You can find this info on your water bill. If you don't know it, you can use the average value of 50 m³ per person per year.

°dH
The hardness you want to achieve. The more you reduce the hardness, the more salt you will need. Higher values will result in lime deposits in your pipes and appliances.

„Wir waren auf der Suche nach einer Wasserenthärtungsanlage für unser Mehrfamilienhaus. In der Vergangenheit war ein ähnliches Projekt aufgrund der üblicherweise sehr hohen Anschaffungskosten gescheitert. Bei *** haben wir nun eine hochwertige Lösung gefunden. Das Gesamtpaket hat perfekt gepasst - von der Beratung bis hin zum fachgerechten Einbau und das zu absolut übersichtlichen und nachvollziehbaren Kosten. Die Anlage ist nun seit zwei Monaten in Betrieb, läuft einwandfrei und wir sind vollkommen zufrieden. Ich schreibe selten Bewertungen - aber auf die Art kann ich nochmals "Danke" sagen.

Calculate the optimal capacity of your water softener – simple and precise

Are you looking for an effective solution to reduce water hardness in your home or business? Our user-friendly online calculation tool allows you to quickly and easily determine the optimal capacity of your water softening system. This calculator takes your individual needs into account and ensures that you find the perfect system for your requirements.

Why calculate the capacity of your water softener?

The correct sizing of your water softening system is crucial to ensure maximum efficiency and longevity. A system that is too small will need to be regenerated more often, which not only uses more salt but also shortens the lifespan of the system. A system that is too large, on the other hand, can result in unnecessarily high purchase costs. With our capacity calculator, you can ensure that your system is a perfect fit for your water consumption and water hardness.

How does our capacity calculator work?

Simply enter your average daily water consumption and the hardness of your water in degrees German hardness (°dH). Our calculator uses this information to calculate the necessary capacity of your system in cubic meters per day. This will help you choose a system that will effectively improve your water quality without wasting energy and resources.

Advantages of an optimally dimensioned water softening system:

  1. Increased efficiency: A properly sized system maximizes the efficiency of the ion exchange process and reduces salt consumption.
  2. Cost savings: Avoid unnecessary operating costs due to frequent regenerations and high maintenance requirements.
  3. Longer service life: By minimizing the load on the system, you extend its service life and improve overall performance.
  4. Improved water quality: Achieve consistently soft water that reduces the formation of limescale deposits and associated problems in pipes and household appliances.
