Heaters do not work, Air Canisters do not work.

[TrustScience]

Currently there exists no way to reheat the station or resupply air. 
This feels really broken. Please fix this, it has been this way for quite awhile. 

There must be a way to repair problems with the stations heating and air supply. Heaters either do not work or are not hot enough. Air Canisters do not work. This has worked years ago and it has been broken for too long. I will fix this if you let me code it really needs to be fixed.

That's odd. Last time I used one at max output it burned my lungs.

Keep in mind the way heat ramps up in this game

if its super cold it takes stupid long to heat

If its already hot, you can create an inferno

this is a faulty bug report, if that stuff broke it would break the whole game

you probably didnt let the air circulate, there was a hole somewhere, didnt have enough air canisters, or it was literally space cold before and will take a while to heat up

In general due to the way atmos works just opening an air canister in a large room won't spread it evenly across the room, it will just result in a lot of air on the tiles directly surrounding the canister and the rest of the area still being decompressed.
