SLUDGE COSTS YOU MONEY EVERY MONTH YOU LEAVE IT

Magnetite sludge builds up inside every central heating system over the years — black, gritty particles from internal corrosion that settle at the bottom of radiators and restrict flow. By the time you notice cold patches at the bottom of radiators or a noisy boiler, sludge has probably been building for years. Your boiler is working harder than it needs to, your gas bill is higher than it should be, and your boiler’s lifespan is being shortened.

A professional power flush blasts the system with cleaning chemicals and high-flow water to break up and remove the sludge, then refills with inhibitor to prevent it returning. Combined with a magnetic filter (which we fit as standard), a properly flushed system can run trouble-free for another 10–15 years.

SIGNS YOUR SYSTEM NEEDS A POWER FLUSH

Any of these usually mean magnetite sludge has built up significantly

COLD AT RADIATOR BOTTOMS

Top of radiator hot, bottom cold to touch — sludge has settled in the bottom and is restricting flow.

NOISY BOILER

Banging, kettling, whistling sounds from the boiler — sludge restricting flow through the heat exchanger.

SLOW WARM-UP

Rooms take much longer to reach temperature than they used to — sludge is restricting circulation.

INCONSISTENT HEAT

Some radiators piping hot, others lukewarm — uneven sludge distribution affecting flow.

HIGHER GAS BILLS

Bills creeping up year-on-year for no obvious reason — sludged system making the boiler work harder.

BOILER LOCKOUTS

Boiler shutting itself down due to overheating — sludge preventing heat exchanger from rejecting heat.

ECOGAS'S POWER FLUSH PROCESS

PROFESSIONAL FLUSH

Industrial-grade power flushing equipment connected directly to the system. Chemical cleaner circulated for full system reach. High-flow water removes all loosened sludge.

PROTECTION AGAINST RETURN

Refilled with manufacturer-approved corrosion inhibitor. Magnetic filter fitted as standard if not already present. System runs cleaner and stays cleaner for years.

WHAT PERTH SAYS AFTER A POWER FLUSH

Adam K. — Perth

Five radiators were cold at the bottom. EcoGas did a full power flush, the water that came out was jet black. Radiators are evenly hot now, boiler runs quieter, gas bill is noticeably lower. Outstanding.

Beatrice L. — Perth

Boiler had been making banging noises for months. The technician explained sludge was the cause — heat exchanger couldn't reject heat properly. Power flushed, fitted a magnetic filter, banging gone. Should have done it ages ago.

Calvin R. — Perth

Mentioned at our annual service that one radiator was sluggish. EcoGas didn't pressure us into a flush — said it was worth monitoring. Six months later three radiators were cold-bottomed. Came back, flushed properly, no upsell. Honest people.

Diana H. — Perth

Inherited a 30-year-old system when we moved in. EcoGas power flushed before commissioning a new boiler — protected the warranty and the boiler itself. The amount of black sludge that came out was unbelievable.

POWER FLUSHING FAQS

HOW DO I KNOW IF I REALLY NEED A POWER FLUSH?
The classic signs are: radiators cold at the bottom but hot at the top, banging noises from the boiler, gas bills creeping up year-on-year, slow warm-up times, and visible black sludge in the magnetic filter (if you have one). We diagnose with thermal imaging and a magnetic filter check — we’ll tell you honestly if a flush is the right answer or if individual radiator cleaning would do the job.
A standard 3–4 bed home takes 4–6 hours. Larger homes (5+ bedrooms or unusual layouts) can take 6–8 hours. We start early in the day and aim to be finished by late afternoon, so you’re not without heating overnight. The system runs as normal as soon as we leave.
Properly done, no — and that’s the key qualification. Cheap or rushed power flushes have been known to disturb old leaking pipework. Our process is thorough but controlled — we monitor pressure throughout and address any weak joints found during the flush. We’ll always survey the system first and flag any concerns before quoting.
Yes, usually noticeably. A clean system circulates faster, the boiler reaches target temperature sooner, radiators warm more evenly, and the whole system runs at lower temperatures more efficiently. Typical savings are 10–20% on heating bills in the first year after a flush — pay-back is usually 2–3 years on a £420 flush.
Yes — every power flush includes fitting a magnetic filter at no extra cost. Magnetic filters capture sludge particles before they settle in radiators, extending the benefits of the flush by years. We use Adey, Fernox or Spirotech filters depending on the system.
Yes, in most cases — and it’s a manufacturer requirement for most warranties. Fitting a new boiler to a sludged system would void the warranty and damage the new heat exchanger within months. We always recommend (and usually require) a power flush as part of any new boiler install — usually quoted as one combined job.
