So for example, let's say I have a 3 PPC build with 20 DHS, my max heat is ~64 and my dissipation is 3.4. So if PPCs had a heat spread time of 3.0 sec (it's whole recycle time). When I fire, rather than putting me at around 45% on my scale, it only puts me at 19%. The next 3 secs I may gain a couple % on my heat scale, but for the most part for 3 seconds after firing PPCs, I hover at the 23% mark.
This is handy for mechs that generate 40+ heat in an alpha, but after a second or so shutdown, have already dissipated enough heat to be below the 80% mark.
I'm not sure energy boats honestly need it, but considering the constant complaints about the high heat weapons of the LL and PPC families, I figured this might help outside of lowering the heat outright.
tl;dr Heat spread would give energy boats longer operational periods, but longer shutdown periods as well, so you don't have to deal with override.
