater pleasure from the many benefits and ambience it will give you in abundance.
So, you may well be asking yourself: why should I choose multi-fuel over wood burning? The main advantage is one of convenience: as a multi-fuel stove can burn a range of approved fuels, you will be able to choose from a greater number of suppliers and therefore select the nearest. This will help to reduce not only the amount you spend on fuel but also the time and money you will need to transport it to your home.
Whichever you choose however, it is worth making note that some dedicated wood burning stoves and multi-fuel stoves can be fitted with a kit to enable the combustion of all types of solid fuel, thereby giving you the best of both worlds in terms of fuel availability.
Wood burning Stoves

A wood burning stove is usually built without a fixed grate, but with a flat base: as the wood burns the ashes are collected and when the fire needs more fuel, fresh logs are placed on top. The effect is hugely positive for wood burning because logs combust more effectively & evenly when resting on a bed of ashes, giving you maximum efficiency & heat output from your wood burning stove. When combined with Cleanburn technology, the effect is enhanced further. The introduction of air into the firebox of the stove to combust gases & hydrocarbon particles ensures that your fuel is used as effectively as possible meaning greater value for money & wonderful flames to admire. It is also worth considering the environmental benefits of wood burning. It is regarded as a carbon neutral form of energy as during its growth, a tree will absorb the amount of carbon dioxide roughly emitted when it is burned on a wood burning stove or fire. It is thus a provider of ‘green’ heat. You may also be in a position to maintain your own private wood supply, thereby generating virtually free fuel that is exclusively available to you whenever you need it although bear in mind that logs must be sufficiently dry to burn.
If you have a standard builders opening then our Inset Stoves are designed to be built into a chimney breast leaving only the front visible or can be sat into a stone fireplace for added wow factor. So with the Inset Stoves not only does this give a sense of simplicity to your room but they are also a popular choice where space is limited. They give you a 'window of flame' in your wall and are available in many different types, eg double sided inset stoves, ones with curved fronts, or huge wide letterbox insets with doors that slide up and into the wall. A cassette stove is an inset stove with a second layer of metal around the firebox which forms an air gap around the stove allowing heated air back into the room. Cassette stoves are usually a little easier to install. We offer inset wood burning stoves and inset multi fuel stoves in either contemporary or traditional designs.
