about power-flushing

the importance of quality power-flushing

Disappointingly some heating engineers will assume that system contamination is the cause for poor heating performance without thoroughly investigating what the true cause may be, recommending powerflushing as a ‘cure-all’ solution which it definitely is not. We have been asked to powerflush heating systems, which have turned out to only require simple balancing, had we carried on and powerflushed the customer would have paid a great deal more than was necessary to no avail. Similarly powerflushing will not cure piping defects, or undersized pipework. 

Powerflushing plays an important part in restoring older heating systems. It is offfered by most heating companies these days, but not always for the right reasons and is often employed when inappropriate, or ineffective and sometimes when not necessary.

Some systems are not compatible with Powerflushing such as single pipe systems, some micro-bore systems and (unless significant piping modifications are made) semi-gravity systems, unfortunately, whether due to ignorance or unscrupulous selling we still see companies (some large enough to know better!) selling powerflushing on these types of systems. There are cleaning methods that can be be effective on these types of systems, although sometimes re-piping may be the best long term solution. If you have one of these systems we will be pleased to discuss thecleaning options.

A highly effective method

Having said all of the above, when employed correctlypowerflushing can be a very effective method of cleaning and restoring a central heating system. If a system has been in operation for 10 years or more, especially if open vented it may benefit from powerflushing, when a system has been in operation for 20 plus years, even if well installed and reasonably well maintained it is likely that powerflushing will remove considerable contaminants. Unless the system is one of the types mentioned above which are not compatible with powerflushing, we would always recommend it when a boiler is replaced.

Again this is true of many, if not most heating companies today, however the quality of the powerflush can vary greatly. Firstly the equipment employed may vary there are cheaper flushing machines on the market which do not have the power to handle larger or badly comtaminated systems, high volume is required, this is why we use a Kamco CF90 machine capable of handling even the largest domestic systems. In conjuction with this machine we use a Magnacleanse powerflushing filter, which incorporates two large magnetic filters capable of removing large quantities of magnetite from the system.

When considering which company to use to clean yourheating system, we suggest you ask them for their procedures and for details of their equipment and compare them to ours.

The second important factor is the method used. A thorough powerflush can be very time consuming and it is impossible to predict how long a flush will take before starting, as many factors will influence this, but there are certain procedures that should be followed to ensure a thorough power-flush. Many of these are overlooked by those keen to do a fast, rather than a thorough, job.
