Power Flushing
What is Power Flushing
A power flush is a deep clean of your heating system designed to remove sludge, debris and blockages from radiators and pipework. Over time, heating systems naturally build up corrosion and magnetite, which reduces efficiency, causes cold spots and puts strain on boilers and pumps. A professional power flush restores proper circulation, improves performance and helps protect your heating system from future issues.
Signs You May Need a Power Flush
-
Radiators cold at the bottom or slow to heat
-
Noisy boiler or banging pipes
-
Dirty or discoloured heating water
-
Frequent pump or valve failures
-
Poor circulation or uneven heating
-
Boiler cutting out or showing fault codes
-
Heating system older than 10–15 years
If you’re experiencing any of these, a power flush can often resolve the problem without replacing major components.

Benefits of a Power Flush
-
Improved efficiency: Better circulation and faster heating.
-
Lower running costs: Reduced strain on the boiler and pump.
-
Longer system lifespan: Helps protect boilers, pumps and valves.
-
Warmer radiators: Removes cold spots and blockages.
-
Cleaner system water: Reduces corrosion and future sludge build‑up.
-
Better reliability: Helps prevent breakdowns and fault codes.
Our Power Flushing Process
We use specialist equipment and chemicals to safely clean your heating system:
-
Connect power flush machine to the system
-
Add cleaning chemicals to break down sludge
-
Reverse‑flow agitation to dislodge debris
-
Flush each radiator individually
-
Remove sludge, rust and magnetite
-
Add inhibitor to protect the system
-
Test circulation and radiator performance
All work is carried out safely, cleanly and to a high standard.
What We Flush
-
Radiators
-
Pipework
-
Heating circuits
-
Boiler heat exchangers (where suitable)
-
Pumps and valves
-
Hot water coils (depending on system type)
We’ll assess your system first and explain exactly what’s needed.
Do You Need a Power Flush or a Chemical Flush?
Not every system needs a full power flush. In some cases, a chemical flush or filter installation is more suitable.
We’ll advise honestly based on:
-
System age
-
Radiator condition
-
Boiler type
-
Water quality
-
Circulation performance
You’ll never be sold a flush you don’t need.
Aftercare & Protection
Once the flush is complete, we can install:
-
Magnetic filters
-
System filters
-
Inhibitors
-
Scale reducers
-
Water testing kits
These help keep your system clean and efficient long‑term.
