Why power flush?
Why is power flushing so highly recommended?
Over time, sludge, rust and limescale build up inside every central heating system.
Left alone, that thick black sludge cuts the flow of heat and hot water, blocks pipes and valves, and can do lasting damage to your boiler and radiators. A power flush clears it out and restores full circulation, so every room heats evenly and your boiler and pump stop working overtime.
It can help lower your energy bills, reduce wear on your boiler and extend the life of your whole heating system, which is why it's recommended at regular intervals to keep your system in the best condition.

On the day
What happens during a power flush.
It’s far less disruptive than most people expect.
We need access to your radiators, pump and boiler (and the loft if your tanks are up there), and most homes are done in a day.
- 01
We connect the power flushing machine
Your engineer attaches the machine to a single point in your system, usually the pump, and circulates clean water and cleansing chemicals.
- 02
Each radiator flushed individually
Where it’s needed, radiators are flushed one by one to shift stubborn sludge and blockages.
- 03
Flushed until the water runs clear
The loosened sludge is drained away safely and cleanly, and we keep going until the water runs clear.
- 04
Scale and corrosion inhibitor added
Your system is refilled with clean water and an inhibitor that slows future corrosion and build-up.
- 05
Rebalanced, radiator by radiator
We balance the system so heat reaches every room evenly and your boiler isn’t working harder than it needs to.
6–12 hours in an average home, longer with microbore piping
3-year guarantee on every power flush, or 5 years with a MagnaClean filter
