Twin Wall Chimney System
We only use the best quality products
All our lining and twin wall systems are HETAS approved. Consumers should be aware that much cheaper, inferior products are readily available. Cheap systems have a short product lifespan and due to the inferior materials there is a risk of damage during installation, potentially leading to leakage of combustion gases.
Cost of installation
If you already have a chimney in sound condition with straightforward access and no need of building works then having your wood burning stove installed won’t cost a fortune.
The price of installation increases if;
• Access is difficult
• There’s a need for structural alterations/ chimney repair
• The existing chimney is unsound and needs lining.
What if there’s not an existing chimney at the property? In this situation a twin wall system is generally the answer, this will pass out either through the wall or out through the roof to expel gases.
We can advise you about any necessary planning consent.
What is chimney lining?
The function of a chimney is to safely remove the products of combustion from a fireplace or appliance to outside of the building, without causing any danger to the occupants of the house. Lining systems are designed to replace the flue in an existing chimney with the dimensions appropriate to the appliance. Insulation may be added or integrated into the new flue system to improve efficiency.
Why line chimneys?
Chimneys are lined for a number of safety related reasons. Whilst modern chimneys may require re-lining, systems that predate 1965 will often require a modern lining solution for the following reasons:
• The flue may have lost integrity, leaking smoke into rooms.
• Tar can seep through chimney walls causing staining.
• Lining plus insulation improves the operation of appliance and flue.
• Defective flue systems may be eroded and rough, causing resistance to flow the of gases, resulting in poor up-draught.
• Some appliance manufacturers specify smaller flue systems for efficient operation.
Twin wall chimney system
A twin wall chimney system is a popular alternative to a conventional chimney. If the house does not have a chimney, or if the stove needs to be located in an area of the house where there is no chimney. Then this is a great alternative. A twin wall chimney system is essentially a pipe which acts as a chimney coming from the stove to outside, passing out, either through the wall or through the roof to expel the gases from the stove.
In some cases planning permission will needed to install a twin wall chimney system. we can advise you regarding planning requirements. Please see the diagram ‘Twin wall Chimney System’ for a typical system.
