Winchester Boiler Flue Experts

For your heating system to function without issue, it is vital that all components are working correctly. One of the small yet crucial features of your setup is the boiler flue. This component is a pipe that is connected to your boiler and pumps exhaust gases out of your home. Making sure that this pipe is both clean and functional is essential as it ensures the continued running of your heating appliances, and prevents harmful gases from posing a health and safety risk.

Here at No1 PHD, our Winchester heating team have been working on heating systems of all sizes for many years. Our staff are confident in being able to work on everything from boiler installations to radiator repairs, so rest assured that boiler flue servicing or repairs will be no problem. If you’d like your boiler flue inspected, be sure to reach out to a member of our staff today on 08006906777

What is a Boiler Flue?

Boiler flues are an understated yet essential part of every heating system. They are responsible for carrying away harmful chemicals and gasses that would otherwise remain in your boiler and eventually spread throughout your home. These fumes come from the fossil fuels that are burned to keep your heating system running. Flues are connected directly to your boiler and carry away the bi-products of these fuels through a pipe that runs out of your home.

Combination, system, and regular boilers all have flues attached as standard. You can find it either sticking out of the side of your home or through the roof. When looking at the pipe, you’ll see for yourself the gasses coming out. To ensure that your flue continues to work efficiently, it is vital that it is maintained regularly. This work mostly requires cleaning that should be carried out every now and again to make sure there’s no clogging to block gases from exiting your home.

While they don’t require intense upkeep, flues are still subject to damage, so it is important to inspect them every so often to ensure they’re working. A key sign of a damaged flue is black stains on your boiler, which indicates a leak. To reduce the chance of damage occurring to your flue, you must invest in the correct type of model. The types available for homeowners include:

  • Vertical
  • Square
  • Round
  • Horizontal

Before leaving, we’ll test your flue to ensure that everything is functioning correctly and offer useful maintenance advice.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
