Central Heating Powerflush in Hanwell

The Brief

A family in Hanwell had been struggling with their central heating for some time. Several radiators had persistent cold spots, the system took an age to warm up, and a couple of radiators were cold at the bottom no matter how high the thermostat went. These are the classic signs of sludge building up inside the system, so the homeowners called us in to get the heating working properly again before the cold weather set in.

What We Did

Our work included:

• Assessed the system: We checked each radiator, confirmed the cold spots and slow heating were caused by sludge and debris, and gave a clear, fixed price for the powerflush before starting.
• Connected the powerflush equipment: Our specialist powerflushing unit was connected to the system, ready to circulate water and cleaning chemicals at high velocity.
• Cleared the sludge: We flushed every radiator and the full circuit, dislodging years of rust, dirt and debris and flushing it all out so water could circulate freely again.
• Treated each radiator: Radiators with the worst cold spots were worked individually to break down stubborn deposits and restore full flow across the surface.
• Added a corrosion inhibitor: Once the system ran clean, we added an inhibitor to protect against future sludge and rust, helping keep the system clean for years to come.
• Tested the system: We balanced the radiators and ran the heating to confirm even, fast heating across the whole home, with no remaining cold spots.

The Result

Even, reliable heat restored throughout the home. The radiators now warm up quickly and evenly, with no cold spots, and the whole system heats far faster than before. Clearing the sludge has also taken the strain off the boiler and pump, protecting them from premature wear and helping the system run more efficiently. The homeowners were delighted to have warm, responsive heating again.

Job Duration: Completed in a single visit, with the system fully flushed, treated and tested the same day.
