When it comes to wood burning stoves, there are a variety of flue liners to choose from and as with any important purchase, it can be difficult to know which is best. Any chimney specialist will advise you that buying a flexible flue liner is the best choice for any wood burning stove. They are the easiest installation option especially if your chimney has any bends or dips.
Flexible flue liners are strong, stable and able to hold up under the pressure and force of being pulled up and installed in the chimney. Not only that but they can also withstand extreme temperatures for prolonged periods of time on a regular basis during colder months of the year. As a result of these fluctuations, you will also find that the liner will become damp, something which the stainless steel can easily adapt to.
The high-quality materials used will ensure that your liner will protect your chimney and subsequently prolong its life. It is also important that you get the right size liner for your project, too big or small and you will have to start from scratch. The measurements for this can usually be carried out an installation specialist.
There are two different grades of flue liners to choose from, the 904 and the 316. The main difference between these grades is the quality with the 904 being made of a higher grade of stainless steel. Whilst it is more expensive, it will last a lot longer and will not rust or corrode over time. If however, the 904 grade is not within your budget, the 316 can be equally as effective but will as mentioned not last as long. It is a grade that is intended to mainly burn seasoned dry wood and so will work well in a wood burning stove.
In terms of installation, your first and most important step is to have your chimney professionally cleaned. There are many specialists that can do this for you to ensure there is no residual soot or debris that could obstruct the flue during the installation. Once the liner has been installed it will then have to be checked to ensure it meets UK Building Regulations.
This inspection intends to check that the liner has been properly installed using the correct sizing and that it is not obstructed in any way. Your chimney may also need other work done to properly secure it during the liner being fitted. Another check you may want to have done is a smoke test to ensure that every part of the chimney is smoke tight. In order to do this, you will need to have access to your chimney in your home and on the roof.
Regardless of what flue liner you choose for your stove, it is important that you have it properly installed and examined by a professional. Ensuring that there is efficient combustion in your stove will not only guarantee the safety of your home but most importantly it occupants.
