Flushing the central heating system

How does the process of flushing your central heating system work?

Flushing a central heating system, also called a power flush, is a thorough cleaning process. Your heating system is connected to a special pump that flushes water and cleaning agents through the pipes and radiators at high pressure.

Our specialists will inspect your central heating system to identify any problems and determine the need for a flush.

Using professional equipment, dirt, sludge and rust are completely removed from the system.

After flushing, we fill your system with clean water and check for leaks and proper functioning.

The system is delivered fully functional again and optimally configured.

Why is flushing a central heating system important?

A dirty heating system can lead to all kinds of problems, such as:

  • Lower efficiency: Your boiler has to work harder, resulting in higher energy costs.
  • Uneven heating: Radiators do not heat up evenly everywhere due to accumulated dirt.
  • Faster wear: Parts of your system can be damaged by rust and sludge.
  • Higher repair costs: Regular maintenance, such as flushing, prevents expensive repairs or replacement of parts.

Regularly flushing your central heating system extends its lifespan and saves costs in the long run.

Very happy with the work they did in our apartment. They completely renovated our bathroom and also took care of walls, plastering, painting, tiles, radiators, and ventilation. Everything was done with great attention to detail and finished faster than expected. The prices were fair and clear. The team was friendly, professional, and very expat friendly, which made communication easy. We are really pleased with the final result and would definitely recommend them.
