ᐅ Residential ventilation system

Hello,

we have received our offer from the builder. We would like to build a KfW 79 house with 149 WoFIV. To achieve KfW 70, we were considering an additional insulation package and a controlled comfort ventilation system with central heat recovery and manual summer bypass. The ventilation unit is from Vallox, model Controlled Ventilation 090 SC, with a 4-stage setting. Designed for up to 200 m² (2,150 sq ft) of usable floor area and a maximum of 8 rooms.

Does anyone know this system or have any experience with it?

We have underfloor heating throughout the ground floor and upper floor. Heating will be provided by a gas condensing boiler from Junkers, including a 120-liter (32-gallon) hot water storage tank.

Thank you very much

I always wonder what these systems are actually capable of. I now have a small private club room in Berlin and would like to have a ventilation system installed afterwards. Is the fresh air supply sufficient? What if you have 100 people in 50 m² (540 ft²), some of whom are smoking?

Vallox is a product series from the company Heinemann and is distributed through the HVAC specialist wholesale trade. Technically, the products are sound.
