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.
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.
kWh is a unit of energy. Regardless of whether it is in the form of electricity or from burning fuel. So it is actually very related, and much more useful than a measurement of volume I’d argue. The measurement is of course done in m³, but then a conversion factor based on several factors is used to convert to an actually useful unit.
A m³ of gas really could be anything depending on pressure, temperature and constituents.
(Brace yourself for Much 'Merica) Several gas utilities I’ve had in the USA measure natural gas CCF, which is 100 cubic feet (at some standard temperature/pressure), which happens to be almost exactly the same as a Therm, or 100,000 BTU.
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.
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.
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.

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

Yeah, even firewood can be (and not uncommonly is) measured in kWh
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.

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).
