water softeners: no chance for hard water!
Do you live in Berlin and struggle with hard water? Calcareous deposits in the bathroom and kitchen, rapid wear of household appliances and dry skin are the usual consequences. Soft water systems are the solution, because they provide soft water, protect your technology and save energy.
- Cleanliness and freedom from lime in bath and kitchen
- Softer, radiant laundry
- Improved taste of coffee and tea
- Lower your energy costs
- Softer skin and smoother hair
- Longer life span of your devices
- Protection against pipe bursts and line damage
Water softener: the easy rescue for household appliances
In Berlin, we suffer from particularly hard water, which not only causes annoying calcium deposits, but also pollutes your household appliances. Dishwashers, washing machines and even the heating system can be damaged by calcium deposits, resulting in a shorter lifespan and higher maintenance costs. Lime settles in the appliances, worsens their efficiency and increases energy consumption. A soft water system in your home can help here. It removes calcifying minerals from the water so that your devices are protected from damage and function optimally.
Feel good and save money
thanks to a soft water system
It's not just your household appliances that benefit from soft water. Your skin will also feel softer and smoother after showering and your hair will shine silkier. When washing, you can look forward to softer laundry. And even your tea or coffee will completely rediscover their aroma. Another important advantage is significant energy savings. This is because calcium deposits in water pipes drastically increase energy consumption. Investing in a soft water system therefore not only means greater comfort and quality of life, but also significant cost savings.

Here you can find frequently asked questions and answers on the topic of domestic water technology in Berlin.
Wie kann ich feststellen, wie hart mein Wasser ist?
Z.b. indem wir bei dir eine Wasseranalyse durchführen. So können wir den genauen Härtegrad und andere Parameter deines Wassers bestimmen und gucken ob und wie wir dies optimieren können - z.B. durch den Einbau einer Enthärtungs- oder Weichwasseranlage.
Was mache ich, wenn meine Anlage ein Problem meldet?
Keine Sorge! Du kannst uns jederzeit kontaktieren. Wir bieten einen umfassende Wartungs- und Reparaturservices für nahezu alle sanitären Systeme in deinem Zuhause an.
Ist weiches Wasser besser für meine Haushaltsgeräte?
Ja, weiches Wasser verhindert Kalkablagerungen in deinen Geräten, wodurch sie länger halten und effizienter arbeiten. Deswegen bieten auch Weichwasseranlagen viele Vorteile. Lass dich hierzu gerne von unseren Wasser-Experten beraten.
Wie oft muss ich meinen Hauswasserfilter wechseln?
Das hängt vom jeweiligen Modell und deinem Wasserverbrauch ab. Im Durchschnitt empfehlen wir, den Filter alle 6-12 Monate zu wechseln.
Was macht der Grohe Sense Guard?
Der Grohe Sense Guard überwacht deinen Wasserverbrauch, erkennt Leckagen und kann bei Bedarf die Wasserzufuhr automatisch abschalten, um Wasserschäden zu verhindern.
Warum sollte ich mich für eine Grohe Blue Armatur entscheiden?
Die Grohe Blue Armatur liefert dir gekühltes, gefiltertes und (bei bedarf) kohlensäurehaltiges Wasser direkt aus dem Wasserhahn. Das spart Platz in deinem Kühlschrank, reduziert Plastikmüll von Wasserflaschen und erspart dir das lästige Kisten geschleppe. Die Grohe Blue Armatur funktioniert ähnlich wie ein Soda-Stream mit dem Vorteil, dass dein Wasser perfekt gekühlt und von Schadstoffen befreit ist und du kein zusätzliches Gerät rumstehen hast. Dein stilles oder sprudelndes Wasser kommt direkt aus deiner Küchenarmatur.
Was ist der Unterschied zwischen einer Enthärtungsanlage und einer Weichwasseranlage?
Beide Anlagen reduzieren die Wasserhärte, aber auf unterschiedliche Weise. Enthärtungsanlagen tauschen Calcium- und Magnesiumionen gegen Natriumionen aus, während Weichwasseranlagen das Wasser mit Salz behandeln, um Kalkablagerungen zu verhindern.
