Doesn't matter, it's water, it will mix, the heat will definitely go somewhere, if anything the water going fast might be better but the difference is not really worth the drawback of having it crammed in somewherewater might pass through without being heated enough
I should have added a “it doesn’t matter” choice. Maybe I’m overthinking this
If constant cooler water is rushing by the heater, it’s not getting heated. The only way for water to heat in a small section with constant rapid turnover is to be in close proximity of the the heater, but with the speed it passes through, it won’t be in that section for more than a second or two, and that’s not enough to heat it properly
But if there is a larger section, then yes water still rushes by, but there is also a large volume that remains behind, that retains heat from the element. And then new cool water comes into a warmer section, so the new water doesn’t need to come in close proximity of the heater to be warmer, it will mix with water that already is warmed.
Ok I know I’m overthinking but this makes sense. And I want to use A or B ideally but I feel it’s not efficient. Someone explain to me why A would work

It doesn't really work that way. Faster moving water will not heat up as much, this is true. However, the total heat energy going into the aquarium is the same in either case. (Within reason)
Rapid turnover with little heating is good, that means the whole tank is heated up little by little, and the heater is staying on until the whole tank is at temp, rather than a small amount being heated up all the way, turning the heater off and then mixing in and cooling down again and the heater turns on again.I should have added a “it doesn’t matter” choice.

Sure the water leaving the heater is colder, but there's more of it, carrying the same total energy
But really it doesn't matter all that much
The heat transferred to the water will be the same, just more dispersed at the point of heating. Your tank volume should heat at the same rate.I understand energy ( heat in this case) can’t be destroyed, only transferred. So. How’s that work in realty with A?
I normally run 2 heaters and in a similar sump I would use B and C but really have no reason why lol. As long as it's wet and water moving it's good. My latest build I'm using A and C after looking at it.
