A power flush is a procedure that is designed to clean your central heating system, by removing any sludge, rust or debris that may have built up over time.
80% of boiler and central heating problems are caused by sludge buildup in the system, so power flushing can help to prevent boiler breakdowns and related maintenance costs.
WARNING: You should never attempt to power flush your system yourself, as this could cause considerable damage to your central heating apparatus.
Your central heating system may require a power flush if you are experiencing some or all of the following problems:
It is also recommended that you power flush your system before you have a new boiler fitted, to make sure that all debris is removed from the system.
WARNING: Many boiler warranties state that your policy will be void unless the system is power flushed before the boiler is installed, as any lingering rust or particles can damage the boiler and block the filters.
Power flushing is a fairly simple procedure:
IMPORTANT: Power flushing may not be suitable for microbore systems or open vented systems. In these cases ‘powder flushing’ is usually more effective for removing debris.
On average, a routine power flushing service takes between 4 and 6 hours, however, this can differ depending on the size of your central heating system and the amount of rust or sludge present.
Again, this will depend on the size of your central heating system and the amount of work required. Most companies quote a starting price of £350, but it is not unheard of for power flushing to cost more than £1,200. You should be wary of insurance companies that offer a power flush service attached to an insurance policy, as they may charge a lot more for the service than an engineer would.
You should always use a qualified heating engineer or heating company to carry out a power flush. When choosing an engineer, check that they have insurance that will cover any damages that may occur if any problems arise during the service.
You can find further information on power flushing at The Power Flush Association website, or ask a qualified engineer during your annual boiler service.
