Chemical Inhibitors for Central Heating SystemsFernox, Sentinel Chemical Inhibitor & Additives by Fernox, Sentinel & others added to Central Heating Systems ( New and existing systems ) undertaken in the Peterborough & Cambridgeshire Area by energy efficiency qualified heating engineer and Gas Safe registered (previously corgi gas) engineer.
Be wary of engineers NOT Gas Safe registered performing "work" on boilers whilst working with central heating.
Do I need a Central Heating System Inhibitor ?Untreated water in a wet central heating system will naturally corrode metal components.
Particles typically bond to the interior surfaces of components, often causing wear and premature failure of pumps and valves. The heavier types of debris can settle at points of low water flow causing blockages and upsetting the balance of the system, resulting in loss of boiler efficiency and system effectiveness.
An Inhibitor is a chemical mix that should be added to the central heating system ( new or existing ) to prevent corrosion and prolong the life of the system,
Adding corrosion inhibitor to new or existing centeral heating systems is vital, and a lack of corrosion inhibitor in a system invalidates warranties on boilers and systems.
![]() An untreated system can exhibit a variety of symptoms such as radiator failure, boiler failure, loss of efficiency, boiler noise, black water when bleeding the system etc.
![]() Any of the problems described can be attributed to a lack of initial cleansing and failure to add inhibitor when the system was new, or maintain the level of inhibitor after draining down a system. Ensure that the system has been properly cleaned and adequately treated. A cleaning treatment may be applied first, in more severs cases the system may have to be powerflushed.
