Acid descaling treatment removes limescale and mineral deposits from heating and cooling equipment to restore efficiency and performance. Even small amounts of scale can significantly reduce heat transfer efficiency, increase energy consumption and shorten equipment lifespan. Our acid descaling services are delivered safely and effectively across commercial and industrial systems.
What Is Acid Descaling Treatment?
Acid descaling treatment is a controlled chemical cleaning process used to dissolve and remove scale and mineral deposits from system components such as boilers, heat exchangers, cooling towers and hot water calorifiers.
At National Hygiene Services Limited, we are experienced in acid descaling and specialist chemical cleaning techniques for a wide range of industrial and commercial heating and cooling machinery.

Why Acid Descaling Is Important
Scale build-up significantly reduces system efficiency and increases running costs. It is estimated that:
- 1.5 mm of scale in a hot water cylinder can reduce efficiency by up to 15%
Removing scale and preventing future build-up through measures such as ion exchange water softening can:
- Reduce utility and energy costs
- Improve heat transfer and system performance
- Extend equipment lifespan
- Deliver measurable environmental benefits
For larger systems or new installations, chemical cleaning may also be required. Further details can be found on our Pre-Commissioning Chemical Cleaning service page.
Our engineers are not only fully trained and experienced in all aspects of acid descaling services for boilers, heat exchangers, cooling towers and hot water calorifiers, but also in ensuring the safety of everyone whilst treatment is carried out. All engineers carry the CSCS passport to safety and are all enhanced DBS checked to ensure confidence when working on site and in areas with vulnerable people

Acid Descaling Treat FAQ’s
What is acid descaling treatment?
Acid descaling is a chemical cleaning process used to remove limescale and mineral deposits from heating and cooling system components.
How does scale affect system efficiency?
Even small amounts of scale reduce heat transfer efficiency — 1.5 mm of scale can reduce efficiency by up to 15%.
Which equipment can be acid descaled?
Boilers, heat exchangers, cooling towers and hot water calorifiers can all benefit from acid descaling treatment.
Is acid descaling safe?
Yes. When carried out by trained engineers using controlled procedures, acid descaling is a safe and effective method of restoring system performance.
How can scale build-up be prevented?
Prevention measures include water softening, ongoing water treatment and regular system monitoring.
