I am trying to find out what the loop water supply temperature should be on a commercial water source heat pump. Thanks for your help

the range is to cover both ends of the WSHPs modes you want a load on the condenser in the heating mode,but not to high when in the cooling mode 80F-85F .seen it as high as 90F cycling the in line boilers off to maintain in the dead of winter.

It ain't going to get any lighter looking at it!

I have this set up in my building,we run our closed loop water through a heat exchanger and try to maintain our tower temp at 80 degrees since this is the main factor of our closed loop temp but in Maryland with high humidity and temps sometimes its hard but the range stated in past post I agree with

Here in the Pacific Northwest, I run must of my building loops around 80-85ºF range. Some of them use a heat exchange, others pipe loop water directly to the Cooling Tower. Boilers make up for the drop in winter time.

83 degF to 87 degF is a good temp range for a tube and shell condenser. But the manufactuer might have a different temperature range, so check with them if possibile.
