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.
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.
