Why do chimneys need a liner?

If you’re hearing about chimney flue liners for the first time, you might be wondering if they’re really necessary. And the answer is, yes they are.

Within this system, chimney flue liners usually serve four main functions:

  • To stop heat transferring into the structure of the chimney, which is important so that the hot air is drawn up from your fireplace or heating appliance
  • To ensure maximum efficiency of your heating appliance, as ventilation is key to allow airflow and avoid a build-up of dangerous levels of carbon monoxide
  • To protect the structure of the building from damage caused by the acidic substances in the flue gases
  • To prolong the lifespan of your chimney and keep your home in optimal condition

Installing a well-insulated chimney liner is a price worth paying to have an efficient and safe chimney system.

6 signs that you need to install a new chimney liner

Here are some common signs that might indicate that your chimney needs lining, or relining:

  1. You have a new heating appliance and the existing flue is too big for it
  2. The flue is leaking smoke and/or fumes into your home
  3. The existing flue is too cold and is not drawing properly
  4. Condensation or tar may be seeping through the walls of the chimney and causing stains on the inside or outside of the building
  5. The existing flue is in poor condition due to erosion or other damage and is causing leakage, chilling and poor up-draught
  6. The existing liner was installed the wrong way up causing tar and condensation leakage (a common issue with chimneys built from 1965 onwards)

8 benefits of installing chimney flue liners

Here are some of the benefits that make the cost of your chimney flue liner a worthy investment:

  1. Chimney liners prevent carbon monoxide and other harmful gases from leaking into living spaces in your home
  2. Most home insurance providers will cover the cost of relining your chimney
  3. Flue liners help prevent any condensation (often associated with gas-burning appliances) from leaking back into the structure of your home
  4. Some insurance policies limit coverage if home renovations are carried out with no improvement made to the chimney
  5. Adding a liner to a chimney with a wood-burning stove or fireplace will prevent condensation that can lead to a build-up of creosote and tar – both highly flammable and pose a significant fire risk
  6. Installing a chimney liner helps you, as a homeowner, adhere to building and fire safety regulations (the violation of which could land you with some hefty fines and penalties)
  7. The price of installing a chimney liner far outweighs the risk of chimney fires
  8. Chimney liners are a cost saver too as they drastically improve heat retention and airflow, which means you’ll use less fuel

Chimney lining costs

Types of chimney flue liner

There are several types of chimney liners available at different price points.

Choosing the right type and quality of chimney liner is important to ensure you have a safe, efficient chimney system.

It’s also worth noting that there are two grades of quality for chimney flue liners:

  • 316 grade – This is the lower-cost chimney liner option. It’s perfectly fine to use if you’re only planning on burning seasoned wood or have a gas heating appliance
  • 904 grade – The more expensive but also more durable option that often comes with a longer guarantee. You’ll need this grade if you plan on regularly burning coal

Here are some of the most common materials used for chimney liners:

1. Rigid stainless steel flue liners

Generally considered to be the entry-level chimney liner, rigid stainless steel chimney liners typically have the lowest price point.

However, being cheaper they also tend to have a limited lifespan guaranteed of 10 years. So you may need to replace them more frequently than other types of flue liner.

Pros

  • One of the lower-cost flue liner options available
  • Can be installed as a freestanding unit (on the inside or outside of your property)
  • Suitable for appliances that burn wood, oil or gas

Cons

  • Short lifespan (many stainless steel liners are only guaranteed for 10 years)
  • Can corrode rapidly with the use of certain fuels
  • Easy to damage during the installation process

2. Flexible steel flue liners

A flexible chimney liner is a great alternative to more rigid types, as it provides a better way to improve the performance of your chimney.

Flexible steel flue liners will expand and contract according to changes in temperature.

They’ll either have a single skin for use with gas appliances, or twin skins made from overlapping strips of high-grade stainless steel  (suitable for wood and multi-fuel appliances).

Pros

  • Flexible liners are generally quicker, easier and cheaper to install than rigid liners
  • Less frequent cleaning is needed due to reduced creosote build-up
  • The liner can be removed for easy cleaning and maintenance

Cons

  • Metal flexible liners have a limited lifespan
  • May suffer corrosion with certain fuel types

3. Pumice  / concrete flue liners

Pumice and concrete chimney flue liners are both made up of pumice, but concrete liners will have some cement blended in.

The advantage of pumice is that it’s a naturally insulating material, which makes it an ideal choice for a chimney liner.

A pumice or concrete chimney liner allows your chimney to quickly reach its optimum temperature. It will also keep the chimney warmer for longer, which reduces the likelihood of condensation and soot build-up.

Pros

  • Lightweight materials are easy to handle and inexpensive
  • Highly insulating allows strong draw and minimum heat loss
  • Helps achieve optimum performance from your heating appliance and reduces your fuel costs

Cons

  • Installation costs are often higher than other types of flue liner
  • Complicated to install for chimneys with bends
  • Repairing damaged or cracked pumice or concrete can be complicated and expensive to repair

4. Clay / ceramic flue liners

Clay and ceramic flue liners (often referred to as clay tiles) have been around since the 1900s and are still a popular choice of chimney liner.

They’re a great option as they can withstand extremely high temperatures without damaging or hindering the performance of the liner.

The clay material itself is relatively inexpensive and, once installed, will last for a good 50 years. However, the installation process for clay and ceramic flue liners is more complicated and expensive to do.

Pros

  • Long lifespan of 50+ years thanks to extreme wear resistance
  • Excellent resistance to acids and other corrosive substances
  • Made of natural raw materials and are therefore easily recyclable

Cons

  • Clay flue liner installation costs can be expensive
  • The rigid shape means they’re not suitable for chimneys with any bends
  • Installation and maintenance work are more complicated than other flue liners

5. Cast-in-place flue liners

As you might guess from the name, cast-in-place chimney liners are installed by pumping a mortar mix into the chimney around an inflated rubber tube, which creates a smooth rounded surface within the chimney.

Once the mortar has fully set, the rubber tube is removed and the liner is left intact. This process creates an excellent liner but makes it the more expensive option to install.

Cast-in-place liners are excellent, durable insulators and have a lifespan of up to 50 years. They’re generally lightweight and also provide a sturdy structure that can help reinforce the existing chimney.

Pros

  • Boost structural integrity of old chimneys making them ideal for chimneys in poor condition
  • Improves efficiency of heating appliances
  • Suitable for use in masonry chimneys that burn all types of fuel

Cons

  • Installation can be complicated and expensive
  • Requires expert knowledge of the casting installation process

6. FuranFlex® flue liners

FuranFlex® is one of the newest chimney lining systems available on the market and uses a glass fibre reinforced thermosetting resin,  which is as strong as steel when set.

It’s most commonly used in listed buildings to bring large open fires back into use or Inglenook fireplaces, where it might not be possible to alter the physical characteristics of the fireplace or chimney structure.

It’s also particularly effective at lining long or bendy chimney flues, like those found in some Victorian houses.

Unlike steel liners, it gives better corrosion resistance, is gas and watertight, and generally comes with a 25-year guarantee (and is said to have a lifespan of 100+ years).

Pros

  • Its versatile nature makes it ideal for complex chimney structures
  • Relatively quick and easy to install
  • Corrosion-resistant and extremely durable with a lifespan of up to 100+ years

Cons

  • One of the more expensive options
  • Not all chimney professionals work with FuranFlex®

FAQs

Does my chimney need a liner?

In new-build properties, all chimneys intended for use with an open fire, wood-burning stove or gas fire need a chimney flue liner to comply with current UK building regulations.

As a general rule, if you have a chimney that you’re using with an open fire or heating appliance then you need a chimney liner.

An inspection by an experienced chimney professional will tell you a) if your chimney has a suitable liner, or b) if you need to install a new flue liner for safety purposes.

Is it a legal requirement to line a chimney?

Current UK building regulations dictate that chimneys in all newly built properties must be fully lined and meet British standards.

In older properties, the regulations state that the chimney must be fit for purpose, which may or may not involve having a chimney liner installed.

To find out if your chimney needs a liner to meet legal requirements, a professional chimney liner installer can carry out an inspection and deem whether your chimney is safe for the intended purpose without fitting a liner.

What type of chimney liner do I need?

Several different types of chimney liners are suitable for different uses and available at different costs.

 

The type of liner you need will depend on the type of chimney and heating appliance(s) you have.

We recommend speaking to an experienced local chimney installer to get their professional advice.

How long will a chimney liner last?

The lifespan of a chimney liner depends on the quality and material of the liner itself, which will also affect the cost.

The average lifespan of a newly installed chimney liner can vary from 10 to 50+ years, so it’s worth considering this when choosing which liner is best for your chimney.

A lower quality stainless steel chimney liners and pumice chimney liners generally have a 10-year guarantee. A more expensive, higher quality stainless steel liner or a Furanflex® liner will be more like 20 years.

Are chimney liners safe?

Chimney liners are safe as long the installation is carried out correctly.  If you’re planning to use an open fire or heating appliance in your home it’s important to follow the manufacturer’s safety instructions.

Chimney liners should also be swept regularly to ensure the flue is clear of blockages or any build-up of creosote or soot.

Does a chimney with a liner need sweeping?

Yes. A chimney with a liner should be swept regularly, ideally at the start and end of the heating season. This is to make sure it’s kept clean of debris such as bird nests and cobwebs, as well as any build-up of creosote.

If you’re burning wood or coal, we recommend having your chimney swept once a quarter, when in use.

For smokeless fuel, gas and oil-burning appliances, your chimney should be swept at least once a year.

Why do chimneys need to be cleaned?

Keeping your chimney clean ensures optimum efficiency of the chimney and flue itself. It also reduces the risk of chimney fires occurring.

A chimney fire can spread extremely quickly and usually starts due to a build-up of combustible substances, such as soot or creosote.

Regularly cleaning or sweeping your chimney will minimise the chances of a chimney fire starting.
