At Fortress Limited, we use a state-of-the-art Fernox power flushing machine along with Fernox chemicals to ensure you receive the best flush of your central heating system.
Not only that, our engineers have attended the Fernox best practice training courses to make sure the machine and chemicals are used to their full potential leaving your heating system in good health and as energy efficient as possible.
Please read our article below for more information on power flushing and get in touch if you require more information.
There are many benefits, such as;
- Prolong the life of your boiler e.g. helps prevent a faulty heat exchanger.
- Improve the energy efficiency of your heating system
- Reduce the risk of rust and corrosion to key components
- Prevent and remove blockages in your system
- Ensure radiators do not suffer from “cold spots”
- Improve the flow rate of water through the system, increasing the speed of heating
A power flush is a process carried out by central heating engineers designed to remove sludgy build-up in the boiler, pipes and radiators that make up your central heating system. A power flushing unit sends water through your central-heating system at high velocity to dislodge any build-up of sludge, rust and other debris.
This helps to improve the efficiency and lifespan of the boiler and central heating system and prevent breakdowns. As with so many plumbing issues, regular maintenance (including power flushing) is the best way to keep your system in shape.
One or more of these symptoms could indicate that your central heating system would benefit from a power flush:
- cold radiators with only a hot strip at the top
- black sludgy water in the heating system (shown by radiator removal or a failed heating pump or valve replacement)
- poor circulation to a system that used to work better
- a magnet attaching to copper pipe-work (signs of iron sludge within)
- an overflowing attic header tank (although this could also be caused by a pump being set at the wrong speed).
No. If there is a broken part in your boiler, or elsewhere in your central-heating system, power flushing will not fix it. Power flushing can improve the efficiency of your system and keep it running effectively but it cannot mend valves that have broken as a result of sludge in the system, for example.
Equally, power flushing is not the solution to pressure loss. That usually indicates a leak in the system – again this may have occurred due to inefficient running, but the power flushing will not solve the problem by itself.
Power flushing works best if it is carried out regularly from when a system is new. If you have an older boiler and system (if it’s 15 years old or more) then power flushing might not work for you. In this case, it’d be more cost-effective to look at replacing the boiler, radiators and maybe some of the pipework, rather than trying to improve a failing system.
Because power flushing pushes water around your central-heating system at high speed, it can increase pressure on any areas of weakness, such as rusting radiators. If there are any underlying weaknesses, it can lead to leaks.
No. It will remove a good proportion of it, but it cannot remove all the sludge in the system. If your system is very old or very-heavily silted up, then power flushing may not be sufficient to remedy the problem.
