A few simple precautions can avoid your system having problems like sludge build up and pinhole leaks.
Cause of corrosion
Air getting into the system accelerates deterioration as oxygen is one of the essential requirements for corrosion. You’ll know if air is stepping into because the radiators will need bleeding to urge obviate the air on a frequent basis.
Where the air gets in though is another matter.
It can enter through sort of routes, but the foremost common are through the feed and expansion cistern within the loft, the vent pipe which hangs over it or a leaking joint beside the pump.
Unfortunately, whilst it’s possible to identify these, it’s always employment for knowledgeable heating engineer to put it right.
Testing for corrosion
It’s an honest idea to feature a corrosion inhibitor to scale back the gradual deterioration of the system. Test a sample of water from your system annually to ascertain how corrosive it’s. Place the sample in an old jam jar and put a shiny steel nail in it. Remember to not use a galvanised nail or the test won’t work. Put the lid back on and leave the jar for every week approximately. If the water has turned orange and therefore the nail is rusty, the water has an excessive amount of oxygen and can be corroding the within of your system within the same way. You’ll therefore got to put an additive into the system to scale back this. adding corrosion inhibitor
Adding corrosion inhibitor
Read the manufacturer’s instructions carefully and add the acceptable amount of the anti-corrosion liquid. With an open vent system, this is often done by adding to the feed and expansion cistern. For a sealed system, you’ll buy a cartridge of inhibitor which may be injected in via the air bleed valve on a radiator – again, you ought to carefully follow the manufacturer’s instructions for this.
