Find the right LIMex model for you

Find the right LIMex model for you

The right decision in 60 seconds

Six quick questions about your home, water hardness and usage – and you’ll know which LIMex is right for you, how long the anodes will last and whether the full 5-year guarantee applies to your situation.

The calculator works with the same technical parameters that we use in a consultation – hydraulic retention time, anode surface area, ion output per liter and regional water hardness. The result is therefore not a rough estimate, but exactly the recommendation that we would also give you in a personal consultation.

Your answers determine the following:

  • Your living situation determines the expected peak flow rate and annual consumption
  • Your water hardness determines the required anode capacity
  • Their occupancy (permanent or seasonal) influences which model makes economic sense

The recommendation is based on the information you have provided. For binding dimensioning – especially for commercial properties, several parties or atypical water conditions – we recommend a personal consultation with on-site measurement. We will then check the water pressure, pipe diameter, installation and actual hardness values.

Your result is ready?
Let’s talk. We will be happy to provide you with a non-binding quote based on your key data – including installation by our local partner or as a pure device delivery, depending on your requirements.
