Hello!
I'll start.
Heated area 200m2 (2,153 sq ft)
KfW 55 standard
Mechanical ventilation with heat recovery
Current outdoor temperature 6°C (43°F)
Heating energy consumption including hot water 35 kWh
Electricity consumption 9 kWh
COP 3.88

150mm (6 inches) diameter, probe itself 32mm (1.25 inches). It is made of PE100-RC. According to standards, the material lasts over 100 years at 20°C (68°F). As mentioned, it should clearly outlast me 🙂
The space around the probe is sealed with cement slurry.
But this shouldn’t turn into the brine water heat pump thread, that one already exists 🙂

That’s quite extreme, we actually have ideal soil here, no stones. Back then, I got three quotes, all were around 15,000 euros just for the drilling. The brine system would have only paid off after 50 years, so it wouldn’t have made sense even with subsidies...
But you always have to do your own research because many things can’t be directly applied to your own location or situation.

Cross-comparison:
Oct 1 - Mar 1:
1050 m³ (37,100 ft³) gas => approx. 400-450€
No, I’m not from the gas lobby :p
But I find the thread and the discussion very interesting.
@guckuck2: Do you have the additional cost of geothermal heat pumps compared to air-to-water heat pumps in mind?
Does it still make financial sense to combine geothermal with photovoltaics? (financially, not ideologically :p) This again shows that a heat pump can’t compete with gas. Economically, gas is unbeatable, although unfortunately it is not available everywhere. Much lower investment and lower operating costs. If you also factor in repairs for heat pumps, then economic efficiency is not even worth discussing 🙂

09/26/2020 – 03/03/2021 2,161 kWh total household electricity including hot water, 131 sqm (1,410 sq ft), 22–23°C (72–73°F) indoor temperature, KfW 55 standard, timber frame, southern Baden Did you exclude the heating here, or is something missing? You once posted 55 kWh for 48 hours. This would actually contradict a total household consumption including hot water + heating for the mentioned period of 5 months + 1 week. Do you have a separate meter for the air-to-water heat pump?
From 10/01 until today, we have a total household consumption of 3,318 kWh. Of this, 2,184 kWh is grid electricity usage.

We have a total house consumption of 3318 kWh from October 1st until today. Of this, 2184 kWh is electricity drawn from the grid. I think he does have gas, right? I don’t understand his post either.
