A Power Flush is a cleansing process for your boiler which removes any limescale, sludge, rust and debris that may have accumulated within your central heating system. If these obstructions are left within your system, they can potentially cause blockages or corrosion and ultimately reduce the efficiency of your boiler.
Using a specialised machine; the process involves using a chemical that is circulated through your central heating (pipes and boiler) at a high pressure. The process forces out any potentially inhibiting deposits and thus allows water to flow freely throughout your system. The length of time needed for a Power Flush typically depends on your system's size and condition. Usually, a Power Flush can take up to around 8 hours to perform, however on particularly old or complicated systems, it could take up to 48 hours.
There are plenty of benefits of getting a Power Flush.
These include:
• Enhanced energy-efficiency
• Improved system reliability
• Potentially lower energy bills*
• Reduced likeliness of boiler breakdown
• Could increase system lifespan
• Radiators can warm up quicker
• Better quality of heating and hot water
• Reduced noise from boiler and radiators
Power Flushing is generally required when the system has become heavily compromised. This can be by a number of factors including incorrect installation; typically, when a system has not been thoroughly cleansed before it was installed or from bacterial growth.
If you're planning to get a new boiler installed, the building regulations recommend that a suitable cleanse is carried out before installation. This can vary, from a simple system flush with clean water to a powerful Power Flush. This process ultimately helps to prevent your new system from being contaminated and inhibited by any sludge and debris that was present in your old system.
There are factors that could assist you in determining whether your system needs a Power Flush.
These include:
• Cold spots on your radiators, particularly at the bottom
• The radiators require constant bleeding
• Noisy radiators and boiler
• Radiator leaks
• Frequent breakdowns
• Boiler constantly needs to be restarted
• Central heating takes a long time to heat up
• Some radiators struggle to heat up more than others
