Boiler noise results from localised boiling of the water. This happens when the inside surface of the boiler becomes too hot due to scale or baked- on sludge deposits.
All systems over five years can suffer noise and new boilers in old systems are especially vulnerable. Add Fernox Boiler Noise Silencer F2 and / or de-scale the boiler with Fernox DS40 System Cleaner and protect with Fernox Protector F1 or Protector + Filter Fluid.
Leaks in water systems can result from external frost damage, dry solder joints, accidental perforation during maintenance or decoration, or internal corrosion. Sealing internal leaks (central heating systems only) Small leaks, including pressure drops on combination boilers and other sealed systems, can be repaired using Fernox Leak Sealer F4. Each Leak Sealer F4 product treats 100 litres or up to
It is an easy to use dip strip that tests central heating systems for the correct concentration of inhibitor, to ensure that the system is fully protected and sludge and debris is prevented from forming and building up.
Power Cleaner F8 is pH neutral and is not acidic, therefore no neutralisation is needed. This saves time on-site.
