What diameter is a boiler flue pipe?
A typical gas boiler flue (or pipe to most people) has a diameter of 100mm, with two different channels for gases to flow. The 60mm central pipe is used to take the exhaust gases outside, whilst the 100mm outer ring is used to bring in fresh air.
How long should a boiler flue pipe be?
As a general rule, a flue should work effectively when it’s up to 10 metres in length. This is usually based on a standard thickness of 60/100mm. For flues that need to be longer than this, it’s a good idea to increase the thickness to 80/125mm to ensure that the gases are able to escape easily.
