Power Flushing

Power Flush Services Across South Woodford, Walthamstow, Woodford and surrounding areas

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 get in touch. We are always happy to answer any questions you may have.

Central Heating System Power Flushing Important Information & Guidance

 

The core component of a heating system is the boiler. When a boiler is renewed, the boiler manufacturers’ Benchmark scheme requires that the system be thoroughly cleansed to the BS7593:2006 Code of Practice. Currently, best industry practice is considered to be to power flush the system.

 

Power flushing is the fastest and most effective way to flush heating systems, and involves minimal disruption and dismantling. We use purpose built power flushing pumps, designed to cure the circulation and boiler noise problems caused by accumulations of sludge, corrosion deposits and scale which are found in most ageing central heating systems.

 

The power flushing pump is temporarily connected into 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 fresh water. Radiators are individually flushed without removal or disconnection from the system. After the power flush, the system is full of clean water, and re-instatement to normal operation takes only a few minutes.

 

Disclaimer

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 which 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 a 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.

 

Systems which have been neglected over a period of time, or have not been treated with an effective corrosion inhibitor, may have severely compacted corrosion debris, in the pipe work, 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. 

 

PLEASE NOTE: The vast majority of power flushes that we carry out are without problem, and result in a cleaner and more efficient heating system, with radiators restored to their original output.
