Power Flushing in Greater Manchester
Industrial-grade power flushing and central heating deep cleans across Greater Manchester. Magnetic filtration, manual radiator agitation, and a thermal before-and-after report — without replacing your boiler.
Power flushing and central heating system deep cleans across Greater Manchester and North Cheshire for homeowners and landlords in Sale, Altrincham, Chorlton, Cheadle and the wider service area. Cold patches at the bottom of radiators, frequent bleeding, a kettling boiler and lukewarm output are all classic symptoms of magnetite sludge and limescale clogging the system — and a proper power flush often restores full performance without the cost of a new boiler.
Unlike companies that treat a flush as a quick "plug-and-play" upsell, we run a genuine all-day deep clean. Every job starts with a thermal-imaging diagnostic to map cold spots and confirm a flush is actually the right fix rather than radiator or pipe replacement. We then connect an industrial-grade Kamco CF90 (or equivalent) high-velocity pump and drive pulsed water and chemical cleaning agents through every radiator and pipe circuit, reversing direction every few minutes to break up compacted debris.
Crucially, every radiator is manually agitated and reverse-flushed to dislodge stubborn magnetite and iron oxide, with in-line magnetic filtration capturing ferrous debris throughout the process before it can re-enter the system. Once the water runs clear we dose with premium Fernox or Sentinel inhibitor to protect against corrosion for at least five years, then rebalance every radiator for even heat and hand you a thermal before-and-after report showing the improvement. A power flush is included free with every boiler installation. And if a flush won’t fix your cold spots, we’ll tell you honestly rather than hide behind the process. Gas Safe registered, flat-rate pricing.
What's included with every job
The standard kit and approach you get on every power flushing & system deep clean job — no upsells, no surprises mid-job.
Thermal-imaging pre-flush diagnostic
A pre-flush assessment using thermal imaging to identify cold spots, radiator sludge build-up and circulation bottlenecks before a single pipe is disconnected — so we confirm a flush is genuinely the right fix, not a guess.
Industrial-grade high-velocity flush
Industrial Kamco CF90 (or equivalent) pump flushing that delivers pulsed water and chemical cleaning agents through every radiator and pipe circuit, reversing direction regularly to agitate and lift even stubborn, compacted deposits.
Manual radiator agitation
Every single radiator in the property is manually vibrated and reverse-flushed to dislodge compacted magnetite, iron oxide and limescale — the labour-intensive step that separates a genuine deep clean from a quick plug-and-play flush.
In-line magnetic filtration
Magnetic filtration runs throughout the flush to capture and remove ferrous debris as it’s dislodged, before it can simply recirculate and re-settle elsewhere in the system once the pump is disconnected.
Long-life inhibitor dosing
Post-flush chemical inhibition with premium Fernox or Sentinel inhibitor to protect the whole system against future corrosion for a minimum of five years, plus biocide to prevent bacterial growth in the cleaned circuit.
Full system rebalancing
Every radiator lockshield valve is adjusted and each radiator temperature-checked with a digital thermometer to ensure even heat distribution across all rooms once the flush is complete, so warmth is balanced not concentrated.
Thermal before-and-after report
A thermal-imaging before-and-after comparison handed to you at the end, showing previously blocked, cold radiators now flowing and heating evenly — clear visual proof of the difference the flush has made.
From enquiry to sign-off
A simple, predictable process from your first message through to the walk-round at the end.
- 1
Pre-inspection
Our engineer surveys the heating system, measures the extent of the cold spots with thermal imaging and confirms whether a power flush is the right fix — versus replacing radiators or sections of pipework.
- 2
System connection
We connect the power flushing rig to your central heating circuit, typically via the pump connections or a radiator valve, isolating the rest of the system so the cleaning agents are driven exactly where they’re needed.
- 3
Deep clean cycle
Heated water mixed with specialist chemical cleaners is pumped through every radiator and pipe run at high velocity, reversing direction every few minutes, while each radiator is manually agitated to break up stubborn debris.
- 4
Final flush, dose & rebalance
The system is flushed until it runs clear, dosed with long-life inhibitor, then every radiator is temperature-checked and balanced for even output, with a thermal before-and-after report provided at handover.
Up to 10 radiators £495 flat; 11–15 radiators £595; 16+ on survey. Includes chemicals, magnetic filtration and inhibitor. Free with every boiler installation.
