That’s a perfectly normal number for any home that isn’t very new and perfectly insulated.
My 37sqm appartment needs approximately 5000 kWh in natural gas per year, 876 kWh last December, so 28 kWh per day on average. The building is admittedly old and not perfectly insulated but it’s also not a log cabin out in the open in Finland, but instead a flat enclosed within 3 other flats in the middle of cosy, never below -8C Germany.
21 kWh in a log cabin in Finnland actually seemed pretty low to me. It’s sort of obvious OP is using a heat pump and the cabin must really be absolutely tiny.
I live in a desert climate and I have an all electric two bedroom, two bathroom, attached home. The unit has an area of 109sqm. Over the course of the year my monthly average is 622 kWh. This includes times where I run the roof-mounted air conditioning unit all day and its 46C outside. It actually becomes hotter when the sun goes down before getting cooler again because the ground absorbs heat during the day and it radiates back out to space at night passing through the city. I only use air conditioning for 4.5 months a year, the rest of the time I open the windows and use fans.
2022 Average: 622.6667 kWh or 20.755
2022 Air conditioning months average (June - September): 828 kWh or 27.625 daily
2022 Non air conditioning months average (including May which is partial): 519.625 kWh or 17.320 daily
The daily numbers lose some fidelity because I’m lazy and divided the averages by 30.
This is my total energy usage including my hot water heater, two computers, TV, electric stove, often used oven, lighting, fans, and various small appliances. You figure that the rough average air conditioning energy usage is the difference between the daily averages or 10.304 kWh per day and 309 kWh per month
Considering urban development where I live is nearly water neutral and I have a mix of solar power and natural gas generation, it is funny to me because people in northern parts of my country tell me about how where I live must be somehow more unsustainable than where they do. My region also grows a significant portion (read 90% of the total) leafy green vegetables they eat year round.
Cubic meters (or another similar measure of volume) is what I’d expect. It’s the conversion to an unrelated and theoretical (since it’s not actually being converted to electricity) unit that confuses me. I presume it’s to make it easier to compare electric vs gas heat, but the variable efficiency of burning gas and the existence of heat pumps ruin that.
1kw is a small heater. 0.8kw is a tiny one. 0.8x24 is 19.2. Assuming they have other basic appliances, that’s already more than enough to account for their usage.
50kWh and closer to 90kWh on days like this. It’s a log cabin and I’m keeping my root cellar and insulated shed above freezing aswell. Even running a 1kW heater all day would result in a consumption more than 21kWh and that wouldn’t keep any house warm.
How are you using 21kWh/day heating a small home? Do you have any insulation at all?
Probably because it’s about -35C outside.
Dude is basically living on the set of The Thing at this point.

Just because I love numbers

Why are you measuring natural gas in kWh? How do you even measure that as such?
Very common in countries that use the metric system (ie literally everywhere except the USA). It’s measured either in kWh or in m^3
Cubic meters (or another similar measure of volume) is what I’d expect. It’s the conversion to an unrelated and theoretical (since it’s not actually being converted to electricity) unit that confuses me. I presume it’s to make it easier to compare electric vs gas heat, but the variable efficiency of burning gas and the existence of heat pumps ruin that.
My meter measures it in m3 and my supplier, knowing the exact caloric value of the product they’re selling, tells me in kWh on my bill.
edit: m3 of course not 2 lol
A tiny heater running all day would do that.
1kw is a small heater. 0.8kw is a tiny one. 0.8x24 is 19.2. Assuming they have other basic appliances, that’s already more than enough to account for their usage.

Outer walls in new homes in the Nordic countries are often 25-30 inches thick filled with insulation. They will keep out some cold (and some heat).
