POWER FLUSHING SERVICES IN NEWARK
There are several reasons why your Central Heating System would need Power Flushing or a Descale; Rust occurs in all central heating systems producing a black (iron oxide) sludge and in hard water areas, lime scale builds up in combination boilers; just like in a kettle causing the following problems:
- when bleeding radiators a dirty black/brown water confirms that there is system corrosion
- Radiators that are cold at the bottom is due to black sludge
- Radiators that are cold all over due to blocked pipes and valvesand need bleeding due to the gases, a by product of rusting
- Radiators cold at the top
- An irritating boiler noise from sludge or lime scale build up, a warning sign of imminent costly problems
- Little or no hot water due to blocked heat exchangers and blocked pipes
- Boiler cutting out and no circulation due to a blocked pump
Power Flushing or Descaling your Central Heating System will remove the debris and will guarantee the efficient operation of your system and provides long term protection; consequently saving on household bills too.
The cleaning and treating of central heating systems
All new systems should be pre-commission cleansed in accordance with BS:7593 and Benchmark. This ensures flux residues, excess jointing compounds, mineral oil and other contaminants that can be found in the system following installation, and that can effect the performance of the system or cause component failure, are removed.
It is important when installing new boilers into old systems that all sludge is first removed from the systemor thiscould accumulate in the new boiler and lead to premature failure. Additionally, in hard water areas existing systems will have accumulated limescale together with corrosion deposits in the heat exchanger, which could easily have reduced the boiler efficiency by over 5%.

Benefits of Power Flushing
. Cures flow & circulation problems
. Restores system efficiency
. Restores heat output to radiators
. Cleans the whole system including under floor pipe work
. Removes aggressive water; treatment prevents further corrosion
. Cures or prevents boiler noise
. More effective than traditional flushing methods
. Power Flushing will clean a central heating system internally improving radiator performance and heat output
What Happens During a Power Flush?
The Power Flushing pump is simply connected into the heating system either across the standard circular pump couplings, across the tails of one radiator or wherever most practical. Power Flushing is an 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 cleaning chemicals and an instantaneous flow reversal device, which creates turbulence in the radiator 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 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.
Power Flushing is not a high pressure operation and it is suitable for most domestic wet central heating systems it is carried out with minimal disturbance & disruption to the normal operation of the system often without disconnecting the boiler or any radiators.
Successes of Power Flushing
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 dispensing chemical for effective cleaning means that we may occasionally 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.

Labour, Chemicals and Power Flushing Machine
How long does it take?
It normally takes a days Labour to Power Flush 7 - 10 radiators
Over 10 Radiators would mean a return visit on the next day
Customers should be aware that they would be with out heating over night
