Specialists in central heating system sludge and debris removal
Prevent costly repairs and premature boiler failure
Fix issues: central heating taking long to heat up or radiators cold at the bottom
Why is Power Flushing Needed?
RAK PowerFlushing Ltd, led by Richard Knight, specialises in unblocking radiators and restoring heating system efficiency nationwide. With 25 years of experience in offshore commercial plumbing, Richard ensures thorough and professional power flushing services, eliminating sludge and debris to prevent blockages and system failures.
Sludge and debris accumulation in today's radiators and central heating systems is a significant issue. When not removed, these contaminants can build up in radiators, pipework, and heat exchangers, causing severe blockages.
This build-up diminishes heat transfer and can damage pipes, radiator valves, and heating control servo valves. In some cases, it can even lead to the premature failure of the boiler.

Restore Heating Efficiency with Power Flushing
Our primary service, power flushing, is designed to remove sludge, debris, and other contaminants from customers' heating systems. Over time, these build-ups can clog radiators, pipework, and heat exchangers, reducing efficiency and risking costly damage.
Our expert power flushing service thoroughly cleans systems, restoring heat transfer, energy efficiency, and reliability.
By improving system performance, power flushing also helps extend the lifespan of heating equipment, reduces energy bills, and ensures a warm, comfortable home environment.


Chemical Cleaning
For systems that require a more intensive cleaning process, we offer chemical cleaning services. This method involves the use of specialised chemical products to break down and remove stubborn deposits that standard power flushing might not fully eliminate.
Chemical cleaning can significantly enhance the longevity and efficiency of heating systems, providing a deeper clean for heavily contaminated systems.
System Balancing with Thermal Imaging Camera
Proper system balancing is crucial for ensuring even heat distribution throughout your property.
At RAK PowerFlushing Ltd, we use state-of-the-art thermal imaging cameras to accurately diagnose and balance the heating systems.
This advanced tool allows us to identify and address any uneven heat distribution, ensuring every room in your home or business is comfortably heated.


Great service from RAK PowerFlushing. Our central heating had never been flushed (that I'm aware of) and the boiler was experiencing problems. Richard was great at explaining the problems (and demonstrating with his thermal imaging camera) After a very long day Richard managed to clean the system and remove a lot of debris as well as fit a magnetic filter. He topped this of with a water quality test. All the radiators are working perfectly and there are no cold spots.

RAK PowerFlushing have just completed a complete overhaul and power flushing of our central heating system. You couldn't meet 2 nicer people than Richard and his son. They are very professional and explained in detail what they were doing, and gave good advice when parts needed replacing. They have an excellent work ethic, working from 8.30 in the morning until 9.30 at night, and I am sure they would have stayed longer until the job was finished to their very high standards.
