I use around 70kWh/day (but nearly zero in summer and probably 4x that on colder days).

Heating is a heat pump with probably 300% efficiency (i.e. 3kW heat for 1kW electricity). Walls are 300mm insulated wood frame. Triple glass windows. -20C for at least one week every winter. Could probably lower the consumption by recycling more heat (none of the wastewater heat from hot water running down sinks is recycled for example).

Thats incredible. We use up to 30kWh/day (heating a poorly insulated house), which is almost double the national average household daily usage here in Australia. I guess you really do use alot more power living in a freezing climate.

In a climate I live in (Latvia , -20 degC for a few weeks in winter), reasonable energy consumption for heating of single-family house is around 100kWh/m2/year.

My 200m2 house is slightly worse at ~120kWh/m2/year, or around 24MWh of energy per year (that also includes domestic hot water though).

With a ground/water heat pump it should translate to ~5MWh of electricity per year, or about the same as my current yearly electricity consumption.

I was fairly resistant to Ugg boots and the like, but I realised why they are so popular this year. You really can get by quite comfortably in a Sydney winter without heating. And my home gets cold.
