System flushing

Welcome to General Gas, your go-to destination for expert gas boiler services. When it comes to ensuring the longevity and efficiency of your new gas boiler system, we offer two specialized flushing techniques: Magnetic Flushing and Powerflushing.

Understanding Sludge Deposits

Sludge deposits, often encountered in gas boiler systems, are the result of untreated water or poorly designed systems. Over time, dissolved metals accumulate within the system, forming a thick sludge. This buildup, if left unchecked, can compromise the efficiency of your boiler. Our flushing techniques – magnetic and powerflushing – are designed to effectively remove these deposits, ensuring your system operates smoothly and efficiently for years to come. Choose General Gas for a comprehensive solution to sludge-related challenges in your gas boiler system.

Magnetic Flushing

Experience the efficiency of our less invasive technique with magnetic flushing. Large magnets are strategically fitted onto the boiler circuit, allowing them to attract and capture sludge deposits before they settle in the boiler. This straightforward and quick process ensures a clean system, promoting optimal performance.


Reserved for systems with blockages, powerflushing is the key to resolving issues effectively. Using high-velocity pumping, we disperse blockages, making it a more intensive yet highly effective procedure. Although more time-consuming than magnetic flushing, powerflushing is indispensable when addressing stubborn blockages, ensuring your system operates at its best.

End Result

Regardless of the method chosen, our skilled technicians guarantee that your system will be in perfect working order upon completion. To further enhance its durability, we add an anti-corrosion inhibitor, providing comprehensive protection for your investment.
