Power Flushing
What is Power Flushing?
Power Flushing, Jet Flushing and Hard Flushing... are all expressions used (in the heating trade over many years) to denote the process by which heating systems are forcibly cleansed using water at high velocity, but low pressure, so that no physical damage is caused to the system.
The objective is to restore systems with circulation and boiler noise problems (caused by sludge and corrosion deposits) to optimum operation. Power flushing removes these deposits and the problems that they cause.
Please Note when enquiring about a power flush we need to know the following:
- How many radiators?
- Type and make of boiler. This is so we know what chemical to use as some of the boilers have aluminium heat exchangers.
- Symptoms that are present on the heating system.
System Effects and Flushing Recommendations
Power flushing is the most effective method of cleansing a central heating system. A power flush is recommended as the optimum method of restoring system efficiency, particularly on an existing system. A power flush combined with an effective cleanser and administered correctly will remove up to 95% of system sludge and scale.
The benefits of system flushing are:
- Improved system efficiency
- Maintains boiler efficiency (1mm thickness of scale / sediment will reduce efficiency by approx. 10%)
- Reduced fuel costs (boilers will consume up to 25% more fuel if system is unclean)
- Reduced greenhouse gas emissions
- Reduced maintenance costs
- Reduced potential for boiler noise
- Extends system life
