Power Flushing for Central Heating Systems

Over time, central heating systems build up sludge, rust, debris and magnetite. That contamination restricts circulation, reduces efficiency and leads to costly breakdowns. Our professional power flush clears it out, restores proper flow and protects your boiler. Fixed pricing from £495 including VAT.

Restore your heating to its best

A heating system clogged with sludge and rust has to work much harder to warm your home. Radiators take longer to heat, some never get warm at all, and your boiler is put under constant strain. Left alone, it quietly pushes up your energy bills and shortens the life of your boiler.

A power flush uses specialist equipment and cleansing chemicals to clear that build up out of your radiators and pipework, then refills the system with fresh water and a corrosion inhibitor to keep it clean. The result is faster, more even heat, better efficiency and a boiler that is far less likely to break down.

Signs you may need a power flush

If any of these sound familiar, sludge is likely building up in your system

❄️

Cold spots on radiators

Patches that stay cold while the rest of the radiator warms up point to sludge blocking the flow.

🌡️

Cold at the bottom

A radiator that is hot at the top but cold along the bottom is a classic sign of sludge.

🐢

Slow to heat up

If the whole house takes an age to get warm, circulation is being restricted.

🔊

Noisy boiler or pipework

Banging, gurgling or kettling noises often mean debris is moving around the system.

🔧

Frequent breakdowns

Repeated faults and call outs can often be traced back to a dirty heating system.

🟤

Dirty radiator water

Black or brown water when you bleed a radiator is corrosion and sludge in the system.

💷

Rising energy bills

A clogged system works harder and burns more gas to heat your home.

Power flushing FAQs

Common questions about power flushing across the North East.

How long does a power flush take? +
Most domestic power flushes take between three and six hours, depending on the size of the system and how much sludge has built up. We will give you a clear idea of timing before we start.
Will a power flush fix my cold radiators? +
If the cause is sludge or debris, which it usually is, then yes. We inspect the system first so you know a flush is the right fix before any work begins.
Do I need a magnetic filter? +
A magnetic filter catches metal debris before it can settle in your system, which helps keep it clean long after the flush. We can fit one from £120 and many customers add it at the same time.
Is the price really fixed? +
Yes. We price by the number of radiators, with fixed transparent pricing and no hidden charges. You know the cost before we start.
Which areas do you cover? +
We are based in Houghton le Spring and cover Sunderland, Durham, Washington, Chester le Street and the wider North East. Call us and we will confirm we can reach you.
