ᐅ New construction with underfloor heating, mechanical ventilation, and air conditioning

Hello 🙂

First of all, we haven’t planned a floor plan for our future house yet, so we don’t have any idea of the required dimensions. I’m more interested in getting an idea for our wish list.

As mentioned in the title, for the new build we want underfloor heating, a centralized ventilation system, and air conditioning. From what I have read so far, it seems like I would need three separate systems for this... for example, an air-to-water heat pump for regular heating (hot water and underfloor heating), a device for ventilation, and a standalone split air conditioning system (several indoor units), since ventilation alone doesn’t provide real air conditioning. I have also read about cooling through the underfloor heating system, but I imagine that would be uncomfortable, as I usually walk barefoot or wear socks inside the house 😉

Am I on the right track with this approach, or are there good combination units that can cover these functions? Has anyone experienced this setup themselves?

We also plan to install photovoltaic panels on the roof, so electricity consumption is not my primary concern when comparing individual systems versus a combination unit, but rather the space requirements. My server cabinet also needs power and cooling 😎

Thanks and best regards

In combination, it would actually be ideal. Of course, the execution must be done properly.

We had the same goals for our new build as you!
We declined underfloor cooling for similar reasons. Therefore, using an air conditioning system is unavoidable.
For mechanical ventilation with heat recovery and heating, you can use combined units. For example, Stiebel Eltron / Tecalor.

Wouldn't it be sensible to design a new building in a way that eliminates the need for air conditioning from the start?

Can you explain that? Characters

Of course, our house should be insulated as well as possible, but for us, air conditioning is simply part of the plan when building new. Especially for my home office (4 out of 5 days a week), I think it’s a must-have.
