Planning central ventilation system with heat recovery, okay?

These are all disc valves in the ceiling, right?

Yes, disc valves in the ceiling.

Check if they might collide with planned lamp positions. Although I don't see anything obvious there.

Lamp positions should not collide. Good point, thanks.

Is the drawn-in furniture correct?

The furniture fits, except in Child2 (where the sofa currently stands, a wardrobe will be placed).

On the ground floor there are 40m³/h overflowing from the living room towards the bathroom and utility room. What kind of door is that "with glass panel"?. With real glass doors you have to be a bit careful, they hang closer to the floor than a normal door and then overflow can be difficult (draft and suction effects).

The door will be similar to the one in the attachment. The location in the plan also seems a bit strange to me. Exhaust air in the bathroom on the ground floor and in the utility room, and the hallway in between without supply or exhaust air. To me, it would be more logical to also install a supply air in the hallway. Or is that nonsense? Also, I had the idea to place supply air in the master bedroom on the left side, so that you definitely don’t feel a draft while in bed. In the dressing room it would also be better in my opinion if the exhaust air came more to the right towards the window to have optimized air exchange there. What do you think about my ideas?

Hello. We have received our planning for our controlled residential ventilation. In our two full-story single-family house with flat roof, a Zehnder Comfoair Q350 TR with enthalpy exchanger will be installed. I would be interested in what you think of the planning. Best regards Peter

May I ask what total price you come to including installation? Thank you

That is handled by us through the [GU] as a lump sum price.

Hello everyone,

we are also building with a general contractor and had the ventilation system tendered as an option. I cannot provide exact details on volumes yet, as we have not planned the ventilation system in detail. However, it will be a Q350-Q4??. The system itself accounts for the smallest portion of the costs (at least if I compare the online price of the device with the total price in our offer), so it probably does not matter exactly which one it will be.

It will, however, supply a living area of approximately 250 m². It needs to ventilate or exhaust 12 rooms and possibly three hallways. The building has three floors, with the basement partially built into the hillside and therefore partly a cellar.

The total price is just under €13,000.

Regards

13,000 is a SUPER price. We paid 16,000.

Do you mean the Q350 or Q450?

We have about 230 sqm of living space and since I specifically wanted Zehnder, the GU offered me the Q450. It is around 14,000.
