Hot water investing was deveoped for high altitude investing, and it has
other uses as well. Investment is designed to work best at certain
proportions, but there is a lot of latitude. If your vacuum pump isn't
pulling effectively, you can use the hot water method until you get it
fixed... and yes, it can help with bubbles in the mix...

the only thing that hot water will do to your investment is speed up the
setting time fairly drastically.. The best way to invest is to use tap water
at the temp that it comes out of your tap... My castings are always silky
smooth..using this method that is.. I have heard of the hot water investment
mixing and I don't like the sounds of it, the investment will never really get
the time needed to FULLY mix or debubilize... Stick to the regular way.. You
will only be looking at headaches with hot water.... (this is however,,, just
my opinion.. ) Don't fix it if it ain't broken....
