Cleaning a central heating system is integral to its health and powerflushing is a popular cleaning method due to the rapid but comprehensive clean it delivers. The benefits of a clean heating system are well-documented:
- more even heat distribution throughout the property
- improved overall energy savings
- lower household bills
- increased system reliability
- extended system life
So how do you know if a system needs a powerflush?
Here are some symptoms to look out for.
- Are certain rooms much colder than others?
- Does it take a long time for system to warm up?
- Are one or more radiators cold at the bottom?
- Do radiators need frequent bleeding?
- Is the boiler noisy?
If you think you have sludge blocking your radiators, get a Gas Safe registered engineer to have a look.
If you need a power flush, the engineer will connect a machine to your system. This will push a powerful, low pressure flow of liquid through your system. This dislodges sludge and rust, removing it from your radiators and boiler.
It can take several hours to flush out your radiator system. It can take even longer if you have a larger system or there’s a lot of sludge.
Your central heating system will contain fresh, clean water after the power flush. The engineer will probably add an inhibitor solution. This liquid chemical will stop sludge building up again.
