Ace Gas NW Ltd provides professional powerflushing services across Wigan and the North West, removing sludge and debris to restore heating efficiency and extend your system's lifespan.
Specialist equipment for thorough system cleaning
Gas Safe registered engineers with over 40 years experience
Improves efficiency and reduces energy bills
Often essential before new boiler installation



Over time, central heating systems accumulate rust, sludge, and debris that circulate through your pipes and radiators. This contamination reduces heating efficiency, causes cold spots on radiators, creates banging or gurgling noises, and forces your boiler to work harder, increasing energy bills and wear. In severe cases, sludge buildup can damage your boiler beyond repair. Powerflushing is often essential before installing a new boiler to protect your investment and maintain warranty validity.
Ace Gas NW Ltd uses professional powerflushing equipment to thoroughly clean your entire heating system across Wigan and throughout the North West. Our Gas Safe registered engineers have over 40 years of combined experience identifying when powerflushing is necessary and carrying out the procedure properly. As members of the Wigan Good Trader Scheme with 100+ five-star reviews on both Google and Checkatrade, we provide honest advice about whether your system genuinely needs powerflushing – we won't recommend it unless it's truly beneficial. Our comprehensive service restores heating performance, extends system life, and ensures new boilers aren't compromised by contaminated pipework.
Our engineer assesses your heating system's condition, then connects professional powerflushing equipment to circulate cleaning agents at high velocity throughout your entire system.
We flush each radiator individually whilst powerful chemicals break down sludge and debris, reversing flow direction repeatedly until the water runs completely clear from every outlet.
Once thoroughly cleaned, we add corrosion inhibitor to protect your system long-term, balance all radiators, and test the entire system to ensure optimal heat distribution and efficiency.

"A proper powerflush takes time and can't be rushed. We're not just shifting sludge around, we're removing it completely. When customers see the black water coming out of their system, they understand why their heating wasn't working properly. It's satisfying work that makes a real difference."

How do I know if my heating system needs powerflushing?
Common signs include cold spots on radiators (especially at the bottom), noisy boiler or pipes, radiators taking longer to heat up, frequent boiler breakdowns, or cloudy water when bleeding radiators. If you're installing a new boiler, most manufacturers require a system flush to validate warranties. Our engineer can assess your system and provide honest advice.

Will powerflushing damage my heating system?
No, powerflushing is safe when carried out properly by qualified engineers using professional equipment. The process actually protects your system by removing corrosive sludge that causes long-term damage. We use appropriate chemicals and pressures for your specific system type.

How often should a heating system be powerflushed?
Most systems don't require regular powerflushing if properly maintained with corrosion inhibitor. However, powerflushing is recommended if you're experiencing heating problems, before installing a new boiler, or if your system is over 10 years old and has never been cleaned. Annual inhibitor checks help prevent excessive contamination.

What's the difference between powerflushing and a chemical flush?
Powerflushing uses high-velocity water flow with specialist equipment to physically dislodge and remove sludge throughout the entire system. A chemical flush simply adds cleaning chemicals to the system without the powerful flushing action. Powerflushing is far more effective for heavily contaminated systems, whilst chemical flushes suit newer, lightly contaminated installations.
