A Powerflush (or power flush) is an efficient way of removing the sludge and dirt that build up inside your central heating system over time. Most systems develop this sludge over time, there will be more in older systems.


The following are some of the problems that could be avoided with a Powerflush as it removes the Magnetite sludge from your system :


• Cold Radiators

• Boiler Deposits

• Heating Pump circulation problems

• Pipe Blockages

• Internal Corrosion

• System blockages

• Noisy systems


As a result the benefits of a professionally delivered Powerflush could be :-


• Increased pump life as your central heating pump handles clear water instead of sludge


• Curing radiator cold spots so that the full surface of the radiator heats your room


• Improved central heating system efficiency so reducing fuel costs in future years


• Clearing the boiler heat exchanger to stop banging noises (kettling) and prolonging the boiler life


• Reduces Hydrogen gas build up which can lead to radiator corrosion and reduced heat output


• Clearing your system of contaminated water which could lead to internal heating system corrosion


A Powerflush machine is used also with an magnetic power flushing filter which helps prevents re-circulation of debris through the boiler we also use a combiheat power flushing heater which increases power flushing efficiency  these are used to complete the  task at the highest possible standard. It is connected to your system and the central heating water is routed through the machine where it filters out the contaminants. The Powerflush literally flushes the new liquid through your central heating system. Once the task is completed the Engineer will refill your central heating system adding a corrosion inhibiter to prolong its operating life.
