I was on a run before 10am this morning and, when I got back, hopped in the shower to wash off and cool down. Of course, being Florida, the coldest water that came out of the tap was actually quite warm. This got me thinking: how hard would it be to integrate a home's HVAC and tap water system? When cold water is needed, it would be routed through the cooling fans (radiator?) and then through the HVAC system before being routed to the home plumbing.

I suppose this could be used for heating as well, especially since most in-home water heaters are constantly heating its supply of water anyway.

I wish I knew more about these systems. Can anyone shed some insight?
