Cold spots on your radiators? Central heating taking a long time to heat up?

These may be signs of rust corrosion, debris and sludge building up in your pipework, reducing the efficiency and overall performance of your boiler and the central heating system, meaning your system may benefit from a powerflush.

The powerflush flushes water through all of your pipework, clearing away all the built-up sludge so that the water can travel through the system easily, and the powerful chemical cleans the system. Results from this procedure are instant, quickly heating up your radiators and using less power from your boiler. Read more below.

What is a powerflush?

A powerflush is a process of cleaning and maintaining a central heating system by using a specialized machine to pump water at high velocity through the system to dislodge and remove debris, limescale, and sludge build-up. This can help to improve the efficiency of your boiler, reduce the risk of breakdowns, and prolong the life of your system.

What are the benefits?

Here are some of the benefits of powerflushing:

  • Improved efficiency: A powerflush can help to improve the efficiency of your boiler by removing debris that can block the flow of water and reduce heat transfer. This can lead to lower energy bills.
  • Reduced risk of breakdowns: A powerflush can help to reduce the risk of breakdowns by removing debris that can clog pipes and valves. This can help to keep your boiler running smoothly and prevent costly repairs.
  • Prolonged system life: A powerflush can help to prolong the life of your central heating system by removing debris that can cause corrosion and damage. This can help you to avoid the need for expensive repairs or replacements.

What is the procedure of a powerflush?

The procedure for powerflushing is as follows:

  1. The first step is to drain the water from the system. This can be done by opening the drain valves on the boiler and radiators.
  2. Once the water has been drained, a cleaning chemical is added to the system. The chemical is circulated through the system using a powerflushing machine.
  3. The powerflushing machine forces the chemical through the system at high pressure. This helps to dislodge and remove debris from the pipes, radiators, and boiler.
  4. Once the powerflushing is complete, the water is drained from the system again. The system is then refilled with clean water.

Powerflushing is a relatively straightforward process, but it is important to have it done by a qualified professional. A powerflushing engineer will have the necessary experience and equipment to safely and effectively clean your central heating system.

How much does a powerflush cost?

The cost of a powerflush will vary depending on the size of your system and the level of contamination. However, it is generally a cost-effective way to improve the efficiency and lifespan of your central heating system.

How do I know if I need a powerflush?

Here are some signs that you may need a powerflush:

  • Your radiators are not heating up evenly.
  • Your boiler is making strange noises.
  • Your energy bills are higher than they used to be.
  • You have had a number of heating breakdowns in recent years.

If you notice any of these signs, it is a good idea to have your central heating system powerflushed by a qualified professional.
