Powerflushes

What is a power flush?
A Powerflush is a method of restoring heating performance to an old heating system, by connecting a reservoir pump into the heating circuit and pumping water at high velocity around the system to break down any limescale & sludge deposits, then pumping the deposits out of the system to a drain, until the system water runs relatively clear.

By doing this, any debris and contamination in your radiators will be flushed out and cleared from your central heating system, restoring it to a higher level of performance.
