What Is Chemical Power Flushing?
Chemical power flushing is a deep clean of your radiators and central heating system which is designed to get rid of sludge, rust and other debris that may have accumulated in your pipes, radiators, heat exchanger, pumps and boiler over time.
The process is done using a specialist flushing machine and involves attaching it to your system and pumping cleaning fluid around it. The liquid, whilst high velocity, is low pressure meaning that no damage is caused to the components.
Signs You Need a Chemical Power Flush
As well as after a boiler service or repair where chemical power flushing may be recommended, the following are indications that your system needs attention:
- Unusual noises coming from your boiler.
- Radiators taking a long time to warm up.
- Hot water taps fluctuating between hot and cold.
- Radiators having cold patches.
- Your boiler needs to be restarted regularly.
- Pipework vibrating or making banging noises.
- White cloudy tap water can indicate limescale in your system.
- Your energy bills have steadily increased without using your system more.
- Brown or sludgy water is present in your system.
- Water leakage from boiler (combi).
In addition to these signs, it is recommended that you have your system chemically power flushed once every 5 years, or when you have a new boiler installed.
Why Have Your System Power Flushed?
There are a number of benefits to having your heating system power flushed including:
- Improve the efficiency of heating system.
- Reduce energy bills.
- Prevent blockages in your pipework.
- Increased radiator convection.
- Increased hot water temperatures.
- Reduce the risk of boiler breakdown and increase lifespan.
- Prevent cold spots on the radiator.
- You may find that the better flow of water around the pipes reduces pipe and boiler noise.
How Often Do I Need Powerflushing?
If you are having an annual service of your boiler as recommended, power flushing should only be required once every 5 years. Additionally, a system flush is required when a new boiler is installed – we include this as standard with all boiler upgrades.
