It was actually designed for this, so you could have fresh air during a pandemic in the winter :)
Hmm I wouldn't agree with that. I think the Wikipedia definition [1] captures it more accurately: theft is taking someone's property or services without their consent and with the intention to deprive them of it. In the case of heat, you're neither taking "property" (and "services" would be quite a stretch, unless they provide heating as a service...) noor are you "depriving" them of their heat, so it cannot be theft.
So I wouldn't call it theft. But it seems like a clear case of freeloading.
It's like that roommate that never does the dishes because they know you will do them when it gets bad enough. Are they stealing your time? I suppose not, but they aren't doing their part.
At my current residence, the building bylaws require that all units be heated to 60f during the winter, to prevent this exact scenario. So whether it’s a right is very local.
The original problem 'stealing or not' is most likely moot. The definition of stealing is conventional, unless one believes in some scripture of divine origin detailing such things, or subscribes to philosophies like utilitarianism (which might be fine, it's just hard to argue such things from first principles)
They would spend more if they were heating an outside wall with an average temperature below 19 degrees. The unheated apartment acts as additional insulation. An optimal arrangement would be for the hottest apartments to be in the core of the building with cooler apartments radiating out to the edges. But it makes sense in that scenario to price heat into a shared cost that everyone bears equally. No one would be happy with temperatures below their comfort threshold, and at the equilibrium heat flow that satisfies everyone it's worth just about the same marginal cost of keeping the temperature that way; one might offer slightly lower heating prices on the outlying apartments so that residents who had a very low comfort slope vs. temperature could pay slightly less for heat and be slightly cold, making an apartment free for a resident with a steeper comfort slope at a more affordable price.
I don't see how you can justify calling @kmm a freeloader here. Are they obligated to keep their thermostat higher than 19, even though they prefer the temperature of their apartment at 19? If so, why would you say they're obligated to waste energy? The only way to keep the apartment at 19 with the thermostat set higher would be to open the window continuously.
No. But the fact that there's no simple way to resolve the freeloading doesn't make them not a freeloader. It's a justification/defense for doing so.
But we know it is an advantage to them. They said so.
And freeloading can be passive.
"You're freeloading, but there's not a good way to fix that." seems reasonable to me, in that the derogatory nature of 'freeloader' is basically suspended but it's not forgotten.
The heat flux through the walls with the neighbours will be the same in either situation, since that depends on the temperature difference, not
The previous comment [0] shows the truth of this, if you wanted the room set to 18° you would need to run cooling, which would cost you AND it would increase the neighbour's bills yet again, since now the heat flux is even greater.
Given the heating output will be zero whether 9° or 19°... this suggests that what people are reacting to is @kmm's intent...
Fair enough in the context of social norms, because with the thermostat set at 9° a non-physics normie would assume they were intending to 'steal' heat, whereas at 19° they are 'contributing fairly'... even when the actual output from their heating is exactly the same.
* This all assuming electrical / heat pump heating and an ideal scenario. In the real world there are temperature variations across the room and the idealist model may very well cease to apply.
Similarly, it's not theft to just take whatever is left on the curb the evening leading into grabage collection day.
