flushing is a more efficient and quicker way of cleaning a central heating
system. It consists of flushing through the whole system using water (and
usually a cleaning agent) at high velocity, but low pressure, so that no
physical damage is caused to the system.
Most people are familiar with the build up of lime scale on the elements of
kettles and immersion heaters in hard water areas in the country, however,
scale formation in closed circuit water heating systems is rarely considered.
Power flushing will break up these hardened deposits and debris, allowing
them to be flushed away easily. This will restore central heating systems to
optimum efficiency and sort out problems that may have been occurring as a
result of scaling, such as banging noises and reduced efficiency.
