similar to the steam pipes - the water could be partly heated by solar-gain pipes that would then carry the water down.. (but this might be strange thing to do - having to pump the water all the way to the surface.. - would it be worth while?)
i like the form of the heat pipes and their fins - the continuous lines fit well with the general themes and forms of the baths - functionally - the system of heat radiation could be used in the warm/hot areas of the baths..?? - dry heat rooms -
