Can a boiler flue go through the roof?

| 173 views

The short answer to this question is ‘yes’. All manufacturers these days, for room sealed boilers, give you the option of a horizontal or vertical flue system. Firstly, let’s see what a boiler flue is. The flue is a pipe and resembles something like a dedicated chimney for the boiler. Residue such as carbon monoxide gets emitted through the flue. As Leon explains in the video for our Boiler Solutions blogs segment, a vertical flue system is an option for all boilers. However, it would be governed by the clearances expected in the manufacturer’s instructions. One will also need a proprietary plate or weathering slate to put a boiler flue through a roof. The manufacturer would specify these too. This blog attempts to provide an overview of the question ‘can a boiler flue go through the roof?’

It does not need to go out of a roof

Apart from a roof, flues can also extend outside through the wall. A boiler flue plays an important role. Subsequently, it expels harmful gases and ensures that none seep back into the inside of your home. Like a chimney extends through your roof and sends out smoke, the flue does the same. The flue that sticks out of the top is classified as a vertical flue. On the other hand, those that extend via a wall or on the side of the property are known as horizontal flues. But, keep in mind that it does not need to go out of a roof only.

Unfortunately, these fumes are also not good for the environment, but our homes have to rely on these flues. It is to ensure that no harmful gases linger inside your home. They do the same job regardless of whether you go for a vertical or horizontal flue. If you have an engineer drop by one day to get a service or some other service, you can enquire from them.

Why is my boiler flue dripping?

Boilers that are present in our homes are mainly condensing ones. Correspondingly, this signifies that the exhaust creates heat using the energy produced. In this case, there is nothing that goes to waste when it comes to the energy created. This heat is what helps to reheat the water. In turn, this hot water goes back into the system. So, the residue that goes out through the flue would be colder than that of non-condensing boilers. The cooler it is, the chances are for acidic condensation to collect in the flue. Eventually, it is these remnants that cause the flue to leak. On the other hand, do give our blog on how long does it take to fix a boiler leak? a read.

How long can a boiler flue be?

Getting various brands, models or manufacturers recommended would require you to consider what you need. So, before you decide on the length, get advice from the boiler manufacturer preferably. At the same time, stay updated on the services that we offer, among them being boiler installation. Visit the website to learn more.

Each manufacturer has its variations. At the same time, their specifications would differ from the others. So, those specs will also depend on the boiler you have or plan to get. However, an average length of 10 metres is generally set to do the job. So, the longer the flue, the thicker it would need to be. It ensures that the residue would easily navigate its way to the outside.
