Power flushing is something that we either forget about or don’t know anything about so that’s probably the reason you are reading this. Maybe you have had an engineer to your property and they have told you that your system requires powerflushing.

A powerflush will normally be diagnosed after a boiler service. If you have your boiler serviced annually, then a preventative powerflush should only be required every 5-6 years and should be completed by a fully qualified engineer.

Powerflushes may also be completed before you have your boiler swapped. This is because it helps to prevent contaminating your new boiler with sludge and debris which could potentially damage your new boiler.

There are several signs you need to watch out for that may indicate you need a powerflush:-

• Cold areas on radiators e.g. at the bottom

• Excessive noise from the boiler or the heating system pump

• Discoloured water when you bleed the radiators

• Heating is slow to warm up

• Cloudy tap water (limescale in the system)

• Some radiators struggle to heat up as well as others

• Radiators cold but pipes are hot

• Boiler regularly shuts down and needs restarting

• No water escapes when you bleed a radiator

• Noisy radiators and or / boiler

• Small leaks in radiators.

After your boiler has been powerflushed you may experience that your radiators will get hotter a lot more quickly, your boiler will make less noise, and also it will become more efficient potentially saving you money.

When the engineer conducts the powerflush he will connect a pump to your central heating system. If it’s a Combi it will be connected at the pump head but if it’s a System boiler it will be connected at the circulation pump. This pump will push special chemicals through the pipes, boiler, and radiators.

A powerflush includes a chemical that will remove sludge and rust, a descaler to remove limescale and corrosion inhibitor to help prevent future rust from forming. The engineer will collect and dispose of any contaminated water, debris or particles that they remove from the system.

In some cases, where the system is too full of sludge and debris, you may find it more cost effective to change your whole system. A powerflush will not fix broken parts if a blockage in your system is responsible.

The cost of a powerflush can vary massively depending on the company you choose. Here at T&S Heating, our prices start from £299.99
