In a far more normal situation of a normal 1 GPM flow rate the heat is around 10 - 15 watts.
That level of heat is far too little to make a noticeable difference to water temps. Far less than a whole degree ... more like 0.1 degrees C
Watts = Joules per second
Getting the heat load value in joules allows you to calculate the increase in temp, so here we go.
18 joules will increase liquids temp by 0.009degrees C (or 0.009478171376388degrees C to be exact)
WAY less than .1 degree C
Now lets factor in that D5s have a tenancy to dump their heat into the surroundings, rather than into the water. Seeing as how we don't know the exact % of the heat that is being dumped into the ambient air, and the % of the heat actually being added to the loop, we can only conclude the heat the pump makes will be so insignificant it won't matter in any way shape or form unless you have around 20 pumps in your loop, which is just insane.

That isn't necessarily true, if his reservoirs output is above his rads input, and it's rads output is above his pumps input, and he has a really nonrestrictive radiator then there is no reason why you /couldn't/ do that, nor is the a reason you /shouldn't/ do that, however; that requires very specific circumstances in which it WILL work properly
In short, if possible keep it res->pump in a loop order, if that simply isn't at all possible for some odd reason, then alternatives are to be contemplated.Edited by ZytheEKS - 6/9/13 at 1:50am
