Marley Deutschland GmbH offers ventilation planning according to the German ENEV guidelines of DIN1946-6. 
Ventilation planning supports you in obtaining the recommended number, type and position of ventilation devices suitable for an optimised ventilation of your property.

In order to prepare your ventilation planning, we need the number of inhabitants of the residential property or of the flat/house, the ZIP code and a floor plan of the property as a pdf file via e-mail.

We only charge 74,99 EUR for that (order here).

Along with your order, you receive a voucher for an ISO Coarse ≥ 45%/G3 filter kit, suitable for the respective type of heat exchanger.

Within 1-2 weeks after payment, we will provide a suitable dimensioning of ventilation via e-mail.

In case of any questions, please refer to +49 5031 53-611 via phone or via e-mail to
