Central heating problems? A Power Flush could be the answer!
- Is the system slow to warm up?
- Are some radiators completely or partially cold?
- Do radiators need frequent bleeding?
- Is radiator water dirty or discoloured?
- Radiators with pin hole perforations and leakage?
- Are there 'kettling' noises from the boiler?
- Do you have repeated pump failures?
 Any of these symptoms could indicate that your system has circulation and flow problems resulting from internal corrosion and the subsequent formation of rust, sludge and scale deposits.
A Power Flush can restore circulation and efficiency to the heating system by removing these undesirable products. It purges them from the system, and replaces aggressive water with clean water, chemically trated to prevent future problems.
Fitting a new boiler to an existing heating system?
The high efficiency and compactness of modern boilers, developed to minimise fuel costs and pollution, makes them more susceptable to problems caused by debris in the system water.
Boiler manufacturers insist that heating systems must be thoroughly flushed out before installing a new boiler. A Power Flush is far more effective than traditional methods, and ensures that the boiler installation complies with 'best practice' standards.
Why have your system Power Flushed?
- Cures flow and circulation problems
- Restores system efficiency
- Restores heat output to radiators
- Cleans whole system, including underfloor pipework
- Removes aggressive water; treatment prevents further corrosion
- Cures or prevents boiler noise
- Power Flushing and descaling in only one visit
- Complete process carried out in under 5 hours (depending on system size)
- More efficient that traditional flushing methods
- Minimises boiler warranty problems
How does Power Flushing work?
 The Power Flush pump is simply connected into the heating system, either across the standard circulation pump couplings, across the tails of one radiator, or wherever most practicable.
Power Flushing is a highly effective cleaning operation which works by pumping water at a much higher velocity than usual through the heating system, to loosen and mobilise harmful corrosion deposits, and to suspend them in the rapidly moving water. The process is made more effective by specialist cleansing chemicals and an instantaneous flow reversal device, which creates turbulance in the radiators to optimise 'pick up' of the debris.
Once loosened, the unwanted debris is purged from the system with clean water. 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.
 During the Power Flush process, radiators are individually flushed, without removing or disconnecting from the system, by directing the full output of the pump through each radiator separately.
Power Flushing is not a high pressure operation, and is suiatble for most domestic wet central heating systems. It is carried out with minimal disturbance and disruption to the normal operation of the system, often without disconnecting the boiler or any radiators.
Why do heating systems need protecting?
As soon as a heating system is competed and filled with water, deterioration of the sytem begins. The combination of water, air, a mixture of metals, and even isntallation debris and contaminants, can result in internal corrosion, sludge formation in low flow areas, and scaling of boilers and heat exchangers.
Symptoms include cold panels in radiators, blocked radiators, irritating boiler noises, a longe recovery time after drawing off hot water, an inadequate water supply, and failure of pumps, radiators and valves.
These problems are not inevitable, and good care and maitenance of a system, and addition to the the heating system of a quality corrosion and scale inhibitor will prevent and often cure them.
