To Power Flush Or not to Power Flush! That is the Question!
A broken down boiler or noisy radiators that need regular bleeding usually indicate that your central heating system needs a good clean.
Before the winter sets in it is even more important to make sure your heating system is in full working order so that it serves you well over the colder months.
Making sure the system is serviced by a qualified professional is vital and this should be arranged well in advance of the winter season because plumbing and heating professionals are usually inundated with work during that time and the wait for repairs or new installations can be a long one.
But you should not wait for your annual service; if you notice any problem signs with your heating system then get in touch with your plumber immediately. Quite often the system will quite simply need cleaning and if so, your engineer will probably suggest a Power Flush.
What is Power Flushing?
Power Flushing is a powerful technique for cleaning central heating systems. It can improve heating system performance by flushing out sludge and scale, optimizing the heat output of radiators and promoting energy efficiency.
Power flushing can solve heating problems and prevent boiler and pump failure and can even provide lower fuel bills due to an increase in boiler efficiency. This is because the action of power flushing improves the circulation through the pipe work so the radiators and boiler do not have to work so hard.
Who should I chose to Power Flush?
Choosing a good contractor to carry out your power flushing job is very important because a skilled approach and lots of experience is needed to maximize the efficiency of the job. You will find that the longer-established companies will employ methodical techniques to isolate and concentrate on problem areas so that you are left with an optimized central heating system that won't let you down during the cold winter months.
When hiring a plumber to carry out Power Flushing work on your heating system make sure that their work is fully guaranteed for a year and that you will receive a certificate confirming that pH levels and cleanliness within your system correspond with industry standards.
Power Flushing for new heating systems.
If you are having a new heating system installed then you should be aware that most boiler manufacturers will not guarantee any new boiler if the system is not chemically cleaned. The British Standards and the Benchmark demand thorough cleaning of the heating system, and Power Flushing is the favored method.
Why Power Flush For winter?
Power Flushing is a powerful method used to clean heating systems. It can improve efficiency and give you peace of mind that your winter warmth won't be jeopardized. It can also save you money on fuel bills!

Central heating system power flushing
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.
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 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.

The price that we have stated allows for a standard power flush only and if any of the above or similar problems arise during or after the power flush we will not hold ourselves responsible in any way.
Any further work required would be carried out at an additional cost.
