I know it's been a couple weeks. How's it going? Yah, gas dissolves in liquid much better at colder temps, so warming it up helps degas. Also, you don't make bombs with wine that isn't completely degassed. That just adds a little tingle to the tongue when you drink it. Bombs come from wine that is still making CO2 (ie, still fermenting) in the bottle.
Also, the headspace eliminator isn't meant for degassing, it's meant for bulk aging. If you are degassing with the AIO, rather than with time, you have to keep applying the vacuum. The first time you pull a vacuum on a batch, you do it very slowly, because you can make a huge mess with all the foam that suddenly appears. I use a vacuum gauge on mine, the HE is not a good indicator of vacuum. The first time, 22" of vacuum will return to 0 in just a few minutes as the CO2 is released. The next time it takes a little longer. Once the vacuum remains constant, or almost so, then there is very little CO2 left in the wine. Think of it this way: with 100 ml headspace, using a HE, you can only remove 100 ml of CO2 at a time. If you pull a vacuum and leave a HE on the carboy, it might still be collapsed at 3" vacuum (or 0, if it sticks), which won't be doing much to release any more. However, even though it's not a vacuum, it IS mostly CO2 - so no oxygen, thus protecting the wine from oxidation. Careful though, because wine left to degas naturally over time isn't actually fully degassed either. It's in equilibrium with the amount of CO2 in the air above it. Removing more CO2 than would naturally be released over time might leave the wine seeming a little flat, or so I've heard. I have a 2 L reservoir on my AIO setup, in addition to the standard 750 ml wine bottle, so when I pull a vacuum and turn the pump off, it takes almost 3 L of CO2 to equalize the pressure instead of only maybe 100 ml.
