This is confusing me a little bit.
At 60Hz the head and flow is larger, yet according to Iwaki's
PDF the amount of heat dumped into the water stays the same.
So the 60Hz version should definately perform better, right? :shrug:
I'll be testing a few pumps myself soon, and I don't want to make mistakes.
EDIT:
Unless of course by output they mean the amount of heat transferred to the air?
If that is the case then the amount of heat dumped into a loop by the 30RZ is very low; that's very unlikely.
I guess their numbers are just way off...
