Another data point: 180m2 house renovated in 2009, very well insulated, brand new 5.1 COP GSHP equipment we averaged 36 kWh per day for heat in January. We generate some hot water from that but our primary hot water is resistive electric.

Another data point: Our fairly old house, heated with an air heat exchanger, use about 60 kWh per day during the winter months. The power draw for heating is reduced to almost nothing during the coldest period when the outside air is too cold and we use firewood.

Apart from heating the house, we also use some power for hot water and pumping water from the well into the house.

Full size fridge and freezer from 2015, forced ventilation fan (which is probably around 35-60w), one server (a repurposed office computer) and 2 WiFI hotspots, one of those Google speakers, a router (USG) and a PoE switch. Those are the big ones.

We didn't build the house, so there are all kinds of standby stuff (including needing smart lights for most lights, stove, towel heaters).

I didn't turn these things off because my mother in law is using the apartment a little while we are gone.

4kWh is 166W average, which is a refrigerator and a couple WiFi access points, a camera, a home assistant device, and some other random plugged in devices (i.e. cordless phone).

Not much even in an efficient house.

Indeed. I just looked up the heat loss for my house: 213W/ deg K. So, to maintain 20 deg C inside with -20 deg C outside requires about 8.5kW of heat energy (200m2 single-family house built around 2008), or approx 200kWh/day.

Even a very well insulated home can use quite a bit of electricity.

The most rigorous standard for home efficiency, the Passive House standard, stipulates that no more that 15kWh/m^2/yr is used for space heating. For a 200m^2 house, that's 3000kWh/yr.

Given a 120 day (4 month) heating season, that's 25kWh/day average just for space heating. Obviously it varies quite a bit, with some days much higher and others much lower. Add in other electricity uses, like refrigeration, laundry, and you're easily at 40+ kWh/day even in an efficient Passive House.

This means that you pay ~4 USD per kWH. That's almost 12 times more expensive than in Germany where electricity is supposedly expensive. Where do you live?

You pay more than 4 USD per KWh? Wow.

Do you mind shared where this is?

Its going to be 39C at about 60% humidity today here with a bright sun beating down. My home has some decent insulation, double paned low-E windows without metal framing, thick attic blown insulation, etc. AC is set for about 26C. I'll probably still use about 70kWh of power today with the majority of that being the AC. A pool pump uses a good bit of power too though, pumping about 60,000 gallons of water through the filters uses a good bit of power.

You can do 3kWh maybe if you are not cooking using electricity or running a cleaning machine for dishes or clothes.

I've installed an electricity meter 2 weeks ago, and the lowest it got was 4,8 kWh/day in a 2-person Croatian household, although I do have a small Synology NAS running 24/7 and we have a TV on for a couple of hours.

24kWh a day here. Fairly large house near Cape Town, South Africa. This is excluding heating in winter, for which we mainly use a slow combustion fireplace and also natural gas. Stove is also natural gas. Rarely use AC for cooling.

> how is 100 kWh/day even possible

Easy, live in a house 4x the size of a 2-person Dutch household and in a climate that averages 10 degrees C warmer, like would be common in the southeast US.

80 here

Update. Local price comparison site was just updated this morning. Price here would be between 14569€ (.40€/kWh) and 17308€ (.47€/kWh) depending on the supplier chose. This includes all taxes and surcharges.

60 kWh/day would not be enough to heat a modest sized house (~2000 sqft) in Lapland, even with geothermal heating.

Unless you meant 100 kWh/day, which would be doable, but I think only with geothermal.

I used about 8 KWh/day when I lived alone in a 1550 sqft townhouse with gas heat and cooking. That ran my IT equipment, refrigerator, and blower fans for heating and exhaust. No AC usage.

Now I'm in single family home and my energy use is bonkers, but most of that is heating while I'm missing part of my roof and an entire exterior wall. It should be criminal for a town to take two years to approve permits.

I'm using 5-7 kWh/d. Pretty constant. Includes washing machine and induction stove, but excludes heating the apartment and hot water.

A air-water heatpump for heating that shower water would pay itself back in a few months. Solar panels would get the rest. Water is probably your biggest energy sink.

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.
