Internal Radiator Cleaning – an Effective Way to Restore Heating System Performance

Over time, heating systems accumulate rust, limescale, and sludge. As a result, radiators start heating unevenly – the bottom stays cold while the top becomes hot. This is a clear sign that the system is clogged. In such cases, external maintenance alone is not enough – an internal radiator cleaning procedure is required.

How the Cleaning Is Done

Radiators are cleaned using “Rothenberg EDM” equipment – a professional device designed to flush heating systems without dismantling them.
The machine sends air pulses combined with a special cleaning fluid through the system, creating strong flow shocks. These impulses help detach sludge, rust, and other deposits from the inner walls of pipes and radiators, flushing the system until clean water runs through.

This method:

  • Does not damage pipes or radiators;
  • Effectively removes accumulated deposits and sludge residues;
  • Restores even water circulation;
  • Improves heat transfer and reduces energy consumption.

Protection After Cleaning

After cleaning, it is essential to apply a system protection agent – a special corrosion and scale inhibitor solution.
This forms a thin protective layer on the inner surfaces, which:

  • Prevents new deposits from forming;
  • Stops corrosion processes;
  • Extends the lifespan of the heating system.

In short:
✅ Cleaning with “Rothenberg EDM” uses air and water pulse technology.
✅ Most deposits and sludge are removed.
✅ With protective treatment, radiators stay clean and efficient for many years.
