Radiator in the new building?

Good morning,
we are going back and forth. New build or existing property. However, for various reasons, we will take another 2 to 3 years to make a decision.
In the meantime, we are mentally planning our new build. The construction or renovation topic is really our hobby – we love wandering through exhibitions in hardware stores and keep a close eye when we visit others.
Nevertheless, as mentioned, no new build is planned yet, no conversation with a builder has been held, … everything so far is just daydreaming.
And about two of these things, I would like honest feedback from experts, current builders, and those who have been living in their new builds for some time.


    [*]Heating

We currently imagine installing radiators throughout the new build. No underfloor heating.
For the radiators, we could imagine underfloor heating in the tiled areas (kitchen and bathroom).
Heating would, of course, be with gas. We are currently not 100% convinced by a geothermal heat pump anyway.
We currently rent a detached single-family house built in the mid-90s. Gas heating. Underfloor heating on the ground floor, radiators on the upper floor. Separate heating circuits. However, the underfloor heating is now already 20 years old and operates with a flow temperature of around 35°C.
Actually, I like the underfloor heating. But what speaks against it for me:


    [*]Inertia. Especially in the transitional season I was annoyed by that. Also, in the evening in the living room, I like to quickly turn up the heat so that it gets very cozy warm. That doesn’t at least work with our old underfloor heating. If I turn it up, I’m long in bed by the time the room actually gets warmer.
    [*]We and our children sleep in the cold, meaning with windows open. Now I wonder how that is supposed to work with underfloor heating. During the day the kids sit in their warm room, even if the underfloor heating were turned off and the window opened, it doesn’t really get cold in the room because of the inertia of the underfloor heating…
    [*]I love to stand next to a hot radiator and warm myself, preheat my duvet on it before going to sleep, or dry some shoes or clothes.

What do you think about that? Basically, I do appreciate underfloor heating very much, especially the aspect of the low flow temperature and thus the possibility to switch at some point in 20 years over to geothermal drilling or similar…

2. Controlled residential ventilation.
We would possibly leave it out because we have heard that it makes the room climate (temperature) the same in all rooms. As I said, our bedrooms are cold and the living room warm.
We air sufficiently in spring and summer. We have, so to speak, an open house – all windows and doors are constantly open. We like the fresh summer air and love the sounds, the birds chirping…
In winter, however, our ventilation behavior in the living area and kitchen leaves much to be desired.
What do you think?

We gladly welcome open and honest answers. Nothing hurts us yet, nothing is lost, everything is open and possible.

We are grateful for every thought-provoking idea or experience value!

Hello,
Why does gas have a unique selling point here?
Heat pumps each require certain framework conditions, differentiated by type of source (air, geothermal, water).
A requirement cannot be more diffuse! You can’t have everything for almost no cost, but must set priorities.
Every solution has advantages, but also disadvantages. "If you want one thing, you have to like / accept the other" or be able to deal with it!
In 20 years, you may possibly no longer be allowed to extract geothermal energy for free. Furthermore, by that time you will already have consumed so much energy that switching considering the remaining useful life and inflation probably no longer makes sense.
How is "have heard" scientifically reliable? Not at all! This insight indicates insufficient planning/dimensioning. Probably saved a few € on proper and precise MEP planning or a general contractor / main contractor or developer project.
You basically cannot act more energy-unfriendly unless you have an open budget!
You don’t even master the current situation, so it probably won’t get significantly better in the future.
Careful, precise planning/dimensioning by a sales-independent, objective MEP planner/energy consultant is urgently recommended!

Best regards

They can harness environmental energy, which is not possible, for example, when using gas, heating oil, pellets!
Truly a lasting, reliable prognosis/recommendation for others without knowledge of the specific conditions and framework!
What is helpful for A, works barely for B and turns into a money pit for C!

Best regards.

Well, gas is somehow environmental energy after all

My intention was not to convince the OP of anything. He wanted food for thought, and I can provide that.
The OP also spoke of a new building, so I assume it is at least close to Kfw 70. There are some requirements to fulfill, after all.

And after 3 months of extreme weather, I can very well estimate how high MY heating demand will be.

Thank you very much for the detailed response!

You can gladly send me the ventilation system via private message. How does that work here?

Exactly because with the request "radiator" one is such an exotic case, I wanted to ask here and maybe get answers as to why this is no longer an issue in new buildings. I am of course aware of the supply temperature and the visual effect. But are these the only real reasons why everyone chooses underfloor heating?

Wow, you really pay very little per month! Do you also have a fireplace? Aren't those values also promoted by the geothermal faction?

Controlled residential ventilation: I don’t want to miss it, and in summer you can simply turn it off and open the windows wide. You will notice, you can definitely sleep without open windows in winter! And what DerDa writes about diapers also applies to all other scents of human life.

I also don’t want to miss underfloor heating. This is the first time in my life that I live with underfloor heating; I only knew it from visits before.

@DerDa: Are you serious now? 3 months as a consumption forecast? €uro already wrote, conditions are missing, but 35€ seems very high since it wasn’t the winter months!
And with the 12k€ the gas house connection and the solar system (or whatever measure you have) are probably already offset?
