Power flushing
RCB Plumbing provides professional power flushing services for homeowners across Sutton, Surrey and South London.
Why choose a Power flushing?
We help remove sludge, rust and debris from central heating systems so they can run more efficiently and more reliably. If your radiators are slow to heat up, have cold spots or your system is not circulating properly, we can assess the issue and recommend the right type of system clean.
With experience across a wide range of domestic heating systems, we take a practical approach and only recommend power flushing where it is genuinely needed. The aim is simple: cleaner system water, better circulation and a heating system that performs as it should.
Benefits of power flushing
Power flushing can make a noticeable difference to the performance of your heating system, especially where sludge and debris have built up over time.
Improved heat circulation - Helps hot water move more freely through the system.
Warmer radiators - Can reduce cold spots and improve radiator performance.
Better energy efficiency - A cleaner system does not have to work as hard to heat the home.
Lower risk of breakdowns - Removing built-up debris can help protect key components.
Quieter operation - Can reduce noise caused by poor circulation and trapped sludge.
Longer system life - Keeping the system clean can help reduce wear over time.
If your heating feels uneven, slow or unreliable, power flushing can often help restore performance and improve overall efficiency.

Chemical flushes
A chemical flush is a heating system clean that uses specialist chemicals to loosen sludge, rust and other deposits inside the system. It is often used where there are signs of contamination, but a full power flush may not be necessary.
This type of flush can help with common issues such as partially cold radiators, dirty system water, poor circulation and heating systems that are not working as efficiently as they should. It is also a useful option when preparing a system for repairs, upgrades or ongoing protection.
The process usually involves adding cleaning chemicals to the central heating system and allowing them to circulate so they can break down deposits inside the pipework, boiler and radiators. The system is then drained, flushed through with clean water and refilled, with inhibitor added where needed to help protect against future corrosion.
Adey Magnetic Filter Flush
An Adey magnetic filter flush is a targeted way to remove magnetic sludge from a central heating system. It uses a magnetic filter to capture iron oxide and other debris before it can continue circulating around the boiler, radiators and pipework.
It is especially useful where there are signs of dirty system water, repeated sludge build-up or uneven radiator performance. It can help protect components such as pumps, valves and heat exchangers, while supporting better circulation and cleaner system water.
This type of flush is often suitable for systems with an existing Adey MagnaClean filter or where one is being fitted as part of ongoing heating system protection.

Frequently Asked Question
How long does a boiler installation take?
Most standard boiler replacements take 1-2 days to complete. A straight replacement can often be completed in a single day, while system changes or relocations may require additional time.
Which boiler is best for my home?
This depends on your property size, hot water demands, and current system. Combi boilers work well for smaller homes with limited space, while system or regular boilers may be better for larger properties with higher hot water demands.
What happens to my old boiler?
We handle the removal and environmentally responsible disposal of your old boiler as part of our service, ensuring all materials are recycled where possible.
How long will my new boiler last?
With regular annual servicing, a quality modern boiler should last 10-15 years. We recommend joining our boiler care plan to ensure your new system operates at peak efficiency throughout its lifespan.
What is the warranty booster care plan?
Our Warranty Booster Care Plan includes 2 years of complimentary servicing, priority breakdown response, and a dedicated helpline. It also helps retain your full manufacturer warranty.
Can you help me choose the right boiler size?
Yes. We assess your household size, usage, and heating demands to recommend the right boiler model and kW rating for maximum efficiency.
