Gold gas?  The radiant pipe bug can get crazy sometimes

Got any details on this bug? I've just started getting burned by it in my latest colony so I'd like to figure out how it's triggering so I can avoid it and still use rad pipes.

I made a bug report a while back.  Seems when radiant pipes are in a vacuum the temperature will spike real hot or real cold very quickly with no other apparent heat source.

The devs are aware of this bug and hopefully we'll get a good fix soon

I've been observing it in non-vacuum tiles. Seems to be when radiant pipes double back on themselves as my non-looping pipe setups appear to work fine.

The bug seems random.  I have had hot oil freeze and break pipes in vacuums

OR

The pipes would heat up so fast the pipes would melt into molten gold

I've had both happen. I just tested replacing radiant with normal pipes and it's still happening just not as pronounced. I have hydrogen going into a room at 30 degrees and coming out at 55 degrees. The room itself is a uniform 40 degrees currently but it started out colder.

in my current colony I've run into the thermal bug several times, several places.. 

 

There are also several problems with thermal transfer with different state elements. Water cools better then steam, both are the same, and at same pressure. cooling should be equal in both states, it's not. 

 

I have a Aquatuner cooling down a solid block of Diamond glass tiles, in it runs also vents with oxygen. the oxygen heats the petrol up more then the petrol cools down the oxygen. - go figure at 10kg/s with 2.4 thermal capacity, beaten by oxygen, at 1kg/s and 1 in thermal capacity...

Apparently 1 > 24. go figure. Actually petrol has a capacity of 1.76, which would leave me at 17.6 contra 1

The hydrogen loop that cools down the aquatuners come out colder then they entered, and colder then the aquatuner block. 

Just to make a reference point, the Aquatuner should in theory be able to cool down the oxygen by 336 kelvin 246 Kelvin, using petrol as coolant.

You know that is true in real life too?

Thermal transfer is affected by the state of matter

Heat travels faster in solids than liquids, and liquids faster than gases

The reason of this is due to the distance molecules are from each other.  The closer they are the more heat they can absorb

that would be partially true. Usually the reason for this is actually pressure, or as you say distance between molecules.

But since the steam in this case is at same pressure, no matter the state it's in, the distance between the molecules is also the same. In real life this would result in the water STAYING water, because it's unable to state change, duo to pressure.

Very true but don't forget "pressure" hasn't been added to ONI yet.

We make assumptions based on weight and volume

And both weight and volume are equal. Just as thermal capacity and thermal conductivity, ergo both should both cool and heat equally. 

OR let me ask you this, what weighs more, 1kg of steam, or 1kg of water? 

What weights more, 1kg of feathers, or 1kg of led?

I wasn't debating your point, it is true if water was boiling in a sealed environment then the steam would condense as fast as the water boiled

My point was the physics of pressure hasn't been added to the game yet so we can't assume it works like it's supposed to in the real world

Instead they programmed rules for heat transfer depending upon the element

And in the program code steam water and ice are different elements even though in the real world we know it's the same H2O

And i'm not saying you're not right, i'm saying since the element in question has the same thermal properties, no matter what state it's in, should also cool the same. 

I'm perfectly fine with the answer "it's steam, it doesn't cool as well" IF say the thermal conductivity as steam would be different then it is as water.

But since they are both the same, no matter the state, and since there is just as much matter to transfer the heat to/from whether it's in steam or water form, it should therefor also conduct equally. 

 

IF this is not the case, HOW are we then to calculate heat exchange ?

If 1 in thermal capacity changes depending on what state matter is in, or thermal conductivity of 1 is different depending on what state the matter is in, then how can we know how heat should be exchanging, at what rate etc etc?

 

So if 1 in thermal capacity is not 1 in thermal capacity but a hidden value of 0.5x the capacity / transfer when in gas state, how can we know ?
