What is ‘ Power flushing ‘, also called ‘Jet flushing ‘ or ‘ Hard flushing’, of a central heating system? Well pretty much what it sounds like. Water is very corrosive. As it circulates, deposits and debris build up. In ‘ the good old days ‘ this wasn’t too much of a problem with large bore tubes and big heat exchangers. In today’s energy conscious world things are very different. Modern boilers must be over 90% efficient which requires a heat exchange matrix of very fine waterways. In this situation rusty sludge is the last thing you need!
We use the Kamco CF 90 Quantum power flushing pump acknowledged as the best in its field. Put simply it pumps water through your heating system to clear all the debris accumulated over time. More accurately it is a skilled procedure that we have been trained ( by Kamco ) to operate. It is a high velocity, low pressure pump which uses hot water, mobilising agents and high power magnets to remove all deposits and leave the system absolutely clean. We would stress that this procedure must be carried out by a trained technician or your system could be damaged.
So when is a power flush needed?
Most importantly if you are fitting a new boiler to an old system. In order for a manufacturer to fully accept the terms of a warranty in line with the ‘Benchmark’ standard, a system must be appropriately flushed. Power flushing is often the only way to achieve this. Not only that but your high tech appliance may quickly get clogged up, thus lowering the efficiency and costing more on bills.
If your system is up and running but you have any of the following symptoms;
radiators cold at the bottom,
some radiators heating up, but others not,
radiator water black,
system slow to heat up,
radiators need frequent bleeding,
unpleasant boiler noises,
‘combi’ boiler gives erratic temperature delivery,
slow heating of hot water cylinder,
repeated pump failure,
then it is likely unwanted deposits are causing the problem. A power flush followed by the addition of a corrosion inhibitor and a magnetic filter to capture rust will put you back on the road .
