Restore Your Heating System’s Power & Efficiency with Power Flushing and System Cleans
Professional power flushing and system cleans to remove sludge, rust, and cold spots — improving warmth, performance, and boiler lifespan.
Power Flushing and System Cleans across Leeds and Surrounding Areas
Over time, sludge, rust, and scale can build up in radiators and piping, restricting flow and reducing boiler efficiency. A professional power flush or system clean removes these deposits, restores circulation, and helps your heating run more reliably and cost-effectively.

What we offer
- Full system power flushing: Using purpose built equipment to circulate cleansing chemistry through the boiler, pipework, and radiators to dislodge sludge and debris.
- Targeted radiator cleans: Focused flushing on specific radiators if blockages are localised, with radiator-by-radiator balancing after cleaning.
- Magnetic filtration and protection: Fitting or upgrading magnetic filters to capture debris and dosing the system with protective inhibitors to prevent future corrosion.
- Inhibitor dosing and protection: Post-clean dosing to protect the system and maintain cleanliness for longer.
- Boiler and pump protection checks: Pressure testing, leak checks, and pump integrity assessment after cleans.
- System commissioning and balancing: Re-pressurisation, efficient bleed and air removal, radiator balancing, and temperature checks to ensure even heat distribution.
- Compliance and reporting: Pre- and post-clean reports, documentation for warranties, and adherence to current guidelines and manufacturer instructions.

Our Process
- Free survey and assessment: We inspect the boiler, pipes, and radiators, confirm access, and discuss goals and budget.
- Plan and protection: Prepare the site with protective measures for floors and furnishings; isolate sections of the system as required.
- Flush and cleanse: Attach the power flushing machine, circulate cleansing agents, and remove sludge through controlled drainage; use filtration to capture debris.
- Inhibitor dosing and protection: Refill with clean water, dose corrosion inhibitors, and test pressures.
- Commissioning and balancing: Repressurise the system, bleed radiators, and balance heat distribution for even comfort.
- Handover and maintenance: Provide operation tips, maintenance guidance, and warranty details.

Benefits you can expect
- Improved boiler efficiency and lower running costs due to better heat transfer and reduced flow resistance.
- More even heat: Fewer cold spots and faster heat-up times.
- Longer system life: Reduced corrosion and sludge-related wear.
- Quieter operation: Fewer banging noises and pump strain.
- Cleaner system: Less likelihood of future blockages and fewer radiator bleed issues.

Signs your system may need a clean
- Cold spots in radiators or poor heat distribution
- Radiators requiring frequent bleeding
- Boiler short-cycling, loss of pressure, or knocking noises
- Visible sludge in radiator fins or towel rails
- Increased fuel bills without a change in usage
