Let's do some math! MATH IS FUN!!! The procore has a thermal resistance of approximately 0.02 C/W, and let's assume that ALL 35 watts from the pump went into the water. 35 X 0.02 = 0.7 degree increase in total water temperature. Not really all that harmful, hmm? Submerging a pump will allow a slightly higher flow rate, and that may offset the heat a little bit, but not enough. However, if what freeloading says is true about the inline one putting 28 watts into the water, then the difference is 7 watts, or 0.14 C cooler water. Cathar, I believe, estimates it at around 20 watts, or 0.30 degrees cooler than a submerged pump, that is impossibly transferring 35 watts to the water. By the way, fhorst, it sounds like the entire setup is different, and that makes ANY results you got irrelevant. Also, saying the water was "slightly" above ambient in the first case, and 20 degrees above it in the second case also reduces the relevancy, as "slightly" could, in fact, mean 73972 degrees Celcius.

Sorry, rocketmanx, I know that wasn't the answer you were looking for, but I was trying to bring a little bit of fact into the discussion.
