Without care and ongoing maintenance your new central heating system will gradually deteriorate over time as impurities build up within the circulating water. Every day water is circulating through the hot water pipes and all of the radiators. If there or impurities get into this system they can lead to chemical changes within the pipes and the circulating water which can lead to the build-up of debris or clogging of various components. Combi boilers are prone to the effects of building impurities and sludge within the system.

There are many products on the market which help to reduce the effects of corrosion and the build up of scale or sludge within your central heating system. These are often applied annually or every two years to ensure ongoing protection. You do not need an expert to do this as if products are simply added to the circulating water although the process of doing this is different according to which type of system you actually have.

If your system is severely sludged or if you regularly hear boiler banging you should first apply a product which will remove this contamination. A Powerflush can also help to remove these items and restore the water circulating within your heating system to its original condition. The Powerflush will need to be carried out by an experienced plumber as they will have the equipment and you will not.

After the powerflush you need to add corrosion inhibitor to the system. If you do not do this you have wasted your time and your money as the system could be back to the same level of corrosion in a short period of time.

In a conventional condensing boiler system this inhibitor can be added via the expansion tank which is often found in the loft. As the liquid within your heating system gradually expands and contracts the contents of the header tank will be mixed within the circulating water.

As an alternative you can add the inhibitor via a radiator. The inhibitor manufacturer should supply with the adaptor to enable you to inject the fluid into the radiator. Read the instructions carefully before you attempt this. if you are searching for these system protection products look for “Sentinel” or for “FERNOX” as these are some of the leading brands with proven products.

As with all maintenance requirements, a little tender love and care will keep your system running happily for many years to come and an efficient system will save on your heating bills. Overlooking the need to protect the circulating water within your central heating system could be a costly oversight, reducing the life and efficiency of the system both of which will cost you money in the longer run.

if you have a new central heating system installed or get a replacement gas boiler make sure that you ask the boiler installed what the system protection requirements are and when these should be applied to the system. The boiler manufacturers will make recommendations concerning this refinement and it is best that you diarise the dates when you should be checking the system.

    Search online for Fernox or Sentinel

  • Paula Gallo says:

    I am under a BG home care agreement #400.
    Is this maintenance work covered by the agreement?

    I have none DIY skills and would prefer professional care. If BG agreement does not cover this, could you provide the service at a reasonable price?

  • Boiler Systems says:

    Putting the inhibitor into the system is not covered by the agreement but we wish to help and have contacted you direct with some options to solve your problem.

  • Tashfeen Mogul says:

    I need to know which is the BEST additive to remove iron corrosion from inside the radiators.How many hours in a day,also,how many days,does the fluid need to be in.Thanks.

  • Boiler Systems says:

    We are sorry but we do not publish a comparative review of the corrossion inhibitors / cleansers. The main product brands on sale in the DIY stores are all effective products and should perform the cleansing task they outline.
