Power Flushing, Jet Flushing and Hard Flushing are all expressions used in the heating trade over many years to denote the process by which heating systems are forcibly cleansed using water at high velocity, but low pressure, so that no physical damage is caused to the system.
The process can be made even more effective with the addition of powerful cleansing and mobilising agents such as FX2 and Hyper-Flush from Kamco.
The objective is to restore systems with circulation and boiler noise problems caused by sludge and corrosion deposits to optimum operation. Power flushing removes these deposits and the problems that they cause.
Power flushing, in conjunction with a System Pre-clean, is also an excellent way to pre-commission clean new heating systems, to remove excess flux, swarf and other debris, and the grease and oil used to prevent rusting of components before use.
It is prudent to power flush a heating system immediately before fitting a new boiler to an existing system to prevent possible future problems. Many systems are found to contain corrosion and sludge, even if no flow problems have yet shown themselves. Existing debris is often mobilised by alterations to the system or piping and the increased efficiency of the new boiler, and may then accumulate in the boiler heat exchanger, causing noisy operation, reduced efficiency and, in extreme circumstances, failure of the boiler. The high efficiency and compactness of modern boilers, developed to minimise fuel costs and pollution, means that they are more susceptible to problems caused by debris in the system water.
Why Power Flush
Is Your heating system old? Yes! Then invest in a power flush rather than a new heating system
Why? Because you will save money.
How? Answer the following questions
Is your boiler over 12 years old?
Does your boiler make a kettleing noise?
Does your radiator collect a lot of air?
When you bleed your radiators is the water black?
Are there any cold spots on your radiators?
Do your thermostatic valves stick?
Are you changing your pump often?
Does your pump stick the start of every heating season?
If you answer yes to any of these questions you may require a power flush. Your heating system is not working properly it is inefficient, you are using more fuel than you should be, can you afford not to do something about this now? Your system is producing iron oxide (Rust).
Clearflow® Power Flushing
The Clearflow power flushing process is a versatile, easy to use and highly effective method of flushing heating systems. By utilising Clearflow system flushing pumps, heating systems can be purged of sludge, scale and corrosion deposits with minimal dismantling and disruption.
How does it work? The Clearflow power flushing pump is simply connected into the heating system, either across standard circulator pump couplings, across the tails of one radiator, or wherever most practicable. The powerful flow, combined with instantaneous flow reverser device, will dislodge and mobilise deposits and flush out to give you clean efficient system
