A clean system uses less energy to heat your radiators. Better circulation means lower running costs, reduced strain on your boiler, and improved overall efficiency.
Extend System

A powerflush is a deep clean of your central heating system. It removes sludge, rust, and debris that build up inside your pipes, radiators, and boiler over time.
Over time, sludge and corrosion can block your system, causing cold spots, noisy radiators, and reduced heating efficiency. A powerflush helps restore proper circulation and performance.
• Improves heating efficiency and reduces energy bills
• Extends the lifespan of your boiler and system components
• Heats your home faster and more evenly
• Prevents future breakdowns and costly repairs
Common signs include cold patches on radiators, noisy pipes, discoloured water when bleeding radiators, or your boiler frequently breaking down.
Typically every 5–10 years, or whenever you install a new boiler to protect it from existing sludge in the system.
Most powerflushes take between 4 to 8 hours, depending on the size of your heating system and how much build-up there is. Larger or heavily blocked systems may take longer.
