For me humidity is a plus in winter but I agree that the same kind of noxious chemicals needed to keep a hot tub bacteria and fungal free may be needed. I think we need to visit some indoor pools in winter and see what the mold problems are.

Your closed system will need to suppress algae and mold as well unless you use something other than water which has some obvious disadvantages. Algae on glass will significantly reduce absorption of solar heat.

Every site I have read says that it can't be used as the main source of heat. I'd like to prove that wrong and be able to figure out what it would take to overstore heat and release it controlled without much mechanical. My main thoughts at the moment are about room air conductivity.

I just don't want you to ignore the aesthetics to get a perfectly working physical model as many engineers may be inclined to do.

Didn't the Romans use this method? Didn't they run hot water through pipes under the floors? Why do you suppose the practice came to an end?

No doubt. We'd have quite a water bill now. I don't know what went on between times but we did end up with steam heat for a while. That sounds easier and maybe a tad more water-saving. But there were all those boiler explosions. Finally we had "hot air" heat. Do you see a good reason to go back to water? Just pondering.
