Hello everyone,
we are currently planning to build a relatively large single-family home (living area, including the rooms in the basement used as living space, around 450 sqm (4844 sq ft)).
In addition, we are building an outdoor pool, which should also be heated from April to October. Ideally, it should not have a separate heating system but be integrated into the overall heating concept.
I generally prefer to invest a bit more upfront in order to have lower ongoing costs.
The construction companies mostly recommend an air-to-water heat pump because it requires the least effort for them (no chimney needed, no solar system required).
However, I am somewhat skeptical about heating such a large house and the pool only with a heat pump.
Therefore, the question is:
What would be a reasonable solution for the heating? Heat pump? In combination with solar thermal or photovoltaic? Gas condensing boiler with solar thermal or photovoltaic? Or perhaps even a small combined heat and power plant?
I would really appreciate any input on this.

Do you have any photos and a floor plan of your amazing project?
I would be really interested.https://www.hausbau-forum.de/threads/bauhaus-villa-gebaut-aus-beton-mit-Kerndämmung-erfahrungen.28733/
This is his exciting project.
@Rick: Wow, great house! I need to read everything carefully tonight.
What is your recommendation regarding cooling?
The building company says the "cheap" options are no good, meaning a reversible heat pump is not suitable because the floor would be cold in summer, and using the mechanical ventilation system for cooling would also not work due to condensation causing moisture and mold.

Thanks, kmk123.
Regarding cooling, the construction company is correct. Insufficient capacity and cooling through the floor quickly cause dew point issues.
Mechanical ventilation with heat recovery including "cooling" only allows for limited buffering. Cooling through ceilings and walls makes more sense. The best solution is a proper air conditioning system, for example, fan coils.
We have a much higher airflow rate with our mechanical ventilation system (sometimes 10 times above the standard) and can therefore also cool via air with a central air conditioning unit.
Consider consulting an engineering firm for heating, ventilation, and sanitation (HVS) systems. Everything needs to work together.

After all, you're probably spending between 2-3 million just on the house. Hello
Surely there is still some budget left to make the yacht in the Bahamas a bit bigger.
OK, it wasn’t entirely clear to me why a geothermal heat pump was ruled out. I suspect bad advice there.

We do not know what the original poster ultimately pays or how high the budget is.
Just because someone is willing to spend more on a house than others does not mean they live extravagantly. And even if they do, it is a matter of personal freedom.
I find the comment quite odd and driven by envy.
With a standard heat pump or geothermal heat pump, it is not possible to heat a property with a pool. You need larger units, which are correspondingly more expensive. Aside from whether drilling would even be permitted...
Usually, you rely on a gas boiler or, for large facilities like hotels or swimming pools, on combined heat and power units.
