Ventilation planner – plan the right system for your home

How many ventilation units do you need, which model suits each room and where should they be placed? The free JESSP planner guides you through rooms and requirements to make an initial selection.

How planning works

1. Record your rooms

Enter room type, dimensions and relevant building information.

2. Check requirements

Consider airflow needs, supply and extract rooms and possible positions.

3. Choose units

Compare DZ, Easy+, Vario 160 and Vario 110 for the room.

4. Use the result

Prepare a shopping list or request personal planning and a quotation.

Units considered

  • Eco Smart DZ
  • Eco Smart Easy+
  • Eco Smart Vario 160
  • Eco Smart Vario 110
  • Matching filters, external hoods and pipe extensions

Language and planning scope

The planner currently operates in German and uses the simplified German DIN 1946-6 approach for residential preliminary planning. It does not replace project-specific professional design or applicable local requirements. Suitability depends on the building, wall construction, wiring, combustion appliances and structural/electrical conditions.
