What is a central heating powerflush?
A powerflush is a deep clean of the central heating system, using a powerful machine to flush out debris. Christopher Plumbing Services can advise whether a powerflush would be suitable for your system.
A powerflush can save energy and money
Debris from corrosion and limescale can accumulate within the central heating system (boiler, pipes and radiators) as soft sludge or hard flakes. This debris reduces heating efficiency and can cause blockages. It might even cause the boiler to shut down!
A clean central heating system runs more efficiently, has fewer breakdowns and lasts longer – reducing day-to-day and long-term expenses.
When is a powerflush needed?
A powerflush might be recommended when installing a new boiler, after installing a completely new central heating system or when older systems have symptoms like these:
Increased fuel usage, causing up to 30% wastage!
Boiler noise and failure
Radiators have cold spots
Radiators have cold tops and need frequent bleeding
Pump noise and failure

Powerflushing aftercare
After powerflushing, a water treatment conditioner or inhibitor can be added to the system to prevent future problems.
Please note that after any work that involves the draining of your heating system you may need to bleed any remaining air from the system for up to two weeks after work is complete.
How to bleed the central heating system
- Turn off the heating system.
- Using an appropriate bleed key, release any air from the radiator bleed valves until only water is released.
- Close the bleed valves.
- Turn on the heating system.
- Repeat this process daily until no more air is released.
- If it is a pressurised system, it will be necessary to pressurise the system after bleeding air from the radiators.
