| | | PowerFlushing Courses at UK One Training - Birmingham |  | | UK One Training supports the BENCHMARK initiative. | | Introduced in October 1999 Benchmark was launched to improve the standards of installation and commissioning of central heating systems in the UK and to encourage the regular servicing of all central heating systems to ensure safety and efficiency. UK One actively promote the Fernox range of protection and restoration products as these help meet the recommendations of the code of practice, and facilitates both pre-commission and existing system cleansing in accordance with BS7593:1992 “A code of practice for treatment of water in domestic hot water and central heating systems”.

| Fuel wastage | Without treatment, corrosion debris will accumulate in the boiler causing increasing limescale deposits, reduced heat transfer and up to a third of a fuel bill going to complete waste. | | Boiler noise | This increases in frequency and intensity as deposits of sludge and scale build up in an unprotected boiler. |
| Cold spots | The familiar cool low central area of a radiator indicates a build-up of black sludge sediment that restricts flow and reduces heat. | | Frequent venting | When the top of a radiator is cold during operation, either air or hydrogen is to blame. Hydrogen gas builds up as a by-product of electrolytic corrosion and is flammable (due caution is required). | | Pump seizure and failure | The abrasive and magnetic properties of black oxide sludge increase shaft and bearing wear in pumps causing them to stick or fail. |
The cleaning and treating of central heating systems | | All new systems should be pre-commission cleansed in accordance with BS:7593 and Benchmark. This ensures flux residues, excess jointing compounds, mineral oil and other contaminants that can be found in the system following installation, and that can effect the performance of the system or cause component failure, are removed. | It is important when installing new boilers into old systems that all sludge is first removed from the system or this could accumulate in the new boiler and lead to premature failure. Additionally, in hard water areas existing systems will have accumulated limescale together with corrosion deposits in the heat exchanger, which could easily have reduced the boiler efficiency by over 5%. |
