Central Heating Power Flush in Exeter

Cold radiators, cold spots or a noisy boiler? A power flush clears the sludge out of your central heating across Exeter and Devon — cleaner system, warmer home, longer-lasting boiler.

Power flushing

Clear The Sludge, Warm The Home

Over the years, central heating systems build up sludge and rust inside the pipes and radiators — and that's usually what's behind cold spots, radiators that won't warm up and a boiler that bangs or gurgles.

A power flush pushes a cleaning solution through the whole system at high flow to shift all that gunk out. SWW carries out power flushes across Exeter and Devon, leaving your heating running cleaner, warming up faster and costing less to run — and it takes real strain off your boiler. We'll also add inhibitor to help keep the system clean going forward. It's often well worth doing before fitting a new boiler, too, so you're not pumping fresh heat through a dirty system.

Signs you need one

Does Your System Need Flushing?

If any of these sound familiar, a power flush will likely help.

Cold Spots On Radiators

Radiators warm at the top but cold at the bottom is the classic sign of sludge sitting inside.

Some Radiators Cold

If certain rads never really get going while others do, the flow's being blocked by build-up.

Slow To Warm Up

A system that takes an age to heat the house is often clogged and working harder than it should.

Noisy Boiler Or Pipes

Banging, gurgling or kettling noises are often down to sludge and trapped debris.

Dirty Water When Bled

Black or brown water when you bleed a radiator is rust and sludge — exactly what a flush removes.

Before A New Boiler

Flushing before a new boiler protects your investment and is sometimes needed for the warranty.

Common questions

Central Heating Power Flush in Exeter FAQs

What is a power flush?

It's a deep clean of your central heating — a machine pushes cleaning chemicals and water through the system at high flow to clear out sludge, rust and debris that build up over time.

How do I know if I need one?

Cold spots on radiators, some rads not heating, slow warm-ups, noisy pipes or a banging boiler, or dirty water when you bleed a radiator — all signs sludge has built up.

How long does a power flush take?

Most take the best part of a day, depending on the size of the system and how much build-up there is. We'll give you a timescale with your quote.

Will it help my heating bills?

Usually yes — a clean system heats up faster and runs more efficiently, so you're not paying to push heat through a clogged system.
