Powerflushing

Why does my central heating need a Powerflush?

Rust occurs in central heating systems producing a black sludge. In hard water areas lime scale builds up (just like in your kettle) causing the following problems.

Cold Top

Radiators cold at the top & need bleeding due to gases; a by-product of rusting.

Cold Bottom

Radiators cold at the bottom due to black sludge.

Little or No Hot Water

Little or no hot water due to blocked pipes.

Blocked Valves

Radiators cold all over due to blocked valves.

Boiler Cutting Out

Boiler cutting out and no circulation due to blocked pump.

Irritating Boiler Noise

Irritating boiler noise from sludge or lime scale build up, a warning sign of imminent costly problems.


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.


What happens during a Powerflush?

The power flushing pump is simply connected into the heating system, either across the standard circulator pump couplings or across the tails of one radiator, or wherever most practicable.


Power flushing is a highly effective cleansing 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 a specialist flow reversal device, which creates turbulence 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 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 and disruption to the normal operation of the system, often without disconnecting the boiler or any radiators.


What will I get after a Powerflush?

Working hot radiators and reliable hot water. Rust protected central heating. Efficient central heating. Lower fuel bills. Peace of mind.


Fitting a new boiler to your existing central heating?

Modern boilers have smaller components which are easily blocked by sludge and debris in existing or even new central heating systems. Boiler manufacturers insist that heating systems be thoroughly flushed before installing their new boilers.Unflushed systems have resulted in premature failure of boilers and led to cancelled warranties. Check your boiler warranty.
