ᐅ Building a House with an Architect – Which Heating System?

We plan to build next year. The plot has been purchased, and we are currently working with a friend who is an architect on our house. Now the question is how to heat it. Gas is not available at our new location. So we are considering geothermal heating :-)
Here’s my problem – my wife wants it to be warm, around 23-24°C (73-75°F), especially in winter, she can’t stand it colder than that. Do geothermal heating systems manage to maintain that temperature in a house? If yes, are the electricity costs still affordable?
Thank you very much for your answers.

10 kW is quite large – has a heating load calculation been done beforehand?

There is no disinfection program. It is a buffer tank with an attached heat exchanger for our domestic hot water, meaning there is no potable water inside the buffer tank. Additionally, we have a summer circuit for the bathrooms, which is supplied from the buffer tank—so even when the heating is off in autumn/spring, you still get warm feet in the bathrooms 😉. This does use a bit of extra electricity, but it is a comfort advantage.
10kW for 300m² (3,230 sq ft) of heated area is not really large—the choice of the system was actually made only after the heating load calculation. So far, we are satisfied with the system and the consumption (a lot of the electricity comes from our photovoltaic system as well 🙂).

We have just under 240 m² (2,583 sq ft) of heated floor area and an 8 kW heating load – I’ll discuss the heat exchanger with the heating engineer.
