What happens when the owners of that system go on vacation when it is -20 all 
week?    Something is needed to keep the water in the system from freezing.

Makeup water is not the issue.   (though a system shouldn't need any unless 
you open the system)

I'm not an expert on these systems.    I know that some systems at least 
require anti-freeze, but I don't know how all of them work, so I can't say 
why the system you mentioned does not.
