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

What is unclear? Just extend the ceiling outlet down to the suspended ceiling. That way, you have quite a bit of freedom in deciding where to place it.I would have planned to lower the ceiling outlet quite far down and then run the duct and outlet under the ceiling to the desired location!?

Yes, that’s exactly what I mean. You extend the ceiling outlet using the appropriate methods. This way, you can freely decide where to place it since the ceiling has been suspended.Today, I find myself quoting you everywhere.
So, do you consider such preparation a good idea, even though the ventilation system might not be put into operation immediately?
I still need to plan for supply and exhaust air. I’ll look for suitable roof penetrations, but I won’t install them right away.
Good, not good. You need to know that. I am always in favor of controlled residential ventilation. It makes living in the house easier.
If the budget doesn’t allow for it right away, preparing the ducts is still quite useful. However, I would definitely cap the ducts while they are unused—that is, seal them airtight until the system is installed.
This helps prevent any possible contamination.
What do you think is missing in the building systems thread? Off the top of my head, I can’t think of anything else to add.

Good or bad, you need to decide. I am always in favor of mechanical ventilation with heat recovery. It makes living in the house much easier.
If the budget is tight, preparing the ductwork in advance is still quite useful. However, I would definitely seal the ducts with caps while they are unused. In other words, airtight closure until the system is installed...
Yes, I want to seal them with caps and wrap tape around to be on the safe side. If I do better in price negotiations and am more diligent with self-labor, the mechanical ventilation system will be installed right away, that’s my wish. Then I can also integrate it into the building automation system.

Yes, good question… what else could be included?
Maybe some good experiences, or which types of cables are sufficient in a single-family home. For example, I want to run an NYM 5x1.5 cable to every room to have three circuits—constant power and two switchable circuits, for instance. You probably also know about lighting and whether DALI is worthwhile or just KNX… well, maybe that’s good content?!
But it could also get too detailed?
Best regards
