Why might powerflushing be required?
Rust occurs in all Central Heating systems producing a black sludge (iron oxide) and, in hard water areas, limescale builds up in combination boilers just like in your kettle causing the following problems:
- Radiators cold at bottom due to black sludge.
- Radiators cold all over due to blocked valves and pipework.
- Radiators cold at top and need bleeding due to gases, a by-product due to rusting.
- Boiler cutting out and no circulation due to blocked pump.
- Little or no hot water due to blocked pipes and heat exchangers.
- Irritating boiler noise from sludge or limescale build up.
What is powerflushing?
Powerflushing is a rapid movement of water through the system, using a high-powered pump, which is aided, by the use of cleaning chemicals to remove deposits.
It is the only effective way to remove debris and sludge from the central heating system, expelling the dirty water to the drain and replacing with clean water from the mains supply, which can be done in either direction of flow.
After flushing the radiators the system water will be tested with a TDS meter and must be within 10% of the reading gained from the mains water supply. The clean system is then ready for treatment with a corrosion inhibitor.
