Loop to loop heat pump

Hello all,

I've created a Loop-to-Loop Heat Pump. This type of chiller requires a
heat sink / lake for the condensing water loop. When I run the
simulation, I get the error:

"Lake loop has no attached primary heating equipment."

At the risk sounding ignorant, how do I attach primary heating
equipment? (I've tried what I think are the obvious solutions) Thanks,

Jim Crockett, P.E.

Hi Jim,

You might need to add a ground loop heat exchanger to your lake/ well loop.
