With time central heating systems corrode internally producing black iron oxide sludge deposits in your radiators. These particles stick to all surfaces and cause circulation and flow problems to your heating system. If you have any of the following problems:
Radiators that do not heat up at all
Some radiators are hot at the top and cold at the bottom
Radiators that need regular bleeding of air
Noisy boiler or pump
Regular pump failures
Central heating takes a long time to heat up
Reduced hot water temperature
Visible evidence of sludge or rust in the system
…then your heating system might need to be power flushed.
Benefits of a power flush:
Cures flow and circulation problems and improves the efficiency of your heating system
Restores heat output to radiators
Helps you save up to 25% on your fuel bills
Reduces noise of boiler operation due to lime scale removal
What is power flushing? Power flushing is the most efficient and effective method of cleansing a central heating system. The principle is to create a powerful fresh water flow under controlled conditions to remove debris from the system and restore your heating system to its optimum operation. Having your system professionally power flushed will not only help prolong the life of your heating system but will also increase its efficiency. This can save a dramatic amount on the quantity of energy you use leading to cost savings in your fuel bills and smaller impact on the environment.
How does it work? The power flushing pump is connected up to your heating circuit. From there it circulates a chemical around the pipes, radiators and boiler breaking down any sludge it comes into contact with. Once the corrosion or deposits of sludge have been loosened, clean water is forced through the heating circuit, pushing the contaminated water out through a waste valve. The radiators are then individually flushed, without disconnecting them from the system.
We recommend to power flush a heating system prior to installing a new boiler to an existing system to prevent possible problems in the future. Many systems, even those as new as 6 months old are found to contain corrosion and sludge and it is now specified in Part L of the Building Regulations that all central heating systems must be thoroughly flushed prior to the installation of a new boiler. It is now common for all boiler manufacturers to insist that systems must be flushed prior to commissioning a new boiler or the warranty will be invalidated.
Prolong the benefits of power flushing with a Fernox TF1 or MagnaClean
After the power flush we recommend to install either a Fernox TF1 or MagnaClean magnetic filter to your central heating system. When combined with a power flush, these filters give you added peace of mind that any future corrosion which occurs within your system will be filtered out before it reaches your boiler.
Both the Fernox TF1 and MagnaClean filters contains a powerful magnet which attracts virtually 100% of suspended black iron oxide deposits (sludge) and will ensure that your boiler operates at peak efficiency.
You can further increase the performance of your magnetic central heating filter by using an inhibitor to reduce the formation of iron oxide in your system.
