I'd test it in operation. That icon is probably a red herring, the cross-loop transfer is a bit tacked on now, I will look into it. 

The design did work fine in operation. For now I'll just assume that the red thermometer on a heat exchanger is meaningless.

[Dep_Opt]

So, messing around with this in the VAB, and hit a slight issue with having more than 3 loops: The list won't scroll. It twitches like it's trying, but doesn't go any further down.

Also, the reason for the amount of loops is :1 reactor separated off with it's own cooling, then an ISRU and a drill, each with it's own loop feeding into a shared cooling loop that sinks enough heat for both, but each is at their preferred temperature. 

Changing the order I've split them off has helped, pushing the known to be stable reactor loop to the bit that can't be seen, but it's still an issue worth bringing up either as a heads up or to work out where I dun goofed.

I don't know why this is happening, banged my head against it for an hour this morning to no avail, but I'll keep looking at it. 

Sounds like a nice setup though, looks like that part is functioning as intended and is useful!

Can you post a picture of your specific setup? I tried to reproduce this this morning and couldn't with a simple set of loops.

[mikegarrison]

Easier to describe it. I don't have a photo-sharing account set up anywhere.

----------

Loop 2 is a drill with a heat exchanger pumping heat to loop 0 at +400.

Loop 1 is an ISRU 250 with a heat exchanger pumping heat to loop 0 at +300.

Loop 0 is a MX-1 reactor with four XR-500 radiators.

-----------

The simulator says everything should be working, and in the field it does work. But in the simulator the two heat exchangers both have a red and black thermometer that faintly pulses. I thought that was supposed to indicate a problem.

(It seems to be doing the exact same job as @Dep_Opt is doing, although I went for the slightly simpler option of just pumping all the heat to one set of radiators instead of using two sets of radiators.)

Ok that helps. It might be some specific combination of fluxes and it's good to have a case I can test out there.

I seem to have a bug or something, everytime I timewarp and I look at the loops every radiator/cooler/heat exchanger has *not found* Even after not touching the loop id and leaving it at zero does the same thing. anyone got a fix?

[CDSlice]

OK, so I'm not 100% sure if this is a bug with SystemHeat or FFT but my Fresnel engine isn't getting cooled at all by my radiators. They are both set to the same loop and in the VAB it says I have more than enough heat rejection and in flight the overlay UI says they are on the same loop but when I activate the engine I get 0 heat rejection which makes the engine almost instantly overheat. It also persists through a save/reload although for some reason after reloading my loop ID changes from 1 to 3 for the engine and my radiators.

Here is my KSP.log after I restarted the game and tried it again with the same results as described above. Let me know if there is anything I can do to help troubleshoot.

I figured out the issue, if you change the loops while in flight at all you gotta completely restart ksp, seems like changing loops during flight makes it bug out.

OK thanks, sorry for the duplicate bug report, didn’t realize it was that issue.

How would a systemheat config look for an engine that can switch between 2 modes? say, that Project Eeloo bimodal nuclear air and nuclear space thing in Near Future Aeronautics (i think).  Would you just have too add: 

"engineModuleID = Shcramjet"

 

(with "Schramjet" being whatever the modes name is) too the ModuleSystemHeatEngine ?

More or less, yeah. You would have 2 ModuleSystemHeatEngine instances, one tied to each engine.  The exception to this is if it's a fusion or fission engine, where that support is baked into the appropriate modules.

I can't reproduce this, but maybe it's because I fixed it with the other bugs. Try updating to 0.3.7.

SystemHeat 0.3.7

• Fixed a NRE on deletion of parts in the editor
• Fixed scrolling of UI loop list
• Fixed heat exchangers always showing as overheated in overlay
• Fixed converter module not actually simulating heat in the VAB when set to simulate
• Fixed more bugs in generic converter patch (PocketBrotector)

Editing this down because most of what I had written became moot when I did more testing. Ugh.

Long story short: When I try to reject heat from an SRB or from reentry/really fast flight in atmo, I seem to need a crazy amount of radiators, but I can't see where to find out how many. Is there a way of knowing how much total heat is being applied to a vessel while in flight at a given point in time, so I can test and see how much cooling would be needed for a hypersonic craft X at speed Y, or a reentering craft, or a craft with too many SRBs or something? (As opposed to numbers/simulations in the editor that seem to account for stuff like reactors/drills/etc.)

Also - when testing with Heat Control to understand better how SystemHeat works, I noticed (on the launchpad)  that graphene radiators had 'cooling efficiency' (or similar phrasing) at ~ 28%, while large stock extending radiators had ~88% (in atmosphere). Is this a function of the heat of the SRBs not being 'hot enough' for the high-temp radiators? ~30 large deployable stock radiators successfully cooled three kickback SRBs (infinite fuel on) I used for testing craft/engine heat rejection, but even 80 of the graphene radiators couldn't stop them from overheating...

EDIT: should perhaps note that I'm also using the extra SystemHeat patches, if that's important...

SystemHeat focuses on heat from "systems", like reactors, etc. Reentry heat is a completely different problem  and isn't handled by this mod. I have not disabled any stock cooling functions so the weird bit where you can use radiators to reject reentry heat still works.

Yes efficiency is a product of loop temperature. Lower temp radiators like stock ones cap out at lower temp so they hit higher efficiency with lower temp systems.

Makes sense, thanks. Since reentry / speed in atmosphere isn't the same system, then, I assume it's probably not possible to see 'this many kW of heat are being applied to the craft / to this part' kinds of stats that are available with stuff on SystemHeat loops - too bad! Insane as it is, it'd be fun to know (up front) roughly how much it would take to make a radiator-packed "just point it at the planet" reentry pod and/or an orbital-speed-in-atmosphere plane. Trial and error, here I come...

I am liking this mod quite a lot. I am also quite looking forward to the electricity system being converted to kW as well (as I assume that is the plan lol).

I am using this mod, plus all your other Near Future mods, and there are a couple things I noticed so I just wanted to give some feedback on them:

• Had one situation in the VAB where the total heat loop said I was 5 thermal kW over, but adding more radiators didn't make a difference, yet when I ran it in the simulator in the VAB at various warp multipliers nothing started overheating. I ended up just putting things into 2 separate heat loops and it stopped doing that. Possibly too much heat in 1 loop was causing it, but the simulator didn't seem to care though.
• The Near Future nuclear reactors don't show E/C output, just kW. I figured out that 1 EC = 1 kW myself, as it shows the EC output when actually in flight, but the screen that Near Future adds that shows electrical usage does not show the reactor as generating EC.
• The drills don't show as consuming any EC in that same Near Future screen.
• The drills now consume more EC than the game says they will.
• Nothing has passive radiation cooling. If I turn off my radiators my nuclear reactor and drills will apparently stay heated up and ready to go at the same temperature years later.

I assume you are already aware of these things, but figured it would help someone else if they come across similar things while they are trying this out.

 

EDIT:
Struck out that one point, that was my own reading comprehension failure.

You're probably not going to be able to do this, stock radiators do some weird self-disabling in certain situations that is player-transparent.

If you can make this situation for me and take a screenshot I can look into it.

Yeah I do know that the Systems Manager window needs some fixes to handle some things.

I guess that's true and I should probably add some kind of decay.

I'm getting messages in my logs that seem related somehow to SystemHeat - however, it's a very modded install, and there are lots of other issues (apparently, because... problems). Trying to see what's causing what. Is this meaningful?

Thanks for taking a look - I managed to get rid of many of the errors, at least for now, but SystemHeat is still in there throwing exceptions at times. I gather that this may be because of other errors, but figured I'd pass along a new log just in case it's useful.

Sorry, that log is also gigantic.

Mr. suiptom. 
There is a tool in the VAB that will show you how much Cooling capacity you need. 
Make sure you read the wiki too
