What happens if the hot water tank is empty?

Well, maybe not hours after all...
Assuming the storage tank is really empty, so the supply temperature is 15°C cold (temperature from the ground pipe) and you want to heat the storage tank with 185 liters to 45°C.
For this, a heat generator with 6 kW heating power is used.
That takes 80 minutes.

In practice, however, you don't empty the storage tank, unless you are not only taking a bath but also showering intensively.

In case of doubt, a 24kw solar-compatible instantaneous water heater can be connected in between. It measures the temperature of the hot water and heats it up if necessary. However, I basically consider this the second-best solution for new constructions.

Most heat pumps have a heating element. It can be configured accordingly if it is not fast enough using the compressor.

Thank you very much for the answers. The operating manual shows that this SUPRAECO STE 80-1 ground source heat pump does not have the heating element.

That is just a checkmark on the order form.

But of course, it is inefficient

In a 4-person household, a storage tank that is too small can be a problem. But it doesn't have to be, if you make sure, for example, not to waste water. I think that's okay. I had about 80/90 liters in the RH - after a full bath and brushing teeth, a small dishwashing was no longer possible. 180 liters can be enough :)
