There's no reason a draindown system can't work in wintertime.

You can risk it. I'm investing in the glycol flat-panel system.

Nick's point was that a draindown system without antifreeze can be
designed to be safe in winter.

I know what his point was. He might even be right. I, however, have no
intention of risking it. I can, and will, profitably install a glycol loop
system with heat exchanger.
