Sludge and scale
Black Oxide sludge forms continuously in all unprotected central heating systems as a result of corrosion. It will also harden into scale on the
hottest surfaces of a system (i.e the boiler heat exchanger causing it to make knocking and kettling noises). This also prohibits efficient heat
transfer.
it is advised to get it checked to be safer than sorry.
Benefits of a Powerflush
After your system has been power flushed it will benefit instantly- your system will really appreciate the new lease of life you have just given it!
Internally your system will be running much more efficiently, effectively and cleaner, you may also notice immediate improvement externally
such as reduced boiler noise or more heat in your radiators. It is perhaps the long term benefits that best describe the usefulness of power
flushing:
• Efficiency restored back to optimum levels
• More reliable heating
• Rust protected central heating system
• Scale protected central heating system
• Lower fuel bills
