Wolf Heating Power Flushing

Central Heating Power Flush throughout Lancashire and Merseyside

Why buy new radiators when a simple, clean power flush could improve your central heating?

We regularly come across poorly performing central heating systems that show signs of corroding. This is mainly due to poor flushing or no flushing at all when new boilers were installed or upgrades were made to the central heating system. Corrosion can be lead to poor heat up times of radiators, leaking combination boilers (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
  • Central 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!
  • Radiators release unpleasant smell when bled!
  • Leaking radiators from pin holing in the metal

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 central 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 cleans 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 central heating 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.

A Power Flush is also an excellent way to pre-commission clean new central heating systems, to remove excess flux, swarf and other debris, together with the grease and oil used to prevent the 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 central heating 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 are often mobilised by alterations to the central heating system and/or its piping. These debris may then accumulate in the boiler's 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 a Power Flush is not performed when altering your central heating system you may well find that your high efficiency boiler's SEDBUK A or B rating could be reduced to a C or D rating. This makes the cost of installing a high efficiency boiler a waste of money and may result in early failure of the boiler, possibly within 2 to 3 years. This would not be covered by the manufacturers warranty in these circumstances - whilst some manufactures do offer a 10 year warranty on their heat exchangers, this will only honoured if it is working with correct water treatments.

How does a Power Flush work?

The power flushing pump is simply connected into the central 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 central 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 central heating system contains fresh clean water and reinstatement of the system to normal operation takes only a few minutes. A Power Flush of your central heating system will not remedy design or mechanical faults, which should be rectified. However, in many cases a Power Flush will cure the problems caused by such faults.

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 aluminium 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 and most up to date Kamco equipment when performing a power flush. We also use the latest technology filters to remove more dirt per pass than conventional flushing.

Our latest and most powerful machine pushes more water through central heating systems than standard machines, effectively dislodging more sludge which we flush out to waste. We analyse the flushed water on completion using a TDS meter to compare the old contents of your central heating system with water from your kitchen tap in parts per million!

Finally, we perform a PH test to for a neutral PH, ensuring no residual cleaning fluids are left in the central heating system.
