If sludge is present within the system, we can remove it. We use a high-pressure machine which forces water through the system to flush out the sludge and debris. This will unblock any pipes and radiators. If only one radiator is suffering from sludge build up, we may only need to flush one part of the system, but more common than not the whole system will have sludge build up. This process requires water to be pushed through until it runs clear, and this may take some time. Once the power flush is complete, we will then fit a magnetic system filter which will collect any sludge in the system. This filter is required to be cleaned out each year and will protect your boiler and central heating system from any more sludge build up.
Although sludge build up in central heating systems can be resolved, prevention is always a better method. When we install new boilers, we fit a magnetic system filter as standard. It is a requirement from most boiler manufacturers now. We will also power flush the system when installing a new boiler, so the water is nice and clean, so it won’t block up the new boiler.
There are many different magnetic system filters on the market. Some boiler manufacturers have their own filters which they recommend fitting when installing a boiler.
