Wood Burner Fitting

Wood Burning Stove Installation

Ok, great, so you’ve decided on installing a wood burning stove, well now you need to consider all of the issues involved with the installation.

 

How much does it cost to install a wood burning stove?
Wood BurnerIf you already have a chimney and no additional building alterations are required, installation cost can be as little as £350, our HETAS approved engineer can confirm costs during a site survey.

If you don’t have a chimney then a class 1 HETAS approved twin wall stainless steel insulated liner is required and installation costs would start at around £1500. Planning permission is not normally required. Liner and stove installations should be undertaken by a HETAS engineer to HETAS regulations.

Is My Property Suitable for Wood Fuel Stove Installation?
You should be able to build or convert a chimney, since the most important part of installing a wood fuel stove is the flue vent, which should be designed for wood fuel appliances and have sufficient air movement for the stove to operate properly, existing chimneys can often be used by adding a flue liner.

  • If you live in a smoke control area you should fit a clean burn stove which is approved for use in such areas.
  • You should have somewhere for fuel storage and a local fuel supplier.
  • You need to comply with safety and building regulations in particular Part J of the Building Regulations and Part L related to conservation of fuel and power.
  • Listed buildings or properties in areas of outstanding natural beauty need additional permission from the Local Authority Planning Department.

The Flue Liner
It is important that all the hot emissions from the stove travel up the chimney through an flue, usually with a stainless steel liner, otherwise tar deposits can accumulate in the chimney, or worse, emissions can escape into the property. Building regulations stipulate that a Class 1 Chimney is required, the masonry construction should have at least a 6 inch diameter which is air tight so as not to leak gases. A steel register plate should be used to seal the throat of the stove and to connect to the flue pipe.

Stove Installation and UK Building Regulations
Building Regulations related to stove installation include Part J Combustion Appliances and Fuel Storage Systems and Part L related to conservation of fuel and power. That means that any chimney work including the fitting of the flue liner and or chimney construction is under building control. Often a visual inspection is required to ensure that the chimney is in good order, of proper size and without obstructions. Occasionally a smoke test is required to make sure that the flue is air tight. In addition the stove should be positioned on a plinth of non combustible material which extends around the stove. We recommend approaching the building control department of your local council and Alfred Poppins can do this on your behalf.

Clean Air Act Compliance and Smoke Control Areas
Recent Climate Change legislation requires compliance with Building Regulations Part L related to conservation of fuel and power. If you are located in a smokeless zone there are clean burn stoves which comply with the Clean Air we can recommend the right type of stove and we can still work to your budget.

DIY Stove Installation – Not Recommended, please use a qualified HETAS engineer
Whilst it’s an interesting and challenging diy project, incorrect stove installation can be very dangerous, please be aware that hot fumes from the stove are a fire risk if the stove has been improperly connected with the flue or if the flue itself is incorrectly installed, secondly carbon monoxide fumes can cause suffocation, poisoning and death if they enter closed areas with poor ventilation. If you are installing a wood burning stove yourself, you should at the very least install a fire alarm and a carbon monoxide detector and the installation MUST be inspected by your local authority building control to check it complies with building regulations.

Leaking chimneys
carbonmonoxideLeaking chimneys are caused by the lime mortar disintegrating and the exposed pointing that remains starts to corrode, resulting in smoke leaking through the chimney into rooms, loft spaces or into a neighbour’s flue. Our wood stove fitter’s install flexible liners into leaking chimneys when we install wood burning stoves, so that the dangerous smoke goes up the stainless steel chimney flue.

Leaking chimney flues are one reason to have a flexible liner installed with your wood burning stove. They also make your stove work better because metal conducts heat quicker and makes the wood burning stove draw properly, without a flexible liner being installed by our wood stove fitters, a chimney could start to leak a few years after the chimney passed an integrity test.

Leaking chimneys can build up soot deposits in adjacent flues which pose a real chimney fire risk as well as an obvious risk of smoke inhalation in your bedrooms or your neighbour’s house. Leaking chimneys can be created from annual sweeping which is recommend at least once per year when burning logs and smokeless fuels. This is why we recommend installing a flexible lining system with wood burning stoves into all chimney flues, whether they are leaking or not initially.
