Power Flush throughout Lancashire and Merseyside
Why spend thousands on new radiators when a simple, clean power flush could improve your central heating.
Just recently we have come across a few bad central heating installations showing signs of corroding, mainly due to poor flushing or no flushing when installing new boilers or upgrades of a central heating installation. Leading to poor heat up times of radiators, leaking combi boilers, diverter valve failures, pressure drops, and poor hot water performance.
Does your heating system have these symptoms?
- Radiator water black with iron oxide sludge
- Heating system slow to warm up
- Cylinder has poor hot water recovery time between usage i.e. showers
- Cold spots in the middle of the radiators
- Combination boilers being unable to deliver constant hot water at a stable temperature
- Combination boilers showing signs of water leakage constantly
- Combination boiler pressure gauge keeps dropping below 1 bar setting
- Unpleasant boiler noises
- Repeated central heating pump failure
- Radiators need frequent bleeding! With un-pleasant smell! When you do bleed them
- Leaking radiators from pin holing in the metal

Combi Boiler Flush
Customer reported poor hot water in the shower - Power flush to boiler and radiators cleaning and restoring hot water performance.
Sludge Tank Build Up
Customer reported cold radiators - Typical sludge build up over a period of years due to no inhibitor.
Sludge Removal
Examples of what a power flush can remove in a poorly maintained system.

Power Flush
Customer reported British Gas would not change parts until a power flush had been completed to treat poor water condtion - A modern combined Potterton Powermax boiler with unvented hot water tank.
Results of an Incorrect Boiler Installation
British Gas advised customer he required a power flush on his 3 year old system due to incorrect commissioning during installation.
Benefits of power flushing:
- Lower fuel bills due to more efficient heating system
- Savings of up to 25%*
- Increases system life of radiators and boiler
- Quieter boiler operation due to lime scale removal
*Dependant on the condition of the original system.
Power flushing will clean a central heating system internally improving radiator performance and heat output
What is Power Flushing?
There are thousands of ageing central heating systems with circulation and boiler noise problems caused by the accumulation of sludge, corrosion deposits and scale, but traditional methods of flushing just don't get rid of all the debris, and problems often quickly return. Power Flushing is an expression used to denote the process by which heating systems are forcibly cleansed using water at high velocity, but low pressure, so no physical damage is caused to the system. The process can be made even more effective with the addition of powerful cleansing and mobilising agents.
Power flushing is also an excellent way to pre-commission clean new heating systems, to remove excess flux, swarf and other debris and the grease and oil used to prevent rusting of components before use.
When To Carry Out a Power Flush
It is prudent to power flush a heating system immediately before fitting a new boiler to an existing system to prevent possible future problems. Many systems are found to contain corrosion and sludge, even if no flow problems have yet shown themselves.
Existing debris is often mobilised by alterations to the system/piping and the increased efficiency of the new boiler, and may then accumulate in the boiler heat exchanger, causing noisy operation, reduced efficiency and, in extreme circumstances, failure of the boiler. The high efficiency and compactness of modern boilers, developed to minimise fuel costs and pollution, means that they are more susceptible to problems caused by debris in the system water.
If this is not done a HI efficiency boiler with a SEDBUK A or B rating could be reduced to a C or D SEDBUK rating, making the cost of installation a waste of money and resulting in early failure of the boiler possibly within 2 to 3 years. This would not be covered by the manufacturers warranty in these circumstances, some manufactures offer 10 year warranty on there heat exchangers but only if working with correct water treatments.
How does it work?
The power flushing pump is simply connected into the heating system, either across standard circulator pump couplings, across the tails of one radiator, or wherever most practicable. The powerful flow, combined with instantaneous flow reverser device, will dislodge and mobilise deposits and corrosion which resist traditional system cleaning methods.
Once the corrosion and sludge deposits have been loosened and mobilised, fresh clean water is forced through the heating system, pushing the contaminated water out through a full bore dump valve to waste. During the process, radiators are individually flushed, without removing or disconnecting them from the system, by directing the full output of the pump through each radiator separately.
At the end of the flushing process, the system contains fresh clean water and reinstatement of the system to normal operation takes only a few minutes. System flushing will not remedy design or mechanical faults, which should be rectified, but in many cases it will cure the problems caused by these.

Employ a Trained Engineer to Perform Your Power Flush
It is advisable to employ a trained engineer to carry out your power flush because an untrained person can easily ruin your central heating system by, for instance, using an incorrect solution to clean a boiler containing an alumnium heat exchanger. View the Kamco web site to see if your boiler has an aluminium heat exchanger. If it has, make sure FX2 isn't used to clean the system!
Wolf heating uses only the latest, most up to date Kamco equipment when performing a power flush. We use the latest technology filters to remove more dirt per pass than conventional flushing, our latest powerful machine pushes more water through than standard machines which effectively dislodges more sludge which we flush out to waste replacing this with clean tap water, we analyse the water on completion using a TDS meter to compare the contents of your system with the water from your kitchen tap! In parts per million! With a final PH test to make sure of a neutral PH, checking no residual cleaning fluids are left in the system.
