Before i got the last pieces to my system (CPU and MB), i made a little (and somewhat unscientific) test of the amount of heat, the pump puts into the water.
test setup:
Ambient: 22,6
Eheim 1048 (600Ltrs/h @head)
radiator: BlackIce (classic i think)
block: DD Maze2
Senfu temp-diode (which i think i pretty accurate)
hooked it up like this:
pump, radiator, WB, res, pump.

filled and bleed the system, and put the probe between the fins of the rad. I let it sit still overnight, so the watertemp would reach ambient. startingtemp was 22,6C measured between the fins in the rad. fired up the pump, and had it run overnight: the following morning, the temp was at 28,4C, and ambient still 22.6C
made the same test again, but measured the temp on the WB instead - watertemp this time (measured on WB) 29,4C.
So, although not all that much, the pump does add somewhat heat to the loop, but nothing significant (at least for the Eheim 1048).
