Hello!
We are planning to have a house built and are currently still in the initial planning phase. However, after a conversation with the architect, we are already considering heating options.
We are not building a KfW-certified house, but one strictly following the Energy Saving Ordinance. It will have about 220m² (2,368 sq ft) of living space plus a basement.
In various building specifications from contractors (we are having a turnkey build), we often see heat pumps that require an additional outdoor unit beside the system in the utility room. For aesthetic reasons, we are not very keen on that.
What alternatives are there for this kind of setup?
Gas heating combined with solar (the gas connection is available)?
Geothermal heat pumps?
Or other air-to-water heat pumps that do not require an outdoor unit?
We will probably have a hipped roof (with regard to solar panels). With a flat roof, the panels look quite unattractive.

High bathroom temperatures often require wall heating. In new buildings, even a small breeze can raise the room temperature. In the living room, we manage 23°C (73°F) without the floor getting warm. We already have to put rugs under tables and similar spots because otherwise, your feet get cold. I thought that was the purpose of underfloor heating.
We use gas and would do the same again.

By the way... back to the original topic. Is gas combined with mechanical ventilation with heat recovery actually a sensible combination? Or is the mechanical ventilation with heat recovery mainly recommended only with heat pumps?

This should be considered independently. Gas systems usually require a low initial investment. Heat pumps are generally more expensive because multiple parties profit from the process.
I personally cannot comment on controlled residential ventilation. Researching online, those against it are often people who don’t have one, while those who do believe it’s absolutely necessary.
It is energy-efficient, but it often only pays off after a long period.
However, you always have fresh air and no need for forced ventilation. But you should budget around 10,000€ (approximately 11,000 USD). If I were building new and had the budget, I would install one.

Someone who has never had it doesn't know what it's like with it.
