In the installation files, there is an exampel of a heat exchanger - hot air passing over a loop of cold water, as I remember from the training. The water pipe ends are closed off with lids, as are the airpipe ends.
Now: What if I want to make a closed circuit of the water? Say the water runs through a radiator and gets cooled down, and circulated back to the inlet?
Anyone having tried that?

It can be done. Just like a rad system, you need an internal fan to drive the fluid motion.
