Local Power Flushing
Over time, central heating systems become clogged with rust, dirt and debris, forming a sludge called magnetite. A power flush cleans all this sludge from your heating system by pushing a powerful cleanser through it. This dislodges the sludge and removes it from your radiators and boiler, ensuring they can function properly.
Regularly power flushing your central heating system helps prevent radiator blockages and rust, protects your boiler and key components like pumps and motorised valves, and ensures your system operates more efficiently.

How Often Should You Power Flush Your Heating System?
As a general guideline, it’s recommended to power flush your heating system every 5 years to keep it in optimal condition.
The frequency of power flushing your central heating system depends on several factors, including the material of your radiators, the age and type of your boiler, and the water hardness.
If your system includes high-quality materials, you may be able to extend it to 8–10 years while still maintaining functionality. For older boilers, more frequent power flushing may be necessary to prevent issues and maintain efficiency.
We recommend a power flush before winter, ideally at the start of Autumn, so your heating isn’t disturbed when you need it, and you can rely on it working for the colder months.
How Long Does a Power Flush Take?
The time taken to complete a power flush depends on the time of your last flush, the amount of dirt and sludge in your system and the size of your property. For a relatively clean and small system, the process may take just a few hours. However, larger systems with significant buildup could take many hours or even an entire day to complete.
Regular power flushing not only protects your heating system from issues but also makes future maintenance quicker and more straightforward for plumbers. Keeping your system well-maintained ensures a more efficient and hassle-free service when it’s time for a flush.
How Do I Know if My Radiators Need Power Flushing?
Knowing when you need a radiator power flush can prevent bigger problems down the line. Look out for these key signs:
- Cold spots, especially in the centre: Feel your radiators when the heating is on. If the centre or bottom feels colder than the top, sludge may have built up and is blocking heat. If the top of a radiator is cold, it’s more likely due to trapped air. Try bleeding the radiator, as a power flush won’t resolve this issue.
- Uneven heating in rooms: If a particular room isn’t warming up as it used to, your heating system may be struggling due to blockages.
- Brown or grey water when bleeding radiators: The colour of the water is another clue. Brown or grey water suggests a power flush is needed soon, especially if it contains small particles of dirt.
- Noises from your boiler: Rumbling or knocking sounds might indicate an issue with the boiler or the system as a whole. If this persists after servicing your boiler, sludge in the system could be the culprit.
