A while ago I posted a thread asking for advice on a new waterpump for the larger circuit I am planning on building, and I got some great advice (thanks guys!).
The advice was very mixed however, but I finally settled on the CustomSeaLife Velocity One Pump - a pump which many (most!) of you said was a really stupid choice due to it's (98W) power consumption.
Well, I ordered it for two reasons - to do some very primitive testing on it's heat output, and to see how it does for me, my being able to return it and get another pump being an option if my results are not satisfactory (I don't plan to void the warranty, or do anything stupid to it). Not being one to ignore advice, I may still settle for an Iwaki 20 or 30.
The purpose of this post is to ask if anyone has an idea of just *how* I can do some "pump heat" testing on it that will be comparable to similar testing with another pump, my having only the pump, a thermal probe that can measure water temnperature, and a room where the room temperature is very easily controlled.
I believe that there is a mathematical formula for calculating a rough heat output, but I do not have it, and need to consider pump energy efficiency, and design (an unknown factor).
I do not have an Iwaki 20, or 30 (the main two I would like to compare the CSL to), but I have limited access to a variety of cheaper (pet store) pumps for some comparison, and if I can do a "standard" test (unlikely given all the factors ) other people may be able to contribute results as well.
Maybe my idea is a really dumb one, please tell me if it is, and I won't take any offence.
