Hold door open command doesn't lower inside temperature

[Hanuman]

I noticed when I built a camp fire inside a structure that it would raise the temperature to about 30C/85F so my pawns were getting to hot. Even with the door held wide open to the outside (0C/30F) using the hold door open command, the small space containing 3 beds wouldn't cool down at all I assume I need a vent in the wall maybe?

Yeah the vent works better, but open door helps too.

Oh but you need that wooden cooler, that offsets the fire usually.

Open doors don't seem to cause heat exchange like they used to. Neither do holes in the ceiling. I don't know when this changed, but you can punch holes in the roof in -35C weather and still keep a comfortable temperature inside. I use it for my ground-scanning radar. Just remove the roof right over it and let people scan in comfort in my frozen hell of a map.

How much heat escapes through an open door or hole in the roof depends on the size of the room. It definitely still works and hasn't changed at all as far as I can tell, my current base is in a permanently below 0C map with a tribal start, and I use open doors to spread the heat from campfires, it's the only way I could grow my nutrifungus under a mountain since the campfire light would kill it otherwise. One campfire in a like a 3x6 room with a door held open into a room with 126 tiles of nutrifungus, it was able to keep those mushrooms at 12-16C even when it was -40C outside, while also heating my dining room up to 5C.

Hope this imagine works. Heat dispersion throughout buildings using a heat source works fine. But the "heat escape" mechanic doesn't seem to work properly anymore when it comes to spaces between outside and inside. I think this changed since 1.3 and might be a bug.
The above room at night is 30C+ with door open and exact same temperature (the game doesn't detect a change I guess) with door closed.

Ah I see what's going on. Campfires only heat up to about 30C max it seems (I was not aware of this, not sure how long they have been that way), that room is small enough that even with the door open the campfire is able to maintain that temperature. What happens is you open the door to let the heat out, but the campfire then starts to produce more heat to try and keep it at 30C.

if you have both a campfire and a cooler they can cancel each other out but the cooler wont cool below 17C so the result is a room that more or less keeps with the outdoor temp but will stay at least at 17C. 2 coolers and a campfire will usual keep a room at 17C (though the wood cost is pretty high)

A room that size, I'd try two torches instead of a fire.

Ohhh gotcha lol makes sense the fire is too powerful for that little room
