Anti-scale dosing filters are a valuable solution for retaining solid particles in mains water and preventing the formation and accumulation of limescale within pipes, boilers, and heat pumps.
But what makes their function so essential for protecting domestic water systems and conditioning equipment?
Ecowarm: the Anti-Scale Spheres in Ecoterm's Sirio Dosing Systems
Ecowarm is a food-grade additive compliant with EN 1208:2005, the European standard for drinking water safety.
These salts—commonly found in food in significantly higher concentrations—are introduced into the water in minimal doses to deliver anti-scale and anti-corrosion benefits, enhancing the efficiency and longevity of domestic systems.
By keeping calcium and magnesium ions in a soluble state, Ecowarm ensures threshold anti-scale protection, reducing limescale deposits while preserving essential minerals in the water.
This safe and reliable technology helps protect plumbing systems and household appliances, maintaining water quality and complying with the European Drinking Water Directive 98/83/EC.
Unlike traditional polyphosphates, Ecowarm offers a dual-action mechanism: it combines scale prevention with corrosion protection through a silica-based barrier, delivering broader and more effective protection for water supply systems.
How the Anti-Scale Dosing System Works in Ecoterm’s Sirio Devices
The Sirio anti-scale dosing system works by slowly dissolving Ecowarm salt spheres as water flows through the device.
This process releases a controlled amount of salts into the water, reducing limescale formation and creating a protective film on the inner surfaces of pipes and household appliances.
This protective layer prevents scaling and corrosion, ensuring effective and long-lasting protection for the entire plumbing system.


Why Does Ecoterm Use Ecowarm Anti-Scale Salt Spheres?
Using 2 cm diameter spheres in water treatment offers several advantages over coarse crystals or powdered forms:
-
Controlled and consistent solubility: The larger spheres dissolve at a steady rate, ensuring a gradual release of active compounds and maintaining optimal water chemistry over time.
-
Reduced dust generation: Larger spheres minimize dust formation during filter operation, improving both cleanliness and the effectiveness of the water treatment process.
-
Extended lifespan: Thanks to their size, the spheres dissolve more slowly than powdered alternatives, reducing the frequency of replacements and lowering maintenance costs.
-
Improved mechanical stability: The solid structure of the spheres reduces the risk of fragmentation, preserving filter integrity and performance over time.
Easy to Replace and Fully Recyclable at End of Life
The disposable Ecowarm-S and Ecowarm-Maxi cartridges are easy to replace: simply shut off the water flow, unscrew the housing, remove the used cartridge, and insert the new one into the filter chamber.
The spent cartridge can be disposed of with plastic waste, making the used component 100% recyclable.
Choose the Ideal Anti-Scale Device for Protecting Pipes and Conditioning Equipment
The Ecoterm’s Sirio range is specifically designed to protect boilers and water heaters.
The Sirio Maxi range, on the other hand, is intended for safeguarding the entire domestic water system and serves as an alternative to more complex softening systems in installations with water hardness below 350 ppm..
