LIMESCALE PROTECTION
IS ALSO
CLIMATE PROTECTION

The BIOCAT limescale protection system is an environmentally friendly alternative to other water treatment systems, as it does not require the addition of salt, phosphates, or other chemicals during operation. These chemical-free limescale protection systems do not alter the natural mineral composition of drinking water, and the rinse water remains uncontaminated. This means that the surrounding water environment is not subjected to environmental stress.

Limescale deposits result in increased energy consumption

Lime protection is also beneficial for the climate because it prevents lime deposits in pipes and on heat exchangers. Limescale deposits diminish the heat transfer efficiency in pipes and on heat exchangers, negatively impacting a household's CO2 balance. Even a 6 mm thick layer of lime can lead to increased energy consumption of up to 50 percent.

There are many reasons why a BIOCAT lime protection system benefits the environment:

  • No salt or phosphates are added, thereby protecting the water environment.
  • By preventing lime deposits, high energy efficiency in pipes and plate heat exchangers is preserved.
  • The systems only require power for thermal disinfection; otherwise, no energy is used.
  • Granules are replaced only every 5 years, eliminating resource waste.
  • BIOCAT systems do not produce any environmentally harmful wastewater.
  • The flush volume is lower than that of a conventional water treatment system.
  • High-quality materials ensure a long lifespan and no resource wastage.

Therefore, limescale protection is crucial for energy-efficient hot water treatment. A significant portion of energy consumption in private households, 75%, is for space heating, while 12% is for water heating. To protect against legionella, water should be heated to a constant temperature of at least 60°C. If pipes and heat exchangers become calcified, more and more energy is required to heat the water to the prescribed temperature.

Limescale deposits create a "limescale heat barrier"

Calcium-rich water quickly forms an insulating layer of lime, a so-called "limescale heat barrier," which inhibits heat transfer from the heat exchanger to the drinking water. It often takes a long time before the problem is noticed, and by then, damage has occurred: Lime deposits create additional costs due to increased electricity requirements, faster wear and tear, etc.

Here's how WATERCryst works to promote the UN Sustainable Development Goals:

WATERCryst is committed to ensuring sustainable consumption and production patterns. Specifically, this is achieved by replacing existing water treatment systems, which release harmful substances directly into the environment, with chemical-free and more sustainable systems. The wastewater from a BIOCAT limescale protection system is thus clean water and contains neither salt nor other chemicals.

Reduced energy consumption: Limescale buildup in boilers, water heaters, heat exchangers, etc., diminishes heat transfer and significantly increases energy consumption. In contrast, effective lime protection with a BIOCAT lime protection system prevents heat loss, thereby having a significant positive impact on the CO2 balance.

Sustainable consumption and production: Fewer limescale deposits mean extended lifespan and fewer replacements of both water systems, appliances, and household equipment. Thus, it contributes to more responsible consumption and production.

Reduced transportation needs: The systems do not require service or delivery of additives such as salt. Thus, we reduce the need for transportation. Likewise, we manufacture and assemble all our systems in Europe, thereby reducing transportation needs, logistics, and the associated CO2 footprint.

In other words, there is a solid, green economy and increased sustainability in a chemical-free BIOCAT lime protection system: Lower energy and heat consumption, no polluting chemicals, and reduced transportation and logistical needs.
