Sentinel has for some time been successfully selling its System Filter, providing a solid, reliable and cost effective solution to the need to shift all types of system debris from domestic heating systems.

It’s quick and easy to fit and will last the lifetime of the system it’s fitted on. The Sentinel System Filter, unlike other filters available, removes all debris types – magnetic and importantly non-magnetic - protecting the boiler and other system components from damage caused by debris and ensuring that the heating system maintains its optimum efficiency levels. It’s easy to clean and maintain, and with no magnets to remove, no need to dismantle it and no valves to shut off, it’s been very well received by installers and heating engineers looking for a simple response to the removal of debris from a domestic heating system.

The Sentinel system filter has been designed to work alongside Sentinel X800 Jetflo cleaner.  Sentinel products comply with the BS7593 Code of Practice for correct water treatment in Domestic systems, which states that: “Filters which collect magnetite may be beneficial as part of the flushing procedure. These should be used with a chemical cleanser to mobilise the magnetite and aid its transport to the filter”.

It is recommended that installers cleanse the system with Sentinel X800, then fit a Sentinel System Filter. X800 and the Sentinel System filter have been specifically designed to work together in mobilising magnetite and other forms of heating system debris, to enable its removal from the system, restoring system efficiency.

The problem:

There have been a number of reports in recent months emanating from social housing providers in particular, suggesting that a number of boiler heat exchangers have become blocked due to dirt particles building up between the heat exchanger plates.

Two London & Quadrant Housing Assocuation owned properties and ten owned by Enfield Homes were identified to carry out ‘system cleans’ using Sentinel X800 Jetflo cleaner followed by treatment with Sentinel X100 inhibitor/protector.  After the clean had been undertaken in each case, Sentinel System Filters were fitted in all properties to the heating systems on the return to the boiler, to provide long term protection from, and removal of, any circulating debris – magnetic or non-magnetic, left in the system.

  

The results: These results clearly show the benefits of fitting a Sentinel System Filter.  Although the systems were cleaned, flushed and inhibited, there still remains the potential of some level of suspended solids still remaining in the heating system.   The use of a Sentinel System Filter removes this debris effectively and will continue to remove it for as long as it is in place, resulting in a very low level of suspended solids in the re-circulating water.

Summary:              

It is clear that fitting a Sentinel System Filter as part of the water treatment regime offers the permanent, on-going level of protection required by social housing providers in the heating systems in the homes they own and manage. Having the Sentinel system filter in place eliminates unwanted call backs to contractors or a providers own direct workforce, to remedy problems associated with debris in circulating water in a domestic heating system.
