Power Flushing
— About This Service
Power Flushing Done Right
Cosy, even heating throughout your home and a longer-lasting boiler: our power flushing service clears black iron oxide, sludge and limescale that restrict flow so radiators heat evenly and pumps run freely. Serving New Milton, Christchurch and Lymington, we restore system performance, reduce cold spots and extend component life. Work is carried out by Gas Safe registered engineers with Vaillant and Glow-worm accreditation, and includes a before-and-after performance check plus written report.
— Our Process
How It Works
System Survey
We inspect the system, identify cold spots and measure flow to decide where to connect the flushing machine and which chemicals/inhibitors to use.
Power Flush
Using a high-flow flushing machine and industry-grade chemicals we dislodge and extract sludge, iron oxide and debris, flushing until the return runs clean.
Final Check & Report
We fit or top up corrosion inhibitor, balance radiators, re-test flow and provide a written before-and-after report with recommendations for ongoing care.

Why Choose us for Power Flushing?
Even, faster heating
Clearing deposits restores water flow so radiators heat evenly and rooms reach temperature quicker — no more cold spots.
Longer boiler & pump life
Removing abrasive sludge reduces wear on the pump and heat exchanger, lowering the risk of breakdowns and extending component life.
Qualified, local engineers
Gas Safe registered and Vaillant/Glow-worm accredited engineers from New Milton deliver safe, documented work backed by 20+ years' experience.
What a power flush does
Central heating systems gather black iron oxide and limescale that settle in radiators and pipework. A professional power flush forces cleaning fluid through the system at high flow, dislodging deposits and extracting them to leave the loop free-flowing. The result is improved heat distribution, fewer hot/cold spots and reduced strain on the boiler and pump.

— FAQ
Frequently Asked Questions
Frequency depends on system condition and age. A healthy system with regular inhibitor checks may only need flushing after many years, while older systems or those with recurring cold spots can benefit sooner. We inspect the system and recommend timing based on flow tests and a visual assessment.
