Central Heating Powerflush: What It Is and When You Need One
A central heating powerflush cleans sludge and rust out of your pipes and radiators. Over time, this dirt builds up and makes your system work harder. A clean system heats faster and puts less strain on the boiler.
What is a central heating powerflush?
An engineer connects a powerful pump to your heating system. Clean water and a cleaning agent then flow through the pipes at speed. This pushes out the sludge that has collected over the years.
Signs you may need a powerflush
Look out for these warning signs.
- Radiators that are cold at the bottom
- Cold spots in the middle of a radiator
- Black or brown water when you bleed a radiator
- A noisy boiler or pipes
- Slow heating, or a boiler that keeps shutting down
Why it helps a new boiler
Dirty water can damage a new boiler. For this reason, a powerflush is often done when a new boiler goes in. It protects your investment and can help keep your guarantee valid.
How long does it take?
It depends on the size of the system. Most homes take a day. Your engineer will explain the process before they start.
Keeping the system clean
After a flush, an inhibitor in the water helps stop rust returning. A yearly boiler service also helps. Read about the importance of servicing radiators and boilers before winter.
