The stated area of approximately 41 to 53 m²^* is a guideline for standard room height and normal insulation standards, not a binding design. Room height, insulation standards, window areas, shading, and the number of people and devices determine which power class is suitable for your property. We will check the appropriate design for your property upon request.

* Guideline based on the cooling capacity specified by the manufacturer, at a standard room height of approximately 2.5 m, normal insulation standards, and average solar radiation. Different conditions on site, such as large window areas, sloped roofs, or a high number of people, may require a different power class. The binding design is carried out on a property-specific basis. For a professional design of your property, please contact us.
