ᐅ Controlled Residential Ventilation for Single-Family Homes – Planning and Design Using Helios Easyplan

Hello everyone,
I am currently planning the design of the mechanical ventilation system with heat recovery. Initially, I used Helios Easyplan for the layout and will make some adjustments. Now, I am trying to find out whether the suggested supply and exhaust air outlets are positioned correctly. These were chosen based on other houses from acquaintances with a similar floor plan.
We are planning a room-air-independent fireplace and an exhaust hood. A differential pressure switch might be needed here, but this still has to be clarified with the chimney sweep.
Key details:
-Single-family house with 175 sqm (1883 sq ft) of living space spread over 2 full floors
-Concrete ceiling on the ground floor and upper floor
-Air-to-air heat pump
-Ventilation unit located in the attic
-The ventilation system will most likely be a Helios mechanical ventilation system EC 300 with 75mm (3 inch) ventilation duct
My questions for you are:
1.) I might only install the ventilation ducts in the concrete ceiling on the ground floor and on the concrete ceiling of the upper floor with appropriate ceiling outlets. Since I am unsure if my budget will be sufficient, I want to prepare everything this way (only ventilation pipes and ceiling outlets, close off ducts in the attic, plaster over ceiling outlets) and then decide whether to complete the system later by installing the distributors, unit, and the rest. I don’t want to lose the option of a mechanical ventilation system in the future and hope to prepare everything with a relatively low budget for now.
The siphon, electrical supply, and empty conduit will also be prepared.
2.) Preparation aside, the openings for supply and exhaust air must be made ready. What do you think about these locations? The bedrooms are supposed to have both supply and exhaust lines to be able to increase airflow to about 60 m³/h (35 cfm) while keeping noise levels low.
I am happy to receive all kinds of suggestions, criticism, and tips and will consider them in my planning.
Attached are the floor plan with supply and exhaust air, and the Helios design.
Thanks in advance.
Best regards,
Almo

So you consider such a preparation a good idea to avoid possibly not being able to start up the ventilation system immediately? In my opinion, the costs of a mechanical ventilation with heat recovery are largely determined by the installation and the ductwork. With only a small additional expense compared to a basic installation, you can complete the system right away. However, if you do a lot of the work yourself and purchase materials cheaply, it might be different. So, it depends on the individual case.I would avoid placing the ceiling outlet in the dining room directly above a seating area if possible. In winter, that can be uncomfortable. It’s better to position it more towards the edge.

thanks for your advice.
The system will be installed entirely as a DIY project.
Well, the ventilation ducts with ceiling vents will cost me about 1300€ (approximately 1400 USD).
The complete ventilation unit will be around 6000€ (approximately 6400 USD). I’m calling a supplier today.
As already suggested by @Mycraft, I have updated the drawings and marked the duct routing as I plan to install it. I have confirmed with a structural engineer that running ducts horizontally under load-bearing walls is acceptable; he is now reviewing the drawings.
Since the longest ventilation duct causes the highest pressure loss, should I include a loop in the shorter ducts? Is that advisable?
Best regards,
Almo
