EXPERT ADVICE ON POWERFLUSHING A HEATING SYSTEM
Are you experiencing cold radiators, poor circulation, or black sludgy water in your heating system? If so, your central heating system might benefit from a power flush. In this blog, we’ll delve into what a power flush is, the process involved, when it’s needed, and the benefits it brings to your heating system.
What's a Power Flush?
A power flush is a crucial process carried out by qualified central heating engineers to combat sludgy build-up in your central heating system. Over time, debris, rust, and sludge can accumulate in your boiler, pipes, and radiators, causing reduced efficiency and potential breakdowns. A power flushing unit is used to send water through your system at high velocity, effectively dislodging and removing the unwanted build-up.
The Power Flushing Process
When a power flush is carried out, a powerful machine known as a ‘pumping station’ is utilized to remove the dirty water and sludge while introducing clean water into the system. Before starting the flushing process, the engineer might add a chemical to break down sludge effectively.
The power flushing process involves several stages and can take anywhere from several hours to a whole day, depending on the size and condition of the system. The engineer begins by flushing the entire system in both directions for around 90 minutes. Then, they focus on troublesome sections until they run clean. Heavily contaminated radiators may require special attention, and an ‘agitator’ can be used to release internal sludge build-ups.
After clearing out the system, a chemical neutralizer is added, and the system is washed through. The engineer will also check the system’s pH balance to ensure it is not too acidic, as excessive acidity can lead to internal corrosion. Finally, a dose of ‘inhibitor’ fluid is added to the system, preventing corrosion and reducing the likelihood of future sludge build-up.
When Does Your Heating System Need a Powerflush?
Several symptoms can indicate the need for a power flush:
- Cold radiators with only a hot strip at the top.
- Black sludgy water in the heating system.
- Poor circulation in the system.
- A magnet sticking to copper pipe-work (a sign of iron sludge).
- An overflowing attic header tank.
If you’re considering installing a new boiler but have an old central heating system with old-style radiators, a powerflush might be recommended. Your boiler engineer can perform visual and chemical checks to determine whether a full power flush is necessary or if a ‘dynamic flush’ using clean mains pressure water would suffice. For every new boiler installation, thorough flushing of the system is required, though not necessarily a power flush.
Who Should Perform a Powerflush?
A power flush should only be carried out by a suitably qualified central heating engineer. This is not a DIY task, especially if your engineer needs to examine other faults in the central heating system or open up your boiler.
While power flushing is an effective method to improve system efficiency and prevent issues, it may not solve all problems. If there is a broken part in your boiler or central heating system, a power flush will not fix it. Power flushing also cannot resolve issues like pressure loss, which may indicate a leak in the system.
Additionally, if your system is very old or heavily silted up, power flushing might not be sufficient to fully remedy the problem. In such cases, considering a boiler and radiator replacement along with some pipework might be a more cost-effective solution.
