The Importance of Rapid Flushing Your System


Rapid Flushing System

Your central heating system over time builds up with sludge and debris. This is caused by chemical reaction between dissimilar metals within the system. Copper, brass, aluminium and iron. Chemical inhibitors will slow down the process which produces this reaction, but over time the inhibitor becomes less effective.

All component parts of your heating system are effected by sludge and magnetite build up. Pump, radiators, pipes, valves and especially your boiler. Old cast iron boiler would take this abuse over years with no notable effect, that you would notice. New low water content modern boilers are a different matter, as the build up of these nasties can be seriously detrimental to their health. And more importantly your pocket with expensive repairs, reduced life span and reduced efficiency.

A single power-flush will remove an average of 3kg of sludge and other deposits from an ageing heating system. Where the system has incorrectly cold feed and vent pipe, or where no inhibitor has previously been added, anything up to 7kg of sludge can be removed.

The Magnacleanse rapid flush system is 5 times more effect and will remove virtually all suspended iron oxide particles and debris in one pass. What enters the filter is retained and prevented from re-circulating, by a powerful magnetic field.

Magnetic Filter

Now you don’t need to have an expensive power-flush every couple of years with an inhibitor top-up, as once the Magnacleanse rapid flush is done then a Magnaclean filter can be installed to continue protecting your system. Then when it comes to having your annual boiler service the filter is cleaned, inhibitor topped up, and the protection continued.

We believe that rapid flushing and installing a Magnaclean Filter is a must for modern central heating systems and boilers. We therefore incorporate them in any new boiler quote, for your future peace of mind. Even if you have had a new boiler installed recently we still can carry out a rapid flush and install a Magnaclean Filter. Better late than never. Prevention is better than cure and it will definitely improve your system.

Why Your New Boiler Installation isn’t Saving You Money

   You must be kidding! You’ve been told your new boiler that has just been installed is going to reduce your gas bill. Or so your told. The new condensing boiler is very efficient, so why am I telling you it won’t be, when all the papers, advertising, and heating installers are telling you otherwise. You may have had a new heating system installed, had it flushed along with your radiators. You may have had inhibitor added, but unless you had a magnetic filter fitted, you may as well have kept your old boiler.

    Black Sludge. Black iron oxide, better known as sludge, builds up in your heating system, causing boiler breakdown, decrease in circulation, cold spots on radiators and at worst blocked pipes. The initial cleaning of your heating system and added an inhibitor will put your system back to near full efficiency initially, but as time passes, the sludge will return. The inhibitor becomes less effective and a further flush will be required. Not cost effective in your eyes so it’s unlikely to happen, is it.

   You may have your Boiler serviced regularly; but rarely your system. How many service engineers flush your system annually? They might top up your inhibitor, but that’s not good enough. If you liken this to the service on your car. The engine is tuned, the oil is changed along with the filter. Why; because the oil in your car becomes thick with sticky, gooey contaminants, and lowers the effective running of your car, wearing out parts prematurely. It’s no different to your central heating system. The boiler is the heart, the engine, with water running through it’s pipe work , instead of oil. You need to remove and clean out that sludge that builds up within the system and your radiators. Your not going to have a flush every year, but you can have a filter fitted, which can be easily cleaned when your boiler is serviced.

   Black oxide build up can reduce the efficiency of your system by as much as 15%,. According to the experts, that measure these changes. Case studies indicate that even though heating systems have had a powerflush, with the fitting of a magnetic filter, reveals sludge still exists. Flushing had not removed it all. In addition by fitting a magnetic filter it can increase the efficiency of your existing heating installation by 6%. Again more money saving on your gas for the future. Case studies have also revealed that over a two year period the results have been so good, where magnetic filters have been fitted, compared to installations without them, housing associations are making it a matter of course, in fitting them.

   A magnetic filter is a small vessel, usually fitted to your central heating system, on the return pipe going to your new boiler. It has a couple of valves, which are turned to isolate the filter, enabling the removal of the black sludge. It doesn’t have to be fitted on just new boiler installations, as it can be installed at any time, and it’s not overly expensive.

   A new boiler life span is anything from 10 to 15 years, depending on the manufacturer’s quality of product. It seems common sense to prolong it’s life to the full. Consider having a magnetic filter fitted to ensure you have an efficient heating system, with lower breakdowns, and lower gas bills.

   Moggridge Plumbing Limited recommends the installation of a magnetic filter such as Magnaclean or Fernox F1, in association with their Magnacleanse power flush. Contact us now on 0206412240. Or register your interest at, and we will contact you.
