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?

Karsten, these are usually the people who think they are saving money. In new builds, they often operate the system in on/off mode without making any adjustments.
The purpose of the settings is to save as much as possible while maintaining maximum comfort and, above all, to ensure the system runs in a way that is gentle on the materials.
We also have a gas boiler running in our house. I spent a long time adjusting it as well. Now, the boiler runs continuously on the lowest flame setting when the outside temperature is below 7°C (45°F). And all this while maintaining a constant indoor temperature of 22°C (72°F). Nobody here has to be cold at all.

Measured and perceived temperatures can vary significantly from house to house (and, of course, from person to person). For one person, 21°C (70°F) in house X is comfortable, while in house Y, a comfortable temperature is only reached at 24°C (75°F). Person B needs 23°C (73°F) in the first house, but in house Y, the supply temperature still needs to be around 25°C (77°F)...
