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.

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.

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?
