We are planning a new build. The footprint of the house: 10 x 14.5 meters (33 x 48 feet). Ground floor: a household of two retirees. Upstairs, a self-contained apartment for one person.
Heating options / power supply:
a) standard gas boiler
b) ground source heat pump, electricity from the grid
c) ground source heat pump, electricity from own photovoltaic system and possibly battery storage
d) ground source heat pump, electricity from own photovoltaic system, battery storage, and possibly cloud services
So far, we have no information about the price difference between purchasing a standard gas boiler and a ground source heat pump.
Two construction companies said a standard, affordable gas heating system would be sufficient since houses today are so well insulated that the heating demand is not very high. But is that future-proof?
And if a heat pump is chosen, is it better to have electricity supplied from an own photovoltaic system? With or without storage? In addition, a cloud solution?

You can do that if you want; it’s your heat pump.
But basically, no. Many of the components inside the unit (some of which also appear in the list above) can fail. Additionally, there are parts like the hydraulic system outside the unit itself.
Here is a picture showing the components inside a brine heat pump. Other types of heat pumps basically have the same parts, sometimes more, sometimes fewer.

What does "no" maintenance mean? After a few years (estimated from 5 years?), even the best heat pump will probably have some parts break down or wear out, right? What are your experiences with this?
You have installed the Geisha yourself as well? This is actually the Panasonic WH-MDC05F3E5, isn’t it? Because I couldn’t find any information on it otherwise. At first, I thought Geisha was a manufacturer I hadn’t heard of before. Yes, the Geisha is the WH-MDC05F3E5 from Panasonic. However, only the successor model WH-MDC05H3E5 is newly available.
Our consultation was very contradictory. Our heating installer, a subcontractor of the general contractor (GC), was eager to sell the Junkers air-to-water heat pump and praised it highly. However, the GC himself recommended a gas boiler, believing that heat pumps tend to have more errors and are more prone to defects, as well as being replaced more often and not lasting as long. He said from experience that a gas boiler usually operates without major issues for around 15 years, whereas air-to-water heat pumps do not.
So, being conservative, we chose gas. K.

It's definitely a bit more. Even the dimensions (performance values) cannot be overlooked. A large and expensive refrigerator only consumes about 0.5 kW, while with heat pumps we are looking at a factor of 10. This also means that everything is subjected to much greater stress than in a refrigerator, which cools approximately 1m³ (35 cubic feet) of air on its own.
