Power Flushing

What is Power Flushing? - Power flushing uses an external pump that is connected to your central heating system, this pump is capable of removing the debris buildup that is stopping your system from running efficiently.

Why do I need to power flush my system? - During the course of normal operation, your central heating system will corrode and cause a build up of sludge in the system. This sludge can stop the flow of heating water reaching your radiators, it may also lead to a costly break down of your boiler. It is also a requirement to flush any existing central heating system when a new boiler is being installed, power flushing is the most effective way of flushing a system. Failure to do this may invalidate any boiler warranty.

How does power flushing work? - Power flushing uses a combination of chemicals, magnets and pressure to clean all the internal components of your central heating system restoring efficiency.

How long will it take? - Power flushing is not a ten minute job, some companies suggest power flushing can be done in as little as 2 hours, in our experience it will take 4-5 hours based on a standard 7-8 radiator system to effectively clean and will require an initial vist to assess your system and add chemicals.

Power flushing does not require any qualifications, there are no restrictions for DIY flushing, however there are risks involved and a full assessment should be carried out by an experienced heating engineer prior to flushing. An open vented system should be approached differently to a sealed system, is there a suitable water supply available? Are the radiator valves in good condition? Is there any signs of corrosion on the radiators? Power flushing involves using a large volume of water, if obvious weaknesses have been overlooked, due to inexperience, severe water damage may occur.
