Power Flushing

Power flushing in South Woodford

Need your central heating system professionally cleaned to maximise its efficiency? We undertake power flushing (central heating system flush) across South Woodford and all surrounding areas including Walthamstow, Wanstead, Leytonstone and Woodford.

A power flush is a cleansing process, which removes deposits of sludge, rust and any other debris from your central heating system in order to improve its effectiveness. Cleaning your heating system has a number of benefits: it can resolve problems you may be experiencing with your heating system, improve the efficiency and lifespan of an existing boiler, or protect a newly installed boiler. For further information read our guidance below or contact us to get in touch. We are always happy to answer any questions you may have.


Why you should consider a central heating system power flush

The core component of every heating system is the boiler. When a boiler is renewed, the Boiler Manufacturers’ Benchmark scheme requires that the system be thoroughly cleansed, according to the BS7593:2006 Code of Practice. Currently, the best industry practice is considered to be to conduct a system power flush, which includes a thorough clean of the entire central heating system in order to ensure that it is operating at its most efficient level.

What exactly is a power flush and how important is it?

Powerflushing is the fastest and most effective way to flush central heating systems and involves minimal disruption and dismantling. At Beales Services, we use the best-in-class, purpose-built power flushing pumps, designed to cure hot water circulation and boiler noise problems caused by the accumulation of sludge, corrosion deposits and limescale which are found in most dated, or older central heating systems. 

How does power flushing actually work?

The power flushing pump is temporarily connected to a heating system during the flushing process. The high water velocity, combined with instantaneous flow reversal, dislodges and mobilises sludge and corrosion deposits. Having loosened the debris, the pump expels it from the system to waste, using a high-velocity flow of freshwater. Radiators are individually flushed without removal or disconnection from the system. After the power flush, the system is full of clean water, and reinstatement to normal operation takes only a few minutes. 


Important things to consider before booking a power flushing service

A power flush can be extremely effective in cleaning systems that have corrosion problems as a result of a design fault, but we strongly recommend that any such design faults be rectified before power flushing commences. The success of a power flush will depend on the level of heating system corrosion that has occurred beforehand. The process will cure most circulation problems, but cannot undo the corrosion and gradual decay that has led to the need to power flush the system.

Whilst it is rare for a heating system to experience leaks after the power flushing process, it is not possible to inspect a system internally beforehand, and the need to use flushing and dispersing chemical (see Part L of the Building regulations) for effective cleansing means that occasionally we may find a leak.

The advanced stage of corrosion required for such a situation means that the leak would occur imminently even without a power flush. We believe that it is better that it occurs whilst we are present to remedy the problem, rather than for it to arise over a weekend or whilst the house is unoccupied.

Does the age of your central heating system matter when getting a power flush?

Systems that have been neglected over a period of time, or have not been treated with effective corrosion the inhibitor may have severely compacted corrosion debris, in the pipework, radiators, or boiler, and it is possible that even after the power flush, some radiators may still not be fully effective, or boilers on the margin of failure may cease working due to sludge and debris later breaking loose and collecting in the heat exchanger.  We will assess the condition and age of the system prior to recommending a power flush and in some instances, where a power flush is not advisable, we will offer alternative suggestions. 

It is important to note that the vast majority of power flushes that we carry out happen smoothly and without any problems, and they also result in a cleaner and more efficient heating system, with radiators being restored to their original output, at the most optimum level of performance.
