Power Flush and Magnetic filters

Power Flush and Magnetic filters work in helping the efficiency of your heating system. Here at Ability we look at the idea behind these devices. Once a magnetic filter is installed, the idea is that corrosion within a sealed wet central-heating system produces sludge – which can block up boiler heat-exchangers, pumps and radiators – and that because this sludge is ferrous in its nature  (in that, it sometimes results from iron or steel corrosion), it can be trapped by a powerful magnet and this is what the filter does. Our team recently carried out tests on systems in Orpington, Kent and East Grinstead in West Sussex.

This theory is very much true. But sludge can also result from the corrosion of copper, zinc or aluminium components as well as existing debris or chemicals. This is nonferrous, and will not be caught by a magnet. So this is why a power flush is recommended.

Ideally, your central-heating system should not contain any sludge anyway, because it should be dosed with corrosion inhibitor from the beginning after its installation, unless of corse it is an old system that was installed before the introduction of these chemicals and procedures or a previous installer did not correctly carry out the work. We have come across this in the last 3 months in Crowborough Near East Sussex and Dunton Green in Sevenoaks Kent.

This is easy to do, but some heating engineers do not routinely install inhibitor or even check for its presence, preferring to sell magnetic filters to their customers instead. This is why adult Ability we always carry inhibitors and regularly introduce them into your system.

This is of a concern to us at Ability, because we know that some boiler manufacturers, when called out on warranty visits to your home or claims, will sometimes carry out testing to the system water for inhibitor, and they may decide that if the inhibitor concentration is not adequate, then this invalidates your  warranty on the boiler. At Ability, we are sure to see that this is not the case for you, our customer.

Power Flush

The central heating Power Flush procedure is completed by one of our Heating Engineers connecting our special Power flush machine to your central heating system

The Power flush machine pumps high velocity/low pressure water around the system to remove loose debris from the system causing blockages and restricting flow.

The introduction of high strength chemicals further aids the Power flush process, dislodging and removing dirt, rust and harmful corrosive deposits from the system.

Each radiator is then isolated and flushed individually to ensure the system is left completely clean and blockage free allowing your system to run smoothly.

The whole Process of the powerflush is carried out with minimal disturbance and disruption to the normal operation of the system, often without disconnecting the boiler or any radiators.
