Given a COP of 5 for a ground source heat pump you can calculate 60/24 is 2,5kW power draw around the clock. Multiply by 5 give 12,5kW heat non stop. That is a lot of heat.

2000 sqft is 185m2 which is a mansion by my standards though :)

I don't know Lapland, but that house is significantly larger than average (97m²) for Finland [1].

Average electricity cost in Finland is €0.184/kWh.

2000 sqft and you call it modest?

And 60 kWh/day is still enormous.

60 kWh/day is definitely not much in climate where temperature can go below -40F/-40C.

21900 KWh in a year is not much according to what source?

Average sq ft for house in US is around 2500sq ft so 2000 sq ft is below median. Ok starter house but not more than that. I understand that houses in Europe are much smaller though due to low incomes and higher utility costs.

I have 2800 sq ft house and use around 30-35 kWh/day in summer. 60kWh/day is high but not outrageously high.
