What is power flushing?

Power flushing is the most efficient and effective method of cleansing a central heating system. The principle is to create a powerful fresh water flow under controlled conditions to remove debris from the system. By connecting the power flushing unit to the heating circuit in place of the system pump, boiler or radiator the circuit can be thoroughly cleansed of limescale and corrosion debris. When used in conjunction with a Fernox Cleaner F3 a typical power flush can be completed in 3-4 hours.

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 system or this could 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%.

Fernox

With over 40 years experience in the field of domestic water treatment Fernox have developed a range of products to help maintain the efficiency of central heating systems and to ensure their long term protection against the damaging effects of corrosion and limescale.

Fernox have continually invested in research and development and have recently launched the new Powerflow Flushing Machine. With all the latest design features the Fernox Powerflow Flushing Machine will ensure a fast and effective system clean.

Fernox Cleaners F3

• Removes sludge and scale and restores heating efficiency in existing systems
• Removes flux residues and other installation debris
• Eliminates boiler noise
• Non-acidic neutral formulation (environmentally friendly)
• Conditions the system prior to adding a Protector
• Compatible with all metals and materials commonly used in heating systems

System protection

Whether pre-commission cleaning new systems or restoring existing systems, all systems should be protected against any further attack from corrosion or limescale after cleansing by using a properly formulated corrosion and scale Protector.

Fernox Protectors

• Provides long term protection against corrosion of all metals
• Prevents build-up of black sludge
• Saves on fuel bills through improved efficiency
• Prevents sticking pumps
• Effective scale reducer
• Stops frequent venting of radiators
• Compatible with all metals and materials commonly used in heating systems
• DWTA accredited products

Fuel wastage
Without treatment, corrosion debris will accumulate in the boiler causing increasing limescale deposits, reduced heat transfer and up to a third of a fuel bill going to complete waste.

Boiler noise
This increases in frequency and intensity as deposits of sludge and scale build up in an unprotected boiler.

Cold spots
The familiar cool low central area of a radiator indicates a build-up of black sludge sediment that restricts flow and reduces heat.

Frequent venting
When the top of a radiator is cold during operation, either air or hydrogen is to blame. Hydrogen gas builds up as a by-product of electrolytic corrosion and is flammable (due caution is required).

Pump seizure and failure
The abrasive and magnetic properties of black oxide sludge increase shaft and bearing wear in pumps causing them to stick or fail.
