Powerflushing is essentially a deep, comprehensive clean of your radiators and central heating system, using powerful chemicals to flush out the sludge, rust and any other debris that may have settled over time in your radiators, pipes and boiler.
Powerflushing is recommended for all radiators unless your radiators are especially old; for example, if you’ve moved into a property where the radiators were installed in the 1940s or 50s.
The ultimate aim of a powerflush is to ensure that water can fully circulate your entire heating system, enabling it to work efficiently to heat your home. The process of powerflushing:
Signs that your central heating system may be in need of a powerflush
Powerflushing is key to maintaining a healthy central heating system and avoiding breakdown and there are some clear signs that your system could benefit from this type of deep clean:
To begin the process, a powerful pump, which is attached to the powerflushing machine, is connected to your central heating system.
On a standard central heating system, this means removing the pump and connecting the powerflush hoses to the pump valves. On a combi-boiler system, the powerflushing hoses would be connected to your radiators.
The pump on a powerflushing machine moves fluid through your system 4-5 times faster than the pump on your central heating system, which gives it the power to remove the sludge deposits that typical pressure can’t flush away.
Next, a series of high strength cleansing chemicals are pumped through the heating system to flush out all contaminants. The chemical solutions used typically include an agent to help break down and remove rust and sludge, a descaler to break down limescale and a corrosion inhibitor to stop further rust from occurring.
Completed to a high standard, powerflushing takes several hours from start to finish. The time can vary depending on the size of the central heating system and whether the system is particularly dirty, but essentially, powerflushing your heating system will take a full day.
All of our powerflushes use high quality chemical solutions by Sentinel, a lead international brand with a strong reputation for providing best practice, innovative products for maintaining clean, efficient central heating systems.
Once a powerflush has been completed, central heating filters can further protect your system by reducing the amount of sludge, rust and limescale that build up in your central heating system.
We recommend central heating filters for all systems, and in particular, we recommend the award-winning Magnaclean Adey filter, which we provide and install for £150 on the system that we are powerflushing.
