Power flushing is a process of cleaning a new or existing central heating system. We fill the system with a cleaning agent and using our power flushing machines we clean the system of any sludge and debris which could be harmful to your system.
A system containing sludge could be causing your energy bills to rise. This is due to poor circulation, meaning longer running times to circulate the heat around the house correctly.
Inhibiting the system after installation for carrying out maintenance after re filling the central system is highly important to protect the system from future corrosion.
What is meant by corrosion in a central heating system?
From the time of installation and commissioning a central heating system will, potentially, start to corrode. This is because water in the system will start to react with the steel in the radiators. To reduce the rate of corrosion, a plumber will flush out a newly installed system to remove any debris or substances likely to increase the rate or risk of corrosion.
The most common symptom of corrosion within a central heating system is sludge, a black, mud like, deposit resulting from the reaction between the water in your system and the steel in the radiators.
The sludge can build up over a period of time in an untreated central heating system, and cause:
- Damage to the boiler.
- Damage to radiators by causing pin holing and leaks.
- Damage to the pump.
- Damage to the thermostatic radiator valves
- Blocked pipework
- Damage to zone valves causing them to stick open
- Blocked and damaged hot water heat exchanger on a combination boiler
The metal components within your central heating system particularly the radiators are constantly reacting with the water running through them and needs treatment to avoid excess rust, sludge and scale blocking up your central heating system.
