What is the difference between a flue and chimney?
What’s the difference between a chimney and a flue? A flue is the channel, pipe, or tube through which gases and smoke travel from a source of combustion (fireplace, furnace, boiler) to the outside environment. A chimney is, on the other hand, in its simplest definition, the housing that encases the flue.
What flue means?
A flue is a duct, pipe, or opening in a chimney for conveying exhaust gases from a fireplace, furnace, water heater, boiler, or generator to the outdoors. Historically the term flue meant the chimney itself.
Is a chimney A flue?
A flue is simply a passage for conveying exhaust gases from an appliance to the outdoors. A flue may be a duct, pipe, vent, or chimney. An unlined chimney is technically a flue, even though an unlined chimney is a fire hazard.
Can you use a chimney without a flue?
Yes. You can install a wood burning stove in properties without a chimney. Stovax has designed a twin-wall flue pipe system – the Stovax Professional XQ™ range – which allows rooms without chimneys to enjoy the benefits of a wood burning stove.
What is a Class 1 or 2 flue?
Class 1 Chimney – Gas Fires. Class 2 Chimney – Gas Fires. Pre-Fab & Pre Cast. High Efficiency Gas Fires. Balanced Flue Gas Fires.
What does class 1 flue mean?
Class 1. A fire (Gas, Oil or solid fuel) that require a “CLASS 1” flue. By simple definition this is a flue that would be suitable to burn coal in. The most obvious and familiar Class 1 flues are the brick built chimneys that we see around on most older houses.
What are the different flue types?
There are six main flue types, and each can be determined by simply looking at your roof.
- Brick Chimney. The Classic brick built chimney is suitable for all gas fires and stoves in this website.
- Pre-Fabricated. Pre-fabricated flues are suitable for most gas fires and gas stoves.
- Pre-Cast.
- Balanced Flue.
- Flueless.
Can a chimney have 2 flues?
A single chimney can safely have multiple flues inside the chimney, each flue venting an appliance, fireplace, or other device, provided that the chimney was properly constructed, including the necessary spacing or sealant between the individual flues.
Why are there 2 flues in my chimney?
A flue is a venting system, each system needs its own so If you heat your home with oil or gas and have a fireplace you would have two flues. Often times they are in one chimney so if you were to look down the chimney it would be separated into two venting system inside one chimney.
What is a Class 2 chimney?
Prefabricated Flues (Class 2)
They are made up of interlocking metal flue pipes. You can easily identify a prefabricated flue by the metal cowl on the roof, which looks like a thin metal chimney. What fires can you have with a prefabricated flue? You can have electric, gas and gel fires with a prefabricated flue.
Why does my chimney have three flues?
They provide interior thermal mass; they are durable; and they are handsome to behold. Older cold-climate homes often included similar large brick chimneys with multiple flues. This type of chimney is usually located near the center of the house, so that the bricks and the flues stay as warm as possible.
Who is responsible for shared chimney?
The whole of a shared stack can only be removed if both owners are in agreement – if it is on account of defect the cost will generally be split but if it is being done as part of improvement works to one property the owner benefitting from those works will generally carry the cost.
How do you tell if my chimney is capped?
If your chimney extends to the roof, make sure the chimney cap is securely attached to the top of the chimney. If you have a multi-story home or a steep roof, use a pair of binoculars to check the chimney cap from the ground.
Does each fireplace have its own chimney?
Typically, homes that are built after the 1900s have a separate flue for each fireplace; even the furnace and water heater use separate chimney flues. We still quite often see an oil fired furnace venting into a flue with the wood burner, which ignites the creosote and sparks a dangerous chimney fire.
How do you tap into an existing chimney?
You can not tap into the existing chimney. All need completely separate paths, to prevent CO from the downstairs fireplace from venting into your attic. You can add an additional chimney/stove pipe.
Can you use the same chimney?
Depending on the particular circumstances, additional installation requirements may be imposed, or sharing the same chimney flue may not be permitted. If the chimney is an older, typically clay-lined, masonry construction, venting gas-fired heating equipment into it may be unsafe.
Can a boiler flue go through a chimney?
With this being the case, it meant all properties with thick walls could only fit boilers with the flue (a long, flexible metal liner) going up through the chimney. Boilers fitted this way were called open-flued appliances, which meant the boiler took its air from the room and fumes naturally drifted up the chimney.
Can a flue run horizontally?
If you have a combi, regular or system boiler that runs on natural gas, liquified petroleum gas or oil then your home will have a flue pipe. You’ll be able to identify the flue as a white or black pipe installed either horizontally out of a wall or vertically from the roof.
Can I extend my boiler flue?
The flue terminal is about 850 mm long and is normally cut shorter when installed. If yours exits behind the boiler then all that is likely to be needed is a new terminal. Otherwise if 850 mm is not long enough then an extension can be fitted to lengthen the existing terminal unit.
What is the maximum length for a boiler flue?
All of Baxi’s, Main’s and Potterton’s system or combi boilers with a 60/100mm concentric flue fitted can be up to a maximum length of 10 metres. If you find that you do need a longer flue run, then the flue size can be increased to 80/125mm, giving you a maximum flue length of up to 20 metres.
Can a flue be too long?
Flue pipe is too big for the furnace. Excessively large flues reduce the velocity of the combustion products, allowing them more time to dissipate heat through the pipe walls. Flues that were acceptable for natural-draft furnaces are often too large for the new, 80% induced-draft furnaces.
