Powerflush
Terms and conditions

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. After the power flush, the system is full of clean water, and reinstatement to normal operation takes only a few minutes.

The vast majority of power flushes that we carry out are without problem, and result in a cleaner and more efficient heating system, with radiators restored to their original output. However, it is important that you are aware that 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. You should therefore be aware that there may be occasions when, 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.

Additionally, whilst it is rare for a heating system to experience leaks after the power flush process (and the advanced stage of corrosion required for such a situation means that the leak would have occurred imminently even without a power flush), it is not possible to inspect a system internally beforehand, and occasionally we may encounter a leak.

The price quoted allows for a power flush only, and if any of the above or further problems arise

during or after the power flush, then any additional work required would need to be carried out at an additional cost.
